The Indian River County Board of County Commissioners (IRC Board) and the City of Sebastian are initiating this conservation effort with cooperation from the School Board of Indian River County (School Board). The IRC Board and City of Sebastian will serve as the lead agencies for implementation of the Sebastian HCP. The School Board will participate by allowing IRC to conduct recommended conservation management actions on targeted School Board properties. The IRC Board and the City of Sebastian have agreed to participate as co-applicants, hereafter referred to as "Applicants", in the implementation of the Sebastian HCP. Documentation of IRC Board (excerpts of minutes from 11/16/00 IRC Board meeting) and City of Sebastian City Council (Resolution No. R-00-05 dated 1/12/00) action authorizing this inter-governmental partnership and the transmittal of this Sebastian HCP to the U.S. Fish and Wildlife Service (FWS) is provided in Appendix A. The School Board agreed to serve as a cooperating entity. pursuant to Resolution No. 2000-05 dated December 14, 1 999 (see Attachment A). This resolution establishes 1 2:t acres of scrub habitat at Pelican Island Elementary School as an outdoor environmental classroom and allows IRC to manage this property for conservation of scrub habitat and Florida scrub-jays. The Applicants are seeking an incidental take permit (ITP) from FWS pursuant to section 10(a)(1)(B) of the Endangered Species Act of 1973, as amended (ESA). The Applicants are requesting that the ITP authorize, for a period of 30 years, the take of the threatened Florida scrub-jay (Aphelocoma coerulescens) incidental to residential home construction within 317 one-quarter acre Sebastian Highlands lots (79.3:t acres) that are currently recorded at the City of Sebastian's Building Department pursuant to FWS designation as potentially occupied by Florida scrub- jays. The Applicants recognize that authorized encroachment of residential development within the 3.1 7 Sebastian Highlands lots presently subject to FWS regulation, as residential build-out occurs, will likely result in the expansion and/or shifting of Florida scrub-jay territories into new, although poorer quality, habitat areas of the Sebastian Highlands subdivision. If these newly occupied platted residential areas were not considered under this Sebastian HCP, then they would be individually subject to section 9 of the ESA prohibitions. To ensure that the ITP provides sufficient regulatory coverage for lot owners who do not currently have scrub-jays 1 I I I I I I I I I I I I I I I I I I I occupying their lands but who may in the future, the Applicants are seeking coverage for the entire platted residential area within Sebastian Highlands. As a result of participation either directly or indirectly in the Sebastian HCP, the City of Sebastian and School Board also foresees the possibility of future development impacts on scrub-jays on an 88.1 :t acre commercial parcel located on City of Sebastian-owned Sebastian Airport and on a 4::l: acre parcel located along the southern boundary of the Pelican Island Elementary School grounds. These parcels do not currently support scrub-jays and are not suitable for use by scrub- jays at this time, however habitat management actions directed by this Sebastian HCP to enhance the dispersal potential of scrub-jays through these mesic habitats could result in permanent or seasonal use of these parcels at some point in the future. Therefore, the Applicant requests that the ITP address the potential for take of Florida scrub-jays incidental to future commercial and school development on said parcels. The Sebastian HCP proposes a combination of compensatory mitigation measures for compliance with the conservation requirements of section 1 O(a) (2) of the ESA. These mitigation measures include: · Conservation, restoration and management, in perpetuity, of optimal Florida scrub-jay habitat conditions within 324:t acres of potential scrub jay habitat to support additional scrub-jay families and within 6.5::l: acres of mesic flatwoods to create a 100' wide dispersal corridor at the Sebastian Airport to facilitate movement between scrub-jays subpopulations. This perpetual corridor adjoins and runs the length of the northern runway. These total combined 330.5:t acres are referred to herein as the Scrub-Jay Habitat Compensation Areas and are comprised of: 280::l: aces of potential scrub-jay habitat on lands acquired by Indian River County under the County Environmental Lands Program (the North Sebastian Conservation Area, the Wabasso Scrub Conservation Area, and the Sebastian Highlands Conservation Area) 32::l: acres of occupied scrub-jay habitat in the northwest corner of the Sebastian Airport property, plus the 100 foot wide (6.5::l: acre) "perpetual corridor" buffer along the northern runway 12::l: acres of occupied scrub-jay habitat on the Pelican Island Elementary School campus currently used and managed for outdoor environmental education programs. · Enhancement of scrub-jay dispersal opportunities on the Sebastian Airport by: 2 I I I I I I I 'I I I I I I I I I I I I 1.) conservation and management of an existing 20':t wide hedgerow located between the municipal golf course and the southern runway, in perpetuity, to create a low vegetative structure (~ six (6) feet high) and 2.) provision for interim management of an open landscape structure on an 88.1:t acre commercially zoned parcel on Sebastian Airport adjoining the subject 100' wide perpetual corridor. This provides for a total 94.6:t acre dispersal corridor at Sebastian Airport prior to the City of Sebastian's commercial development of said parcel. The FWS and Applicants agreed that future ingress/egress into the 88.1 :t acre commercial parcel on Sebastian Airport would include a 40' easement along the extreme western boundary to allow for expansion of Roseland Road and an 80' easement along the northern property boundary extending east from Roseland Road to the commercial development site. · Elimination of the multiple negative effects potentially resulting from habitat fragmentation by formalizing the City of Sebastian's abandonment of plans to extend Gibson Street (130 Street) through the North Sebastian Conservation Area core scrub habitat areas. The FWS and the Applicants agreed that use of the "habitat-based approach" for development of the Sebastian HCP would provide the greatest benefits to the Applicants, the Sebastian Highlands private residential lot owners, and the North Indian River/South Brevard County Florida scrub-jay metapopulation, of which the affected Sebastian Florida scrub-jay subpopulations are a part. The Sebastian HCP will focus on restoring and managing, in the long-term, the oak scrub, scrubby flatwood, and mesic matrix habitat types occurring within the Scrub- Jay Habitat Compensation Areas to optimize habitat conditions for use by scrub-jays. Use of the habitat-based approach permits the Applicants to assess the demographic impacts of habitat destruction and habitat protection and management from a landscape or ecosystem perspective. It also serves to protect the broad range of native species associated with the Atlantic Coastal Ridge scrub ecosystem under the terms of the HCP and provides greater flexibility to the Applicants in dealing with future changed circumstances. 1 .1 . Purpose and Need of the Proposed Action The purpose of the Sebastian HCP is to: a. Provide for greater regulatory certainty to the Applicants and private residential lot owners within the platted residential subdivision of Sebastian Highlands in meeting the fast-growing social and economic needs of this residential community. 3 I I I I I I I I I I I I: I. I I 1 1 1 I This will be achieved by including gll of the platted residential lots within the Sebastian Highlands subdivision into the Sebastian HCP Plan Area for consideration of changes that are reasonably foreseen to potentially affect the functioning HCP. Using the habitat-based approach, the Sebastian HCP addresses the stochastic nature of Florida scrub-jay territories in response to changing demographic and environmental conditions. b. Protect the broad range of native species characteristic of the Atlantic Coastal Ridge scrub ecosystem. The beneficial attributes of this rare and vanishing ecosystem (Meyers 1 990) will be protected by implementing specific habitat restoration and management actions to return the combined 330.5:t: acre Scrub- Jay Habitat Compensation Areas to conditions representative of the historical landscape and thereby optimal for native species of conservation concern adapted to this fire-dependent, open landscape. For purposes of this HCP, the Florida scrub-jay will function as the indicator species to set habitat management goals within the Scrub- Jay Habitat Compensation Areas. c. Enhance the recovery potential of the North Indian River County/South Brevard County metapopulation, the fourth largest Florida scrub-jay metapopulation and most important metapopulation for species recovery along the Florida's Atlantic Coast (Breininger and Oddy 1998), by increasing the population persistence probability of the Sebastian scrub-jay subpopulations. This will be accomplished by restoring and maintaining optimal scrub- jay habitat conditions within the Scrub-Jay Habitat Compensation Areas, inclusive of the mesic flatwood dispersal corridors to be maintained on the Sebastian Airport properties. These corridors, as described above, will function to reduce the negative effects of habitat fragmentation by providing a vital open landscape linkage between the Sebastian scrub-jay subpopulations and the St. Sebastian River Buffer Reserve/South Brevard County core scrub-jay population. Thes.e dispersal corridors will also function to benefit other species of conservation concern moving through this area. Habitat loss and fragmentation, and the degradation of habitat quality as a result of fire exclusion, are the primary factors which endanger the long-term persistence of the Florida scrub-jay population occupying the Atlantic Coast Subregion {Breininger et al. 1996a; Stith et al. 1996; Fitzpatrick et a/. 1994a; Swain et al. 1995; Breininger 4 I I I I I I I I I I I I I I I I I I I and Oddy 1998). The Sebastian HCP is also designed to address these factors which currently threaten the persistence of the Sebastian Florida scrub-jay subpopulations. The FWS recognized, as early as 1991, that regulation of occupied scrub-jay habitat located within the 14,000:t platted one-quarter acre residential lots of the Sebastian Highlands subdivision on an individual lot-by-Iot basis results in increased fragmentation and degradation of suitable scrub-jay habitat' in this area due to small- scale mitigation resolution and absence of large-scale habitat management. In addition, this regulatory approach significantly encumbers the land use of multiple private lot owners by requiring procurement of individual HCPs prior to residential development. Remnant Atlantic Coastal scrub habitat remains in the Sebastian Highlands subdivision in severely fragmented patches within a highly developed suburban residential landscape matrix. The adverse influences of the expansive urbanization, including habitat loss, habitat fragmentation, and increased vulnerability to predation, on the demographic success of the Florida scrub-jay families persisting in the Sebastian Highlands subdivision are emphasized by the severe scrub-jay population decline documented in this area. Demographic studies of colorbanded scrub-jays in known territories conducted within the incorporated limits of the City of Sebastian, comprised primarily of the Sebastian Highlands residential subdivision, during the seven year period, 1991 to 1998, documented a 54% decline from 35 breeding pairs to 16 breeding pairs (Toland unpubl. data). Implementation of a functioning HCP that directs immediate and intensive habitat restoration and management of the remaining Atlantic Coastal scrub habitat patches is needed not only to ameliorate the severe Florida scrub-jay population decline, but also to relieve the regulatory burden from residential lot owners desiring to develop their properties. 1.2. Government Regulations Pertaining to the Sebastian HCP The Florida scrub-jay was federally listed as a threatened species on June 3, 1987. This Federal listing granted protection to the Florida scrub-jay in accordance with Section 4(d) and 9 of the ESA (16 USC 1531 -1543), and by regulations promulgated thereunder (50 CFR Part 17), which prohibit the "take" of a federally listed species. The Secretary of the Interior alld the FWS are primarily responsible for administratiop of the ESA. . "Take" is defined to mean harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or attempt to engage in any such conduct (Section 3(8) of the ESA). IIHarm" and "harass" have been further defined in FWS regulations 50 CFR 17.3. "Harm" is interpreted to include significant habitat modification or degradation which results in death or injury to listed species to such an extent as to significantly disrupt normal behavioral patterns which include, but are not limited to, breeding, 5 I 1 1 I 1 1 1 I I I' I I I I I I I I I feeding or sheltering. "Harass" is defined as an intentional or negligent act or omission which creates the likelihood of injury to wildlife by annoying it to such an extent as to significantly disrupt normal behavior patterns which include, but are not limited to, breeding, feeding or sheltering. Therefore, any activity as described above, may constitute a violation of Section 9 of the ESA. The Section 9 prohibitions against "take" apply to actions conducted by ".. .any person subject to the jurisdiction of the United States..". The term "person" was further interpreted in a 1988 amendment to the ESA to include actions carried out by states, counties and municipalities. This includes the issuance of land clearing and development permits by local governments, such as the City of Sebastian. The ESA provides two regulatory methods to the "person" who wishes to conduct development activities on land containing federally listed species. The regulatory method that is used is based on whether the project is a Federal activity or a non- Federal activity. Federal activities include, but are not limited to, the issuance of Federal permits, authorization, or funding. In either case, the permitted "take" of a listed species is referred to as an "incidental take". Incidental take is defined as any take of a listed species that results from, but is not the purpose of, carryin9 out an otherwise lawful activity (Section 1 0(a)(1 )(8), ESA). The first method for procurement of an "incidental take" authorization is for Federal activities. This is accomplished through Section 7 of the ESA, Interagency Cooperation, by issuance of an "incidental take statement" from the FWS. Section 7(a)(2) of the ESA requires that each Federal agency, in consultation with the FWS, insure that any action it authorizes, funds or carries out, is not likely to jeopardize the continued existence of any listed species or result in the destruction or adverse modification of habitat determined to be critical to such species. The second method, which addresses non-Federal activities such as the private development concerns addressed herein, is the issuance of an "incidental take" permit from the FWS in accordance with Section 1 0(a)(1 )(8) of the ESA. This method requires that the applicant submit a conservation plan, referred to as a Habitat Conservation Plan (HCP). The goal of the HCP program is to ensure that the effects of the authorized incidental take will be adequately minimized and mitigated to the maximum extent practicable (FWS and National Marine Fisheries Service [NMFS] 1996). The Congressional intent of the HCP program was to institute "... a process that, at its best, would integrate non-Federal development and land use activities with conservation. goals, resolve conflicts between endangered species protection ana economic activities on non-Federal lands, and create a climate of partnership and cooperation" (FWS and NMFS 1996). The Sebastian HCP, as presented herein, is designed to comply with the Congressional intent of the HCP program. The Florida scrub-jay is also protected in accordance with the Wildlife Code of the State of Florida (Chapter 39, Florida Administrative Code (F.A.C.)), administered by the Florida Fish and Wildlife Conservation Commission (FWC), formerly the Florida 6 I I I I I I I I I' I I I I, I I I I I I. Game and Fresh Water Fish Commission (FGFWFC), where it is listed as a threatened species. The State of Florida, in Chapter 39, F.A.C., defines take similarly to the ESA, except that protection of occupied habitat is not specifically included in the State's definition of "take". The FWC will be requested to provide comment to the Sebastian HCP as part of the public review process. In accordance with Section 10(a)(2)(A) of the ESA, this document assesses the effects of the proposed take on the Florida scrub-jay population and provides conservation strategies that serve to minimize and mitigate these potential adverse effects. 7 I I I I I I I I I I' I I I I I I, I I I 2.0 PROJECT DESCRIPTION/IMPACTS 2.1. Sebastian HCP Boundaries (HCP Plan Area) The Sebastian Highlands subdivision is located in the northernmost part of Indian River County, Florida, within the incorporated limits of the City of Sebastian. Figure 1 provides a Vicinity Map showing the location of the City of Sebastian and the expansive Sebastian Highlands subdivision. Sebastian Highlands is an active 14,000:f: lot residential subdivision platted in the 1950's by General Development Corporation (GDC), currently known as Atlantic Gulf Communities (AGC). The City of Sebastian experienced one of the highest rates of growth, 237%-337%, in the State of Florida between 1980 and 1990 (Fernald et a/. 1992). A rapid rate of growth continues in this municipality. The Sebastian HCP ITP impact area (ITP impact area) is defined by all platted residential lots located within the Sebastian Highlands subdivision. The ITP impact area is inclusive of the 317 one-quarter acre Sebastian Highlands lots (79.3:f: acres) currently recorded at the City of Sebastian's building department as designated by the FWS as potentially occupied by Florida scrub-jays. As a result of habitat enhancement actions to be implemented by the Applicants under this Sebastian HCP, the ITP impact area also includes the possibility of a future take of scrub-jays on the 88.1:f: acre Sebastian Airport commercial property owned by the City of Sebastian and on four (4) acres located along the southern boundary of the Pelican Island Elementary SctlOol grounds owned by the School Board. It is important to reiterate that the subject total 92:f: acres is currently not used by and is unsuitable for use by Florida scrub-jays. The ITP impact area and the Scrub-Jay Habitat Compensation Areas, as described below, define the project boundaries of the Sebastian HCP (HCP Plan Area). In accordance with the regulatory criteria set forth under section 10(a}(2}(A), a qualitative analysis of the potential adverse impacts of the proposed taking on the North Indian River/South Brevard County Florida scrub-jay metapopulation, of which the Sebastian Florida scrub-jay subpopulations are a part is presented herein. Steps to be taken by the Applicants to minimize and mitigate such impacts are also covered under this HCP. The combined 330.5:f: acre Scrub-Jay Habitat Compensation Areas are comprise,d of 324:f: acres of Florida scrub-jay potential habitat types (oak scrub, scrubby flatwoods, and mesic matrix habitat types), both occupied and unoccupied by scrub-jays, and the 6.5:t acre mesic flatwood Sebastian Airport dispersal corridor. The Scrub-Jay Habitat Compensation Areas are located on the following publicly-owned lands: 1.) the 406:f: acre North Sebastian Scrub Conservation Area, 2.) the 38.5:f: acre Sebastian Airport properties, 3.) the 10:1: acre Sebastian Highlands Scrub Conservation Area (34 Lots in Unit 17), 4.} the 11.9:t acre Pelican Island Elementary School scrub (located in Unit 17), and 5.) the 111:1: acre Wabasso 8 r_--- I I I I I I I I I Ii I I I I I Ii I I I Q~~(:r1 Ji~::, 1'-,' ,", -._ 'J..., \ ~:~J.

I I I I I I I I I I I I I I I Scrub Conservation Area. Total acreage of public lands within these conservation properties is 577.4:!: acres, of which 324:t acres support scrub that is occupied or through restoration can be colonized by scrub-jays. The 6.5:!: acres of mesic flatwoods to be managed at Sebastian Airport will provide a vital corridor for dispersing scrub-jays. As discussed in Section 4.1.3 below, the 330.5:!: acre Scrub-Jay Habitat Compensation Areas does not include the 34.6:t acre portion of the Wabasso Scrub Conservation Area that was previously used by Indian River County as compensatory mitigation for the take of one (1) Florida scrub-jay territory incidental to the construction of the County Road 512 improvements project (FWS Log No. 4- 1-96-432). . Figure 2 provides an overlay, on an 1994 high resolution orthophoto quad (OOQ), of the location of the 31 7 FWS designated potential scrub-jay habitat lots to be impacted in the Sebastian Highlands as part of the overall ITP impact area and the proposed Scrub-Jay Habitat Compensation Areas. This aerial display clearly reveals the expansive suburban nature of Sebastian Highlands subdivision and the severe habitat fragmentation that presently characterizes the Sebastian HCP Plan Area. An important fact that must be considered in determining the sufficiency of the proposed Sebastian HCP conservation initiative in meeting the regulatory requirements of section 10(a)(2)(A) of the ESA is that the proposed Scrub-Jay Habitat Compensation Areas represent the largest, most contiguous, and the best quality scrub-jay habitat parcels remaining in the HCP Plan Area. Some residential lots to be impacted in Unit 17 of Sebastian Highlands under this HCP are recognized to contain high quality scrub habitat; however, as clearly depicted on Figure 2, the remaining scrub is highly fragmented by developed residential lots and roads. In addition, the application of prescribed fire within the one-quarter acre lots, to manage optimal scrub-jay habitat conditions in the long-term, is not practicable within this existing high density residential landscape. Due to the fragmented landscape conditions presently characterizing the HCP Plan Area, the ability of the Applicants to "design" a scrub sanctuary that considers the biological criteria set forth by Fitzpatrick et al. (1 994a) for development of a functioning Florida scrub-jay reserve (e.g. considerations of connectivity, geographic distribution, habitat quality, management potential, etc.,) was not an option. However, the Scrub-Jay Habitat Compensation Areas currently owned b"y Indian River County: the North Sebastian Conservation Area, Wabasso Scrub Conservation Area, and Sebastian Highlands Scrub Conservation Area (Unit 17 - 34 lots), were each acquired by this local government at the recommendation of the FWS based on the 1 996 scrub-jay core habitat reserve design developed by this Federal agency (Toland 1996). The referenced properties were designated by the 1 996 FWS reserve design as core habitat conservation areas essential to the long- 10 r--- I I I , II I I I I I, I, I I: I I I I, I I I term persistence of Sebastian scrub-jay subpopulations (Toland 1996) (see discussion in Section 3.1 below). Based on a summer/fall 1998 survey conducted in support of this HCP, the Sebastian Florida scrub-jay population was determined to consist of two (2) subpopulations, referenced herein as the north sub population and the south subpopulation. These subpopulations were defined using criteria set forth in Fitzpatrick et al. (1994a) and Stith et al. (1996) to describe the spatial structure of Florida scrub-jay populations using data on geographic distribution and natal dispersal distances. "Subpopulations" are separated by gaps of 2.2 miles (3.5 km). This distance represents the maximum dispersal distance for 80% of all dispersals at Archbold Biological Station. The south subpopulation is comprised of a total of 9, and potentially, 10 scrub-jay families. These southern families are primarily located in Units 10 and 17 of the Sebastian Highlands subdivision (seven (7) families), and the Wabasso Scrub Conservation Area two (2), possibly three (3), families). The north subpopulation consists of a total of four (4) scrub-jay families, three (3) families in the North Sebastian Conservation Area and one (1) family within the extreme western portion of the Sebastian Airport properties covered under this HCP (Carroll and Associates 1997). These 13 to 14 scrub-jay families comprise the Sebastian HCP study population (study population). It should be noted that an additional five (5) scrub-jay families are documented to occupy.habitat on and adjoining the Sebastian Golf Course and the Sebastian Elementary School properties (Toland unpubl. data). These properties are not included within the Sebastian HCP Plan Area. These families are part of the north subpopulation and should greatly benefit from habitat conservation actions proposed under this Sebastian HCP. The study population is part of the fourth most important metapopulation of the species (study metapopulation) (Breininger and Oddy 1998). Stith et al. (1996) described "metapopulations" as populations that are separated by 7.5 miles (12 km), representing the maximum dispersal distance of more than 99% of all dispersals at Archbold. Most of this fourth largest metapopulation occurs in south Brevard County, although at least 12 pairs occur on the St. Sebastian River State Buffer ReseNe (SBR) and on the adjoining Carson Platt Estate Property located in Indian River County (Breininger and Oddy 1998). The Carson Platt Estate Property will be added to the SBR in the immediate future. The families on Carson Platt have never been surveyed and scrLlb-jay sUNeys on the Coraci section of the SBR hav.e only recently. been initiated (Breininger pers comm.). These pairs do not appear on the statewide sUNey because of previous access permission problems (Breininger pers comm.). Observations of historical and recent aerial photography indicate that with extensive restoration these areas could support dozens of Florida scrub-jay pairs (Breininger pers comm.). If all public lands proposed or acquired are restored, the total size of this regionally important metapopulation could approach 140 pairs (Breininger and Oddy 1998). 12 I I I I I I I I I I I I I I I I I I I conditions along the Atlantic Coastal Ridge ecosystem in North Indian River County are consistent with the habitat requirements of other native species that use this unique ecosystem (Schmalzer et al. 1994, 1999; references in Breininger and Oddy 1998; Fitzpatrick et al. 1994a). Studies conducted by the FWS in support of the South Florida Multi-Species Recovery Plan (USFWS 1999, USFWS unpubl. data) determined that federally listed plant species do not occur within the Sebastian HCP Plan Area. Therefore, federally listed plants are not addressed under this HCP. 2.4.1 Biological Overview of the Florida Scrub-Jay Descriotion The Florida scrub-jay is a 2.5 to 3-ounce, 12-inch-long, blue and gray crestless jay that is endemic to peninsular Florida (Woolfenden and Fitzpatrick 1984). It is the only bird species that is endemic to peninsular Florida (Fitzpatrick et al. 1994a). In the adult plumage, a necklace of blue feathers separates the whiter throat from the gray underparts and a white superciliary line or eyebrow often blends into a whitish forehead. The back is gray and the tail is long and loose in appearance (Fernald and Toland 1991). Juvenile scrub-jays less than about five (5) months of age can be identified by their dusky brown head and neck and shorter tail (Woolfenden and Fitzpatrick 1984). In late summer and early fall, immature scrub-jays undergo a partial molt of body feathers that renders them indistinguishable from adults in the field (Woolfenden and Fitzpatrick 1984). Adult male and female Florida scrub-jays are not distinguishable by plumage, but are differentiated by a distinct "hiccup" call vocalized only by females (Woolfenden and Fitzpatrick 1986). Florida scrub-jays are generally associated with Florida's unique scrub habitat, a fire-maintained ecosystem dominated by evergreen oaks (Quercus spp.) typically occurring on the sandy well-drained soils of relict coastal and inland dune systems geographically unique to peninsular Florida (Woolfenden and Fitzpatrick 1984; Myers 1990; Fitzpatrick et al. 1991; Fernald and Toland 1991). The restriction of Florida's oak scrub communities to well-drained sandy soils results in a habitat type that naturally occurs as patches of scrub oak within a matrix of mesic shrub communities on poorly-drained soils (Woolfenden and Fitzpatrick 1984, 1991; Myers 1990; Bergen 1994; Breininger et al. 1995, 1996b; Breininger and Oddy 1 998). The occurrence of scrub on high, dry lands has precipitated the wide-spread loss of this geographically limited habitat type to commercial/residential development and to agricultural conversion (FNAI 1990; Fernald 1989; Fitzpatrick et al. 1991). Due to this wide-spread loss of Florida's scrub habitat, FNAI (1 990) has ranked this natural community as imperiled, both globally and within the State of Florida. In response to the extreme environmental conditions and limited spatial extent of the scrub natural community, the Florida scrub-jay has evolved into a habitat specialist 15 I I I I I I I I I I I I I 'I I I I I I that has adapted by developing a unique social system that includes permanent monogamy, year-round territoriality, cooperative breeding, an intrafamilial dominance hierarchy, delayed dispersal, food caching, and an exceptional sentinel system (Woolfenden and Fitzpatrick 1977; Stallcup and Woolfenden 1978; Woolfenden and Fitzpatrick 1984). The Florida scrub-jay is non-migratory and occupies permanent year-round territories averaging 22.5 acres in size (Woolfenden and Fitzpatrick 1984; Fitzpatrick et al. 1991; Fitzpatrick et al. 1 994a). This species is one of the few cooperative breeding birds in the Eastern United States, whereby surviving fledgling scrub-jays usually remain with the breeding pair in their natal territory as "helpers," forming a closely-knit, cooperative family group (Stallcup and Woolfenden 1978; Woolfenden and Fitzpatrick 1984). Group size ranges from two (2) to eight (8) birds, but pre-breeding families average 2.8 individuals (usually a pair with from 0 to 2 helpers) (Fitzpatrick et al. 1 994a). Helpers participate in scanning for predators, territorial defense against neighboring scrub-jay groups, predator-mobbing, and the feeding of both nestlings and fledglings (Woolfenden and Fitzpatrick 1984). Distribution Florida scrub-jays were historically distributed throughout the Florida peninsula in suitable habitat in 39 of the 40 counties south of, and including, Levy, Gilchrist, Alachua, Clay, and Duval (Fitzpatrick et al. 1994a). The only county on the peninsula that historically lacked scrub-jays was Monroe (Fitzpatrick et al. 1 994a). Currently, the much-reduced range of the Florida scrub-jay extends from Flagler to Palm Beach counties on the Atlantic Coast (Fitzpatrick et al. 1994a). On the Gulf Coast, scrub-jays persist in small and distantly isolated populations from Levy south to Collier counties (Fitzpatrick et al. 1994a). In interior Florida, this species persists mainly on federal properties in Putnam and Marion counties south to Polk, Highlands, and Glades counties (Fitzpatrick et al. 1 994a). The present day Florida scrub-jay population is distributed within five (5) "Subregions", with well over half of the State's remaining jays occurring in three (3) core populations with at least 400 breeding pairs each (Fitzpatrick et al. 1 994a). These core population centers are associated with the Atlantic Coastal Ridge (Merritt IslandlCape Canaveral), the Mount Dora Ridge (Ocala National Forest), and the Lake Wales Ridge and associated ridges. These extensive scrub ridges constitute major Subregions within the overall distribution of Florida scrub- jay: the Atlantic Coast Subregion, the Ocala Subregion, and the Lake Wales Ridg.e Subregion (Fitzpatrick et al. 1 994a). Soil maps indicate that even prior to habitat modification by humans, these three (3) major Subregions were separated from one another by habitat types that were mostly unsuitable for use by scrub-jays (Fitzpatrick et al. 1994a). Today, these gaps have expanded due to encroaching citrus groves and burgeoning residential developments (Fitzpatrick et al. 1994a, 1 994b). 16 I I I I I I I I I Ii I I; I , I I I I I I, I The remaining two (2) Subregions are the Northern Gulf Coast Subregion and the Southern Gulf Coast Subregion (Fitzpatrick et at. 1994a). Historical records of Florida scrub-jay sightings and the distribution of sandy soils indicate that the Gulf Coast populations extending from Levy County south to Lee County originally comprised a fourth major contiguous population of scrub-jays (Fitzpatrick et at. 1994a). However, due to the extensive loss of habitat along the Gulf Coast, this once contiguous population has been functionally separated into the two (2) Subregions defined above (Fitzpatrick et at. 1994a). Habitat Suitabilitv The most abundant and conspicuous plant indicators of scrub habitats are four (4) species of shrubby, stunted, sclerophyllous-Ieaved oaks: Quercus geminata, Q. chapmani/~ Q. myrtifo/ia, and Q. inopina (Woolfenden and Fitzpatrick 1984; Myers 1990; Schmalzer and Hinkle 1 992; Fitzpatrick et at. 1994a). Most scrub plants are endemic to Florida, and are adapted to nutrient-poor soils, periodic drought, seasonally high rainfall, and frequent fires (Abrahamson 1984; Fitzpatrick et at. 1 994a). Optimal Florida scrub-jay habitat (Fitzpatrick et at. 1991; Breininger 1992; Breininger et at. 1995, 1996b) occurs as patches of oak scrub (focal habitat), embedded within a low and open mesic shrub landscape (matrix habitats) (Breininger et at. 1996b). Optimal oak scrub focal habitat exhibits the following characteristics: 1.) greater than 50% of the shrub layer comprised of scrub oaks (Quercus spp.), 2.) 10%-30% of the area comprised of open space (bare sand or sparse herbaceous vegetation); 3.) 0% to 15% pine canopy cover; 4.) a shrub height of 3.9 to 5.6' (1.2 to 1.7 m) without patches of tall scrub 5.6' (1. 7m) comprising areas larger than 1 acre (0.4 ha); and 5.) > 328' (100m) from a forest (Breininger et at. 1995, 1 996b). A forest is defined as an area exhibiting a canopy closure of > 65% (Breininger et at. 1995, 1996b). The essential elements of optimal Florida scrub-jay habitat are: the presence of scrub oaks, numerous patchy open spaces, an open pine canopy, and low shrub landscape structure. Native matrix habitats, principally scrubby and mesic pine flatwoods, and swale and depression marshes, are important components of optimal Florida scrub-jay habitat landscapes (Breininger et at. 1995, 1996b). These native matrix habitats provide prey species for Florida scrub-jays and habitat for other species of conservation conce~n (Breininger et at. 1995, 1996b). The high flammability of the native matrix habitats often serves to spread fire into the fire-resistant oak scrub habitats (Breininger et at. 1995, 1996b). The matrix habitats also provide habitat to Florida scrub-jays during periods of habitat degradation of the preferred oak scrub habitat (Breininger and Oddy 1998) . Long-term studies at Kennedy Sp,ace Center (KSC), located on Merritt Island, Brevard County, Florida, found that scrUb-jays occupy a broad range of habitat conditions, 17 Ii I I I I I I Ii Ii 11 I I I I, I I, I I I including areas that are marginal for them (Schmalzer et al. 1994). However, demographic success studies at KSC suggest that mortality exceeds reproductive success in areas on KSC that do not exhibit optimal scrub-jay habitat conditions, as described by Woolfenden and Fitzpatrick (1984), Fitzpatrick et al. (1991), and Breininger 1992 (Schmalzer et al. 1994). The open canopy and low shrub community structure of optimal scrub-jay habitat landscapes enhance habitat defendability as it provides the perched scrub-jay with a full view of its territory and an unobstructed flight path for the rapid defense of territorial boundaries (Woolfenden and Fitzpatrick 1984). The low, open vegetative community structure of preferred scrub-jay habitat also allows for effective surveillance of both aerial and ground predators (Woolfenden and Fitzpatrick 1 984). Predation, particularly by hawks, is the primary cause of Florida scrub-jay mortality (Woolfenden and Fitzpatrick 1984). Florida scrub-jays residing in large landscapes surrounded by other scrub-jay families are safer from predation than isolated families living in fragmented edge habitats due to the early warning system that is provided by the contiguous families (Breininger et al. 1996b). Maintenance of an open habitat landscape structure also enhances population persistence as it provides an opportunity for nonbreeders to detect vacancies in their surroundings and disperse into these areas with reduced chance of predation from woodland hawks (Breininger et al. 1 996a). The effectiveness of the scrub-jays' important territorial defense and predator surveillance behavior is significantly reduced in tall, disturbed scrub and wooded matrix habitats (Fitzpatrick et al. 1991; Breininger et al. 1991, 1995, 1996b). The increased presence of avian competitors within tall, overgrown or wooded habitats and the reduction in the visual range of the sentinel, which exposes the scrub-jay group to surprise attacks by aerial predators, such as hawks, are factors which reduce habitat quality (Breininger et al. 1991, 1995). Adult mortality is high and reproductive success is low for scrub-jay groups residing within tall, disturbed habitat types (Woolfenden and Fitzpatrick 1984; Fitzpatrick et al. 1991; Schmalzer et al. 1994). Fragmentation of native habitats and replacement with urban habitats increases the densities and hunting efficacy of nest predators such as fish crows (Corvus ossifragus), raccoons (Procyon 10 tor) , and house cats (Felis catus) that are much less common in optimal xeric oak scrub habitat (Breininger 1999). Fragmented anp urbanized landscapes also increase the numbers of potential competitors like the blue jay (Cyanocitta cristata) (Fitzpatrick et al. 1991; Breininger 1999). The intervening landscape matrix affects scrub-jay dispersal behavior (Fitzpatrick et al. 1994a). Protected scrub habitats most effectively sustain scrub-jay subpopulations if they are located within a matrix of surrounding habitats that can be safely negotiated by dispersing scrub-jays (Fitzpatrick et al. 1994a). Brushy pastures, scrubby corridors along railway and country road right-of-ways, and open 18 I I I I I I I I I I I I I I I I I I I habitat types allow for foraging and provides links for colonization among scrub-jay subpopulations (Fitzpatrick et at. 1994a). Expansive bodies of water, dense forest, urban development, suburban residential areas, shopping malls, major highways, and treeless, wide-open pastures inhibit dispersal movement of scrub-jays (Fitzpatrick et at. 1994a). Scrub - A Fire-Adaoted Natural Community The vegetative composition and structural features characterizing optimal Florida scrub-jay focal habitat, as defined above, represent native oak scrub habitat conditions; conditions which are created and maintained by periodic, high intensity fires (Myers 1990; Breininger et at. 1995, 199Gb). The fire regime in scrub habitat types is extremely variable (Myers 1990; Adrain and Farinetti 1995). It is dependent upon both the productivity (rate of fuel accumulation) of the scrub site and the surrounding matrix habitats (Myers 1990; Adrain and Farinetti 1995). Accumulation of fuels is slower in oak dominated scrub occurring on well-drained, infertile soils of the sand ridges (Myers 1990). In addition, the horizontal distribution of fuels in oak scrub on sand ridges is patchy due to the presence of numerous openings of bare sand which characterize this scrub habitat type. These factors result in a fire- dependent habitat type that is not very flammable and does not ignite easily (Myers 1990). Therefore, fires that burn into oak scrub habitat patches are generally ignited in the surrounding matrix habitats, such as pine flatwoods, occurring on poorly drained, fertile soils, which possess and rapidly accumulate continuous fine surface fuels (Myers 1990; Adrian and Farinetti 1995). When fires do occur in the scrub landscape, it usually results in a complex mosaic of slightly burned, intensely burned, and unburned area types (Myers 1990). This patchy burn effect is important as the presence of scrub habitat in various stages of development enhances habitat diversity and reduces potential adverse effects of the fire to dependent species with special habitat requirements (Myers 1 990). Because scrub is a pyrogenic ecosystem, its flora and fauna have developed adaptations to fire and are dependent on periodic fires to provide for the low, open scrub in which they have evolved (Myers 1990; Schmalzer et a/ 1994). One of the adaptations of Florida scrub-jays to frequent fires is the establishment and defense of large territories. "Ownership" of a large territory increases the scrub-jay group's probability of free access to enough habitat patches in optimal condition (Woolfenden and Fitzpatrick 1984). Fire. influences vegetative community composition and structure through its frequency and/or intensity (Myers 1 990). Scrub oaks, saw palmetto, and ericaceous shrubs regenerate from fire primarily by sprouting, and recovery is rapid (Schmalzer and Hinkle 1991). Species composition and richness change little (Schmalzer et at. 1994). The quality of an oak scrub patch for use by scrub-jays is a factor of time since fire (Breininger et a/. 1 996b). The suppression of fire within scrub habitats can result in a dense and overgrown vegetative structure, a condition that effectively decreases scrub-jay habitat suitability {Cox 1984; 19 I I I I Ii I I I I I I I I I I I I I I Woolfenden and Fitzpatrick 1984; Schmalzer et al. 1994; Myers 1990; Breininger et al. 1995, 1996a, 1996b; Breininger and Oddy 1998; Breininger 1999). Reoroduction and Demograohv Age at first breeding in the Florida scrub-jay ranges from one (1) to seven (7) years, with most individuals becoming breeders between the ages of two (2) and four (4) years (Woolfenden and Fitzpatrick 19911. Male scrub-jays become breeders later in life than females (Woolfenden and Fitzpatrick 1991). Nesting is synchronous, normally ranging from March 1 through June 30 (Woolfenden and Fitzpatrick 1990, Fitzpatrick et al. 1994a). However, in the Treasure Coast Region of Florida, persistent renesting attempts after nesting failures, and double brooding after successful nesting by as much as 20% of the breeding pairs, may extend the nesting season through the end of July (Toland unpubl. datal. Scrub-jays typically build their nests in Shrubby oaks, 3.2 to 6.4' (1 to 2 m) in height. Preferred nesting sites are Quercus inopina on the Lake Wales Ridge (Woolfenden and Fitzpatrick 1984) and Quercus myrtifolia on the Atlantic Coastal Ridge (Toland 1991). Florida scrub-jay clutches usually contain three (31 or four (41 eggs, are incubated for 17 to 18 days, and fledging occurs 16 to 19 days after hatching (Woolfenden 1974, 1978; Fitzpatrick et al. 1994a). Only the breeding female incubates and broods eggs and nestlings (Woolfenden and Fitzpatrick 19841. During incubation, breeding males are often conspicuous on sentinel perches within 165' (50m) of the nest (Toland unpubl. data). Mean annual productivity for stable populations of scrub-jays is 2 fledglings per pair per year (Woolfenden and Fitzpatrick 1990; Fitzpatrick et al. 1994a) and the presence of helpers improves fledging success (Mumme 1993). Fledglings remain dependent upon adults for food for eight (8) to 10 weeks after leaving the nest (Woolfenden 1975; McGowan and Woolfenden 1 990). Nesting failures are nearly always caused by predation, most frequently by ground-based predators including snakes, raccoons, and domestic cats (Schaub et al. 1992; Toland unpubl. data; Breininger unpubl. data). Recruitment of new scrub-jay territories generally occurs when the dominant male helper acquires both a mate and a portion of his natal territory through a process termed territorial budding (Fitzpatrick et al. 1991). Florida scrub-jays may also obtain a breeding space when an established territory is vacated due to death of one or both of the established breeders or, more rarely, family breakups (Fitzpatrick et al. 199~; Breininger ef. al. 1 996b). Although the dispersal distance of Florida scrub-jays is directly related to the surrounding habitat types and intervening landscape features, most Florida scrub-jays pairs establish territories within one (1) to three (3) territories (984' [300m] to 3281' [1 OOOm]) of their natal ground (Breininger et al. 1 995). In suitable habitat, more than 95 % of all observed scrub-jay dispersals are two (2) miles (3.2 km) or less in distance and rarely do they exceed five (5) miles (8 km) (Fitzpatrick et al. 1 994a). All dOGumented scrub-jay dispersals exceeding five (5) miles 20 I I I I I I I I I I I I I I I I I I I have been across unsuitable habitat conditions, including suburban residential communities, pastures, and woodlands (Fitzpatrick et a/. 1994a). Predators and the Sentinel System Predators on adult Florida scrub-jays are relatively few, with the exception of falconid and accipitrid raptors. House cats and bobcats (Fe/is rufus) have been documented to prey on adult scrub-jays (Fitzpatrick et a/. 1994a). Eastern coach whips (Masticophis flagellum), Eastern indigo snakes (Drymarchon corais coupertl, and great horned owls (Bubo virginianus) occasionally prey on adult scrub-jays (Fitzpatrick et a/. 1994a). However, the most dangerous native predators to scrub- jays are the Cooper's hawk (Accipiter cooperill, sharp-shinned hawk (A. striatus), merlin (Falco co/umbarius), northern harrier (Circus cyaneus), and peregrine falcon (F. peregrinus) (Breininger et a/. 1995, 1996a, 1996b; Fitzpatrick et a/. 1994a; McGowan and Woolfenden 1989). In response to foraging efficiency of these raptors, Florida scrub-jays have evolved a well-developed sentinel system (McGowan and Woolfenden 1989). Individuals within a family group take turns occupying an exposed perch above the oak shrubs scanning for predators. When a raptor is spotted nearby, the sentinel jay gives a distinctive warning call and all group members dive for cover in the nearest dense vegetation. Food Habits and Caching Florida scrub-jays forage mostly on or near the ground, often along the edges of natural or man-made openings. Animal food items consist primarily of terrestrial arthropods (Woolfenden and Fitzpatrick 1984; Fernald and Toland 1991; King et a/. 1992). Vertebrate prey items comprise the minority of the diet, but may include a wide array of species weighing up to one (1) ounce (more than 1/3 the body weight of a scrub-jay), including treefrogs, lizards, snakes, nestling birds, and mice (Toland unpubl. data; King et a/. 1992). Acorns are extremely important in the diet of Florida-scrub jays from August through November. During this time, scrub-jays harvest and cache thousands of scrub oak acorns throughout their territory. Each scrub-jay may cache 6,000 to 8,000 acorns per year (DeGange et a/. 1989). Acorns are typically buried beneat.h the surface of the sand in openings in the scrub during fall, and retrieved and consumed in winter and early spring. Scrub-jays on the Atlantic Coastal Ridge frequently cache acorns in pine trees (Pinus spp.) at heights of from 1 to 30 feet (0.3 to 9m), usually in forks of branches, distal pine boughs, under bark, or on epiphytes (Toland unpubl. data). 21 I I I I I I I I I I I I I I I I I I I Scrub Habitat Loss and Florida Scrub-Jay Pooulation Decline Scrub habitats associated with Florida's barrier islands, mainland coasts, Ten Mile Ridge, and Lake Wales Ridge are some of the most imperiled natural communities in the United States, with estimates of habitat loss since pre-settlement times ranging from 70% to more than 85% (Bergen 1994; Fitzpatrick et al. 1994a). The most important and pervasive causes of scrub habitat loss are commercial/residential development and agricultural conversion (Fernald 1989; Fitzpatrick et al. 1991, 1 994a). Much of the remaining parcels of scrub are fragmented and in various states of degradation due primarily to widespread fire suppression (Fernald 1989; Fitzpatrick et al. 1994a; Breininger et al. 1996a, 1996b; Breininger and Oddy 1998; Breininger 1999). Statewide Florida scrub-jay population trends have closely mirrored scrub habitat loss; the present-day population is no more than 15% of the pre-settlement population estimate (Fitzpatrick et al. 1994a). The most precipitous scrub-jay population decline occurred during the 1980's and 1990's with an estimated 25% to 50% reduction in scrub-jay numbers (Fitzpatrick et al. 1994a, 1994b; Toland unpubl. data; Breininger and Oddy 1998; FWS 1999). Florida scrub-jays are presently functionally or completely extirpated from 10 of 39 counties historically occupied by scrub-jays, including Alachua, Broward, Clay, Dade, Duval, Gilchrist, Hendry, Hernando, Pinellas, and St. Johns Counties (Fitzpatrick et al. 1994a, 1994b). As of 1994, half of all remaining Florida scrub- jays occurred in Brevard County (1,232 families) and Highlands County (890 families) (Fitzpatrick et al. 1 994a). A total of 19 counties contained 30 or fewer breeding pairs of scrub-jays, 'Of which the majority of these counties would have historically supported hundreds to thousands of scrub-jay families (Fitzpatrick et al. 1994a, 1994b). The Florida scrub-jay was censused across its entire range during 1 992-93 in an effort to determine its statewide distribution and population status (Fitzpatrick et al. 1994b). This study documented about 4,000 breeding pairs of Florida scrub-jays, with approximately 2/3 of the population inhabiting non-Federal lands (Fitzpatrick et al. 1994b). Extrapolating from average scrub-jay group size (2.8) resulted in an estimate of about 11,000 Florida scrub-jays as of 1993 (Fitzpatrick et al. 1994b). Cox (1987) estimated that 15,400 to 22,800 jays comprised the statewide Florida scrub-jay population as of 1984. This estimate is thought to be conservative as Cox is suspected of missing a substantial number of smaller scrub-jeW subpopulations and isolated family groups (Fitzpatrick et al. 1994b). The statewide census documented 52 breeding pairs of scrub-jays in Indian River County (Toland 1993; Fitzpatrick et al. 1994b). Subpopulations within the Atlantic Coastal Subregion were monitored from 1988 through the present at Sebastian (Toland unpubl. data), Merritt Island (Breininger et al. 1995), Valkaria (Toland unpubl data; Breininger and Oddy 1998), the southern Brevard County mainland (Breininger and Oddy 1998) and southern Brevard County barrier island (Breininger 22 I I I I I I I I I I I I I I I I I I I 1999). These studies document a 10-year decline of at least 50% in the Atlantic Coastal Ridge scrub-jay population. Scrub-Jays in Residential Landscaoes The habitat structure and landscape matrix used by Florida scrub-jays residing in residential landscapes differs significantly from native scrub habitat conditions (Fitzpatrick et a/. 1994a; Thaxton and Hingtgen 1996; Breininger 1999; Toland unpubl. data). As residential build-out occurs, suitable scrub-jay habitat patches become smaller and increasingly isolated from neighboring patches (Fitzpatrick et a/. 1 994a). Within highly fragmented residential landscapes, such as that exemplified by the Sebastian Highlands ITP impact area (see Figure 2), demographic success of the population decreases (Fitzpatrick et at. 1994a; Thaxton and Hingtgen 1996; Breininger 1999; Toland unpubl. data). The habitat quality of the isolated scrub patches declines due primarily to fire exclusion and the introduction of ornamental landscape and exotic plants (Fitzpatrick et at. 1994a; Breininger 1 999). Predation from domestic animals (house cats) and urban-adapted avian competitors, blue-jays and fish crows, increases mortality rates of scrub-jays within the fragmented residential landscape (Breininger 1999; Fitzpatrick et at. 1994a). In addition, nonbreeding scrub-jays are forced to disperse greater distances through hostile landscapes, exposing the dispersing individual to increased predation and vehicular collisions (Fitzpatrick et a/. 1994a; Thaxton and Hingtgen 1996; Breininger 1999, Toland unpubl. data). All suburban scrub-jay populations studied are declining because of poor demographic success. (Toland 1991; Fitzpatrick et a/. 1994a; Thaxton and Hingtgen 1996; Breininger 1999). . It is interesting to note that scrub-jays residing in residential landscapes appear to initially benefit from development; population densities are reported to increase in lightly developed suburban areas where many patches of scrub remain and build- out is 33% or less (FWS 1999; Toland unpubl. data). This is probably a response to supplemental food sources (feeders) (Fitzpatrick et a/. 1994a), creation of openings in the scrub, and visual buffers (buildings) between neighboring jay families (Toland, pers. observ.). However, as human development escalates towards complete build-out, the increased risk of predation decreases survival potential of fledgling jays and successful nesting attempts (Toland 1991; Bowman unpubl. data; Breininger 1999). Because adult scrub-jays are relatively long-lived, resident pairs often persist for years in some of the most densely human-populated Florid.a suburbs (Fitzpatrick et a/. 1994a). Although these suburban jays often continue to nest, they incur high nest failure rates (Toland 1991; Fitzpatrick et at. 1994a). In fragmented residential landscapes, scrub-jays disperse earlier and become breeders at younger ages than scrub-jays in contiguous native scrub systems (Toland unpubl. data; Breininger 1999). Many females and some males disperse during their first year in contrast to delayed dispersal in native habitats (Breininger 1 999). Nesting in suburban habitats starts earlier and ends later than in native 23 I I I I I I I I I I I I I I I I I I I scrub, with much higher renesting attempts (three (3) to four (4)) and double brooding (20%) than in native habitats (Fitzpatrick et al. 1994a; Toland unpubl. data). The loss of native scrub plants and introduction of ornamental vegetation alters the predominant shrub species in disturbed sites, causing more variation in scrub-jay nest sites than in natural habitats. In intensively developed suburbia, scrub-jays often nest higher than in native scrub and almost exclusively in non- native shrubs and trees (Fitzpatrick et al. 1 994a). In large, natural habitats, Florida scrub-jays generally retain their territories and attract new replacement mates following the death of their spouse (Woolfenden and Fitzpatrick 1984; Breininger et al. 1996b). In fragmented populations, females frequently disperse, often for long distances, after the death of a mate until they find an available male in another habitat patch (Breininger 19991. Conversely, Breininger (1999) found that dispersals by males within fragmented residential landscapes are limited to nearby clusters where they become nonbreeders until a breeding vacancy becomes available in the cluster of their residence. Breininger (1999) found that males represent the limiting sex in a cluster even when the total population had fewer females. Thaxton and Hingtgen (1996) reported that scrub-jays usually moved from small suburban scrub fragments into larger tracts of scrub and not from large tracts into smaller fragments. Once extinction occurred within the suburban scrub fragment the potential for recolonization of the abandoned habitat fragment by scrub-jays from larger tracts is low (Breininger 1999). Dispersals by either sex may be limited across fragmented residential landscapes if extinction occurs in intervening fragments, as dispersing scrub-jays may be influenced by the presence of other scrub-jays and not just the availability of scrub habitat (Stith et al. 1 996). The value of maintaining scrub-jays in suburban habitat fragments is that they may be an important source, although temporary, of individuals to colonize unoccupied, potential scrub-jay habitat areas following restoration to suitable habitat conditions (Breininger 1999). These above findings have several conservation management implications: 1.) where possible, scrub-jay reserves should be close together (within about one (1) mile [1.6 km]) to accommodate the low dispersal tendencies of males (Breininger 1999); 2.) scrub habitat patches within the suburban residential matrix must be managed for optimal scrub-jay habitat conditions to maximize demographic succes.s within the patch (Fitzpatrick et al. 1994a; Breininger 1999), and 3.) scrub fragments should be maintained no more than 2.6 miles (4.2 km) to facilitate the dispersal of females across the suburban landscape (Breininger 1999). The contribution of scrub-jay clusters residing in suburban/urban fragments to the long- term population size of their associated metapopulation is expected to be minimal because of the poor demographic success exhibited by these fragmented clusters (Breininger 1999). 24 I I I I I I I I I I I I I I I I I I I Modeling of Pooulations and Metaoooulations The Florida scrub-jay has been the subject of rigorous time-specific probability of persistence models (Fitzpatrick et a/. 1991; Woolfenden and Fitzpatrick 1991; references in Breininger et al. 1996b; Fitzpatrick et a/. 1994a). These demographic models suggest that populations of at least 400 territories have a 99% probability of survival for 100 years and are referred to as "core" populations (Fitzpatrick et al. 1994a). "Satellite" populations are composed of at least 100 breeding pairs of scrub-jays and have an 85 to 90% probability of survival for 100 years (Fitzpatrick et a/. 1994a). A subpopulation with less than 10 breeding pairs has about a 50% probability of extinction within 100 years (Fitzpatrick et al. 1991; Fitzpatrick et al. 1994a; Stith et al. 1996). Florida scrub-jays generally disperse up to two (2) miles with normal maximum dispersals ranging up to five (5) miles in suitable habitat (Fitzpatrick et a/. 1994a). Thus, breeding territories within about two (2) miles of one another are considered part of the same population or sub population (Stith et al. 1 996; Fitzpatrick et al. 1 994a). A metapopulation is comprised of a group of interbreeding subpopulations that are separated from one another by no more than 7.5 miles (Stith et al. 1996). Small subpopulations of jays are less likely to go extinct if located within the normal two (2) mile dispersal radius of neighboring scrub-jay subpopulations (Woolfenden and Fitzpatrick 1991; Fitzpatrick et al. 1994a). Population modeling suggests that a strong correlation exists between habitat quality and scrub-jay population extinction risk (Breininger et al. 1999). Habitat models predict population declines of 25 % every five years in large unburned tracts (Breininger et al. 1996b). Population modeling suggest that scrub-jay population increases after restoration to optimal habitat will be slow. These relationships suggest that scrub restoration activities should be prioritized in, areas that have scrub-jays remaining or are proximal to scrub-jay sub populations at risk (Breininger et a/. 1999). This conclusion is based on slow population responses expected in unoccupied areas and the severe declines occurring in existing populations attributed to infrequent burning. Although local populations of scrub-jays have become extremely small in many areas, probabilities of extirpation remain predominantly affected by habitat loss, habitat degradation through fire suppression, and stochastic influences o.n population dynamics (Woolfenden and Fitzpatrick 1984; Fitzpatrick et a/. 1994a). In addition, the Florida scrub-jay has a sedentary social system that naturally creates small effective population sizes and increased levels of inbreeding (Woolfenden and Fitzpatrick 1984). Although matings between immediate family members are rare, matings between first-cousins, second-cousins, and other close relatives are quite common, even in large, contiguous populations (Woolfenden and Fitzpatrick 1978). For these reasons, the species exhibits reduced genetic variability compared to the western scrub-jay (Aphelocoma californicus) and other 25 I I I I I I I I I I I I I I I I I I I congeners (Peterson 1 990). Numerous subpopulations as small as 15 breeding pairs, have survived since pre- settlement times despite being isolated by natural physiographic conditions (Fitzpatrick et al. 1994a). Therefore, it is doubtful that increased inbreeding resulting from present day reductions in Florida scrub-jay subpopulation sizes will significantly affect survival potential to the same magnitude as would ecological and demographic factors (Lande 1988; Simberloff 1988; Fitzpatrick et al 1994a). Habitat loss and unnatural succession resulting from fire suppression are factors that will most likely precipitate extinction of the Florida scrub-jay (Fitzpatrick et al. 1994a; Breininger and Oddy 1998). 26 I I I I I I I I I I I I I I I I I I I 3.0 HCP PLAN AREA BASELINE INFORMATION 3.1 FWS Consultation History and Existing Data for Sebastian Highlands Scrub- Jay Habitat Lots The FWS consultation history and existing data for the Florida scrub-jay subpopulations residing within the HCP Plan Area are primarily recorded in correspondence between the FWS, the City of Sebastian, and Indian River County. The conflict between residential development and conservation of the Florida scrub- jay has been a predominant issue in the City of Sebastian from 1991 to the present. The number and location of the privately-owned platted Sebastian Highlands scrub lots for which the FWS has exerted jurisdiction pursuant to Section 9 of the ESA has evolved over time - a response to the population dynamics of Florida scrub-jays residing in an increasingly fragmented urban landscape. The information presented herein was collected from a, search of the Indian River County Environmental Planning Section file on this long-standing issue and from consultations with Jan King, of the City of Sebastian Growth Management Department and FWS staff. Most of the data was derived from historical correspondence between the FWS, City of Sebastian, and Indian River County and informational tables generated by the City of Sebastian in order to track the Sebastian Highlands scrub lots designated by the FWS as occupied or potentially occupied by scrub-jays. Existing management plans for conservation lands purchased under the Indian River County Environmental Lands Program {FloridaAffinity, Inc. and Ecotech Consultants, Inc. 1995, 1996, 1998} and a scrub-jay survey conducted for the City of Sebastian (Carroll and Associates 1997) were also reviewed. The City of Sebastian is the only government entity involved in this issue that maintains a consolidated database of the Sebastian Highlands scrub-jay habitat lots that are subject to FWS review pursuant to the provisions of the ESA. This data base is referred to by the City of Sebastian as "Areas of Scrub Habitat" and is updated periodically by the City of Sebastian upon verbal release of a designated scrub lot by the FWS (J. King, City of Sebastian, pers. comm.). The FWS began to verbally release the Sebastian Highlands scrub lots in June 1995 {J. King, City of Sebastian, pers. comm.}. In response to this FWS policy, the City of Sebastian maintains a ledger to track the regulatory status of the platted lots in Sebastian Highlands. The data base maintained by the City of Sebastian does not provide an,Y demographic. information with regard to the status of Florida scrub-jay occupation on the affected Sebastian Highlands scrub lots. The existing demographic data presently used by the FWS to determine if a designated lot is occupied by scrub- jays is based on surveys conducted by this agency in 1996 {M. Jennings, FWS, pers comm.}. Currently, the FWS reviews the regulatory status of each designated Sebastian Highlands scrub lot on a lot-by-Iot basis. At the request of the lot owner, the local FWS representative conducts a site visit to determine if proposed residential construction would result in adverse impacts to suitable scrub-jay habitat 27 I I I I I I I I I I I I I I' I II I I II which would potentially result in a taking of Florida scrub-jays (M. Jennings, FWS, pers. comm.). Although the Florida scrub-jay was federally listed as a threatened species in 1987, FWS involvement in land development actions was not common until 1991. In June 1991, the FWS informed all State, County and Local municipalities, including Indian River County and the City of Sebastian, that they were potentially liable for third party Section 9 take violations that may result from issuance of land clearing and development permits within areas occupied by Florida scrub-jays. This far- reaching FWS notification responded to the 1987 listing of the Florida scrub-jay and the 1988 Congressional amendment to the ESA which defined the responsibility of State, County and Local municipalities in ensuring that authorized activities do not violate Section 9 prohibitions against take. The potential adverse impacts of the 14,000:t lot Sebastian Highlands residential development project on the Florida scrub-jay sub population residing within the incorporated limits of the City of Sebastian was initially recognized by the FWC in the late 80's (FWS, November 12, 1996 correspondence to Indian River County - see Appendix B). By 1991, the FWC had completed a comprehensive four (4) year survey, which determined that 35 scrub-jay families occurred within the city limits of the City of Sebastian (FWS, November 12, 1996 correspondence to Indian River County) . In June 1992, the City of Sebastian agreed with the FWS to develop a habitat conservation plan. The City recognized that it was the only viable regulatory method available to resolve the conflict between residential housing construction and conservation of the Florida scrub-jay subpopulations residing within the incorporated limits of the City of Sebastian (FWS, November 12, 1996 correspondence to Indian River County). During this period the, FWC and FWS initiated informal consultation with the City of Sebastian regarding scrub-jay conservation. To guide future conservation actions, FWS staff developed a scrub- jay core habitat reserve design (Toland 1996). The objective of this reserve design was to identify those habitat areas within the City of Sebastian that were considered essential (Conservation Areas), and less essential (Incidental Take Areas), to the long-term persistence of the Sebastian scrub-jay subpopulation. The Conservation Areas selected during this early planning effort included: 1.) Sebastian PUD/lndustrial Tract (presently known as the North Sebastian Conservation Area), 2.) Sebastian Airport/Golf Course, 3.) Sebastian Elementary School-Industrial Areas, 4.) Vicker's Grove, 5.) Easy Street (presently known as Unit 17 - 34 Lots or Sebastian Highlands Scrub Conservation Area), and 6.) Pelican Elementary School and surrounding 177 platted lots in Unit 17 (Toland 1996). The Conservation Areas were selected based on the size of parcel (25 to 50 acres), contiguity and condition of xeric scrub, occupation by scrub-jays, connectivity (located within normal scrub- jay dispersal distance - two (2) miles), and ability to implement habitat management and restoration actions to increase carrying capacity of the parcel for scrub-jays 28 I I I I I I I I I I I I I I I I I I I (Toland 1996). The designated Incidental Take areas included 266 lots in the southern and northern Sebastian Highlands (Toland 1996). By 1993, a 20% reduction in the number of scrub-jay families was documented with only 27 families accounted for in the City of Sebastian (FWS, November 12, 1 996 correspondence to Indian River County). This reduction in the Sebastian scrub-jay subpopulation was attributed to a high demand for housing in the Sebastian Highlands, coupled with an absence of a comprehensive enforcement policy by the FWS and lack of willingness on the part of the City of Sebastian to develop and implement a conservation plan (FWS, November 12, 1996 correspondence to Indian River County). In 1994, the IRC Board voted to develop a county-wide HCP to address scrub-jay conservation in Indian River County, including the City of Sebastian (Toland 1996; R. DeBlois pers. comm.). In May 1994, the Sebastian City Council agreed to participate in development of the county-wide HCP provided that the process would not require expenditures from the City of Sebastian (City of Sebastian, September 7, 1994 correspondence to Indian River County). In consultation with Indian River County and the City of Sebastian, the FWS delineated the scrub habitat areas essential to survival of the Atlantic coast scrub-jay population in Indian River County (Toland 1996). These areas, as shown on Figure 3 - Scrub Jay Habitat Conservation HeareR Areas, were to serve as the foundation of the county- wide HCP for Florida scrub-jays (Toland 1996). The six (6) scrub-jay core habitat areas initially identified within the City of Sebastian, as listed above, were included in this county-wide mapping. In an effort to further several comprehensive plan policies and objectives, including front-end implementation of the county-wide HCP, Indian River County began to actively acquire large scrub parcels through its Environmental Lal")ds Acquisition Bond Program with up to 50% matching funds from the FCT Program (R. DeBlois, pers comm.). In October 1995, Indian River County acquired the 111:t acre Wabasso Scrub Conservation Area, one of the larger parcels designated by the FWS on the Scrub- Jay Habitat Conservation "Core" Areas map. In late 1996, Indian River County acquired the 387:t acre North Sebastian Conservation Area, formerly known as the AGC Industrial Tract/St. Sebastian P.U.D. Recently, Indian River County added 1 ~ acres to the North Sebastian Conservation Area, resulting in a total project area of 406:t acres. This conservation area, which is part of the proposed Sebastian HCP Scrub-Jay Habitat Compensation Areas, represents the largest scrub parcel remaining along the Atlantic Coastal Ridge in north Indian River County. During the 1994-95 time period, Indian River County endeavored to further its HCP initiatives to acquire FWS designated core scrub-jay habitat areas by creating the Sebastian Scrub Conservation Area project (FloridaAffinity, Inc. and Ecotech 29 -~'-;:T~""" -:.:-",...r~~.!F'?"'!!:f?:"iT::c"";c;;- -- I I I I I I I I I I I I I I I I I I I Consultants, Inc. 1996). This project was composed of 180 undeveloped platted lots within Unit 17 of Sebastian Highlands (FloridaAffinity, Inc. and Ecotech Consultants, Inc. 1996). The Sebastian Scrub Conservation Area project was approved in early 1995 as a FCT 50% cost-share project (Indian River County Memorandum, September 11, 1996 - see Appendix B). Both the FWS and City of Sebastian supported implementation of this acquisition project. It would have served to significantly enhance scrub-jay conservation efforts in the City of Sebastian and alleviated much of the conflict surrounding private development in the platted Sebastian Highlands lots (FWS, February 7, 1995 correspondence to Indian River County; September 11, 1996, Indian River County Memorandum - see Appendix B). In July 1996, the IRC Board voted to approve the purchase of "Phase 1" of the Sebastian Scrub Conservation Area project lots (September 11, 1996, Indian River County Memorandum). Phase 1 consisted of 50 out of 56 lots owned by Atlantic Gulf Communities (AGC) lots in Unit 17 (September 11, 1996, Indian River County Memorandum). In September 1996, the Indian River County Environmental Planning Staff recommended that the IRC Board approve the purchase of 47 individual privately-owned lots as "Phase II" of the Sebastian Scrub Conservation Area project (September 11, 1996, Indian River County Memorandum). Consolidation of this acquisition package was an immense task by the Indian River County Environmental Planning Staff, as it required Staff to contact, negotiate a purchase price, and procure signed purchase contracts with 47 different lot owners. During the negotiation process for acquisition of the subject lots, 33 of the 47 lot owners received a certified letter from the Indian River County Utilities Department (September 11, 1996, Indian River County Memorandum). This correspondence notified them that their lot was subject to a waterline assessment for construction of a new waterline serving the subject residential area (September 11, 1996, Indian River County Memorandum). The utility assessment averaged 17:f: % of the appraised value of each affected lot. The timing of this assessment impeded the County's Environmental Planning Section negotiation process to purchase the same lots for conservation. Several private lot owners expressed extreme displeasure at the prospect of paying a utilities assessment to Indian River County prior to selling the lot to the same government entity (September 11, 1996, Indian River County Memorandum) . In August 1996, the Indian River County Land Acquisition Advisory Committe,e (LAAC) voted to recommend to the IRC Board not to approve the acquisition of Phase II of the Sebastian Scrub Conservation Area project (September 11, 1996, Indian River County Memorandum). The primary concerns expressed by the LAAC was that the overall Sebastian Scrub Conservation Area project was not a viable acquisition based on expected high level of habitat management constraints and the position of the conservation project in a highly fragmented urban landscape (September 11, 1996, Indian River County Memorandum). On September 17, 1996, the IRC Board concurred with the LAAC recommendation and rejected 31 I I I I I I I I I I I I I I I I I I I purchase of the subject 47 platted lots in Phase II of the Sebastian Scrub Conservation Area project. The Board's decision halted all acquisition efforts in the Unit 1 7 platted lots comprising the Sebastian Scrub Conservation Area project (Indian River County, October 17, 1996 correspondence to the FWS - see Appendix B). The loss of the Unit 17 core scrub-jay habitat caused the Indian River County Environmental Planning Staff, in consultation with the FWS, to re-evaluate the mitigation strategy needed to develop a county-wide or Sebastian area-wide HCP. Throughout the two-year process, there had been an informal understanding between the FWS and Indian River County that acquisition and management of the North Sebastian Conservation Area, Wabasso Scrub Conservation Area, and Sebastian Highlands Unit 1 7 lots would serve to provide a substantial portion of the mitigation needed to support a county-wide HCP (FWS, November 12, 1996 correspondence to Indian River County). It is important to note that at the urging of the FWS, the IRC Board subsequently authorized the purchase of a block of 34 contiguous lots in Unit 17, a portion of the Phase 1 of Sebastian Scrub Conservation Area project. These lots are part of the proposed Scrub-Jay Habitat Compensation Areas, referred to herein as the 10:t acre Sebastian Highlands Scrub Conservation Area. The FWS supported this effort based on the opinion that the "... 34 AGC lots, in combination with Pelican Elementary School scrub, may provide enough suitable habitat to minimize the adverse effects of habitat fragmentation due to losses in the remainder of Unit 17. These scrub parcels, if properly managed, may be essential "stepping stones" for dispersal of scrub-jays from and to northern Indian River County..." (FWS, November 12, 1996 correspondence to Indian River County). In consideration of the loss of the Unit 17 scrub lots, the November 12, 1996 FWS correspondence to Indian River County identified other conservation actions that Indian River County could explore to support an HCP. Two of the referenced actions included the management of scrub habitat located on the Sebastian Airport/~olf Course and Sebastian and Pelican Island Elementary School. In October 1997, both the City the Sebastian and School Board of Indian River County agreed to review a conservation plan that requires implementation of habitat management actions on the referenced parcels (City of Sebastian, October 9, 1997 correspondence to Indian River County; School Board of Indian River County, October 2, 1997 correspondence to Indian River County - see Appendix B). In response to the FWS recommendation to continue with development an,d implementation of an HCP, the IRC Board approved a request from the Environmental Planning Section to solicit consultant proposals for development of the subject Sebastian Area- Wide Scrub-Jay Habitat Conservation Plan in December 1997. In March 1998, Indian River County issued a Request for Proposals, RFP # 8047. In July 1998 Smith Environmental Services (SES) was authorized to proceed with development of this Sebastian HCP. Consolidation of existing data and performance of field surveys to update the existing information were undertaken by SES through October 1998. An informal meeting was held with FWS staff on 32 I I I I I I I I I- I I I I I I II I I I October 29, 1998 to discuss the preliminary findings from the existing data search, field surveys, and HCP elements. Additional information needed in support of plan development was collected by SES through April 1999. In September 1999, SES submitted a final draft report to IRC for transmittal and review by all participating entities, including the public and FWS. The City of Sebastian held a public meeting to discuss the City's participation on October 27, 1999. The City Council unanimously moved to approve the HCP concept at that meeting. The City of Sebastian's City Council provided final approval to staff to proceed with submittal of HCP and ITP application at the January 12, 2000 public meeting (see Attachment A). The IRC Board held their public meeting on the Sebastian HCP on November 16, 1999. This meeting resulted in the IRC Board unanimous approval of Staff's recommendation to proceed with the Sebastian HCP and transmit such to FWS, in conjunction with the ITP application. The School Board for Indian River County held its first public meeting on the HCP on November 16, 1999. The School Board objected to a participation resolution in support of the HCP due to concerns regarding future development needs at Pelican Island Elementary School. Staff from IRC, FWS, and the School Board drafted a revised resolution for Board review and approval. This resolution, as presented in Appendix A, was unanimously accepted by the School Board at their regularly scheduled December 14, 1999 public meeting. Existing Data - Location and Number of Sebastian Highlands Scrub Lots Recorded as Occuoied or Potentially Occuoied by Florida Scrub During the initial informal consultation period between the FWS, FWC, and the City of Sebastian in 1991-92, a map was developed by the FWC, in cooperation with the FWS to define the location and number of the Sebastian Highlands lots occupied or potentially occupied by Florida scrub-jays, and thereby subject to development review by the FWS (J. King, City of Sebastian, pers. comm.). An untitled table, presented as Table 1, developed by the City of Sebastian shows that this original mapping encompassed 2030 lots. Of this total number, 553 lots had already been altered to provide residential housing. At some unknown point during this initial informal consultation period, the FWS implemented a blanket relea~e policy for all- Sebastian Highlands scrub lots that had been previously cleared and were maintained as grass or contained dense stands of pine trees (J. King, City of Sebastian, pers. comm). A total of 1,204 lots were subsequently released by the FWS under this blanket release policy. Of the 2030 scrub lots originally designated by the FWS and FWC as potentially occupied by scrub-jays, 273 scrub lots of regulatory concern remained after refinement of this original mapping. 33 I I I I I I I I I I I I I I I I I I I TABLE 1 City of Sebastian 1225 MAIN STREET 0 SEBASTIAN, FLORIDA 32958 TELEPHONE (561) 589-5537 0 FAX (561) 589-2566 :i:::":.::.:i;i::i!:.::::i::.:::.:}::::i::omGINAF1:~;!:::::HH:::::::ii:::';:.;:.tii::,,'i: \N'(j<::of:Lots.: Scrub Lots 2030 Minus lots already improved 553 Minus lots released by USFWS 1,204 Remaining Scrub Lots 273 ...... ..............ADDmONS.mO'MKP:..ON.3iL2(9S.. .............'= :!!N04:'ofL'QtS( ~~~~~~~~~~i~~~~~~~~~~!:' :;:. :. :.: : :: ..' ;':: ': : :~.: . :: "; .:L:." g. :~'~" ~~::.:::~;;;::::~~~;:~j ... ..... ... ... . . -, ..,.. ..... ..... . . .. .,.

As a result of this additional review, 119 scrub lots were added to the list, of which 26 were determined to be already developed and nine (9) were released pursuant to the FWS blanket policy. The 1995 map revision resulted in the addition of 84 scrub lots of regulatory concern. The combined 1992 and 1995 mapping data for the Sebastian Highlands scrub lots designated a total of 2,149 scrub lots of regulatory concern, of which 579 were determined to be already developed and 1,213 were subsequently released for development under the FWS blanket policy. The final result of this three (3) year informal consultation process was that residential development activities on 357 Sebastian Highlands lots were identified as subject to incidental take authorization from the FWS. Interim to this time period, on May 5, 1994, the FWS issued a letter to the City of Sebastian which defined 184 platted lots in Unit 17 of the Sebastian Highlands which needed to be acquired as part of the regional HCP that was being considered at that time. In a revised list released by the City of Sebastian on July 17, 1995, in response to a June 26, 1995 FWS directive, the number of platted lots identified in the Sebastian Highlands as occupied or potentially occupied by Florida scrub-jays had increased to 456. This table entitled City of Sebastian Scrub-Jay Areas is provided as Table 2 for review. Table 3, Sebastian Highlands Potential Scrub-Jay Habitat Lots, was generated by SES from tabulated information obtained from the updated City of Sebastian Scrub- Jay Areas - Revised 8/27/98 and, subsequently, updated pursuant to information maintained by the City of Sebastian's Growth Management Department as of October 7, 1998. Therefore, Table 3 provides the location and number of the Sebastian Highlands scrub lots considered by the FWS as occupied or potentially occupied by Florida scrub-jays as of October 7, 1 998. A total of 31 7 lots in the Sebastian Highlands are identified. Therefore, between July 1995 and October 1998, 139 lots or 30% of the Sebastian Highlands scrub lots identified in July 1995 as occupied or potentially occupied by Florida scrub-jays have been released by the FWS for residential development. Identification of Existing Data Deficiencies The existing -recorded data base reviewed by SES did not sufficiently document the extent of habitat occupancy by scrub-jays, population status, habitat quality, or acreage of restorable scrub-jay habitat within the publicly-owned lands proposed as compensation areas subject to this HCP. Surveys were conducted by SES biologists in the summer/fall of 1998 to obtain these required data. The results of these surveys are provided below in Section 3.2. 35 I I I I I I I I- I I I I I I I I I I I, TABLE 2 CITY OF SEBASTIAN SCRUB JAY AREAS THE LOTS LISTED BELOW LOCATED IN UNIT 17 OF THE SEBASTIAN HIGHLANDS HAVE BEEN IDENTIFIED BY THE UNITED STATES FISH AND WILDLIFE SERVICE AS THOSE LOTS THAT NEED TO BE ACQUIRED AS PART OF THE REGIONAL HABITAT CONSERVATION PLAN (B.C.P.). .

The primary cause for this population decline was reported to be habitat degradation from lack of fire or mechanical management actions (Toland 1996). Increased vulnerability to vehicular collisions and predators as a result of the severe habitat fragmentation are also potential factors contributing to the documented decline in the Sebastian scrub-jay subpopulation. Poor reproductive success and survival within the Atlantic Coast and Lake Wales Ridge populations in 1997 was reported to be wide-spread and was attributed to an epidemic documented across much of the Florida scrub-jay range (Breininger and Oddy 1998; Breininger 1999). In consideration of the fact that habitat quality within the affected Sebastian Highlands scrub lots continued to decline between 1 996 and 1 998 and that demographic success of Florida scrub-jay populations along the Atlantic Coast was particularly poor in 1997, SES biologists determined that that up-to-date habitat occupancy and habitat quality data, with an emphasis on habitat quality, should be obtained within the affected Sebastian Highlands scrub lots in order to accurately define the incidentai take levels and sufficiency of mitigation measures proposed under this HCP. The results of this survey, as provided below, confirmed that families within the Sebastian Highlands landscape continue to be lost. 3.2 Sebastian HCP Plan Area - Population Status and Habitat Utilization Pervasive residential development in Indian River County has resulted in an estimated scrub habitat loss of approximately 90% since pre-settlement times (Fernald 1989). Much of the remaining parcels of scrub are fragmented and in various states of degradation due primarily to widespread fire suppression. The City of Sebastian experienced rapid human population growth during the 1980's (Fernald 1989;" Fernald et al. 1992). Reflecting the increase in the human population has been a precipitous expansion of commercial retail businesses and large residential communities. From 1991 through 1998 individual family lots throughout the Sebastian Highlands residential subdivision continued to be cleared for house construction while the remaining patches of xeric oak scrub and scrubby pine flatwoods continued to grow taller and denser in the absence of wildfire or prescribed habitat management. All of these changes in the landscape have reduced the spatial extent of suitable scrub habitat in the Sebastian Highlands, precipitated a deterioration in habitat quality, exponentially increased habitat barriers and presented multiple potentially fatal scrub-jay encounters with roadway traffic, domestic pets, and toxic pollutants. As demonstrated by the documented decline in the HCP study population, each of these human-induced changes has a negative influence on the demographic success of Florida scrub-jays. Demographic studies of the Florida scrub-jay populations in Indian River County began in 1988 (Toland 1991, 1993, 1996, unpubl. data). The Indian River County scrub-jay core population was concentrated within the boundaries of the City of Sebastian and adjoining scrub properties. Two subpopulations, as described in 39 I I I I I I I I I I I I I I I I I I I Section 2.2 above, have persisted in Sebastian during this long-term study (Toland unpubl. data). These subpopulations are separated by less than 3 miles (4.8m) of predominantly built-out residential neighborhoods. As discussed above, the study population is part of the South Brevard County/North Indian River County metapopulation. This metapopulation, which extends from Winter Beach in Indian River County north to Malabar in Brevard County (Fitzpatrick et al. 1994a; Breininger and Toland unpubl. data), is composed of several sub populations that are within the normal maximum Florida scrub-jay dispersal distance (Stith et al. 1996) of one another. A scrub-jay subpopulation of at least a dozen pairs exists on the St. Sebastian River State Buffer Reserve (SBR) and extends over the Indian River-Brevard County Line to provide a linkage between the South Brevard and the Sebastian HCP study population (Breininger and Oddy 1998). Data collected during the 1993 Statewide Census (Fitzpatrick et al. 1994b), in conjunction with recent studies (Toland 1996; Breininger and Oddy 1998), provided the basis to rank this Florida scrub-jay metapopulation as the fourth largest in Florida and the most important metapopulation for species recovery along the Florida's Atlantic Coast (Breininger and Oddy 1998). A total of 240 individual scrub-jays were colorbanded to support demographic studies conducted by Toland (1991, 1993, 1996, unpubl. data) within the incorporated limits of the City of Sebastian. This colorbanding facilitated the identification of 35 territories between 1989 and 1991 (Toland unpubl. data). Data relating to nest site selection, nesting success, survival, helper influence, dispersal, mortality, food habits, and habitat suitability were collected for a sample of 174 nests. Family size averaged 3.0 individuals per group with 63% of the breeding pairs accompanied by at least one helper. Clutch size averaged 3.8 and average brood size was 3.0 (Toland un pub I. data). Median incubation date was April 7th and median hatching date was April 24th. Approximately 72% of the nestlings successfully fledged. Mean annual productivity was 1.9 young fledged per pair per year. Median fledging date was May 10th and 70% of all nesting attempts were successful in fledging at least one young (Toland unpubl. data). Habitat characteristics were assessed in one-half acre patches around each nest tree and categorized as optimal, suboptimal, ancillary, or lawn (Toland 1991). Nesting success (percentage of nest attempts that fledged at least one young) was positively correlated to nest site habitat quality; success rates for optima.l, suboptimal, ancillary, and lawn were 91, 67, 48, and 25%, respectively. Habitat features comprising each scrub-jay territory were assessed and characterized as optimal contiguous, optimal fragmented, and suboptimal fragmented. Nesting success was positively correlated with territory quality; success rates for optimal contiguous, optimal fragmented, and suboptimal fragmented were 79, 77, and 59%, respectively (Toland 1991). Mean annual productivity of scrub-jays in the study area was 2.2 young fledged per pair in contiguous, optimal scrub; 1.8 young fledged per pair in fragmented, moderately developed scrub; 1.2 young per pair 40 I I I I I I I I I- I I I I I I I I I I fledged in highly fragmented, suboptimal scrub; and about 0.5 young per pair In residential lawns. Long-term studies at Archbold Biological Station have previously documented that mean annual productivity of scrub jays is 2.0 young per pair per year in stable populations where natality counterbalances mortality (Fitzpatrick et al.1991). The subject demographic studies found that scrub-jays dispersed at earlier ages and farther distances than is reported for contiguous natural scrub landscapes (Toland unpubl. data). A total of 64 dispersals were documented, including 40 females and 24 males (Toland unpubl. data). The mean dispersal distance by females was 2.4 miles (3.8 km) [range = 0.2 mi. (0.3 km) to 5 mi. (8.0 km)] and the mean dispersal distance by males was 0.9 miles (1.4 km) [range=0.5 mi. (0.075 km) to 2.9 mi. (4.7 km)]. Four females were known to disperse 4 miles (6.5 km) between the most northern clusters of the north subpopulation and the Sebastian Highlands/Pelican Island Elementary School southernmost clusters (Toland unpubl. data). The longest dispersal was 5 miles from a female that emigrated into the Wabasso Scrub Conservation Area from a cluster located on the Sebastian Airport/Golf Course (Toland unpubl. data). Most of the documented dispersals in the City of Sebastian were 2 miles or less (80% of females and 92 % of males) (Toland unpubl. data). Breininger (1999) documented similar patterns on the urbanized and extensively fragmented South Brevard County barrier island, where females dispersed an average of 4.5 miles (7.3 km) and maleS dispersed an average of 0.6 miles (1.0 km). On the Gulf Coast, Thaxton and Hingtgen (1996) reported average dispersal distances in urban areas to be 5 miles for females and 1.2 miles (1.9 km) males. These urban dispersal patterns contrast significantly with those documented for contiguous, optimal scrub at Archbold Biological Station where mean dispersal distances for females are 0.6 miles (1.0 km) and for males are 0.2 miles (0.3 km) (Woolfenden and Fitzpatrick 1984). Scrub-jays in the Sebastian study area dispersed and nested at earlier ages than in undisturbed scrub systems. A total of 41 known-age dispersals were documented during the study (26 females and 1 5 males). The mean age of dispersing females was 14.2 months (range = 4 to 36 months). The mean age of dispersing males was 28.2 months (range = 11 to 60 months) (Toland unpubl. data). Breeding by yearlings, especially females, was relatively common during the Sebastian scrub-jay study (Toland unpubl. data). Florida scrub-jays will breed earlier than normal when the chance arises in disturbed landscapes subject to population declines (Breininger 1999). Nesting by yearlings has also been reported for scrub-jay subpopulations in Palm Bay and the South Brevard County barrier island (Breininger 1999). During 1993, Indian River County and the City of Sebastian were censused for Florida scrub-jays as part of the Florida state-wide survey (Fitzpatrick et al. 1994b). This survey resulted in documentation of 52 families of scrub-jays in Indian River 41 1- I I I I I I I I' I I I I, I I I I I I I County: none on the barrier island, 12 on the Ten Mile Ridge, and 40 on the Atlantic Coastal Ridge (Toland 1993, 1996). The majority of remaining scrub-jay families in Indian River County continued to persist in the incorporated limits of the City of Sebastian, where scrub-jay territories declined from 35 in 1991 to 27 in 1993 (Toland unpubl. data, Toland 1996). Most of the territories that were abandoned were in outlying parcels of the Sebastian Highlands that were composed of predominantly disturbed, overgrown mesic flatwood and palmetto-Iyonia shrubland vegetation, including slash pine (Pinus elliottil1, cabbage palm (Sabal palmetto), wax myrtle (Myrica cerifera), gallberry (/lex glabra), saw palmetto (Serenoa repens), fetterbush (Lyonia fruticosa), and staggerbush (L. lucida),'as well as landscaped lawns, ornamental plants, and scattered live oaks (Quercus virginiana). This disturbed matrix habitat characterizes the majority of the habitat fragments remaining within the platted residential lots of Sebastian Highlands. The 1996 Florida scrub-jay population census for Sebastian documented a continued decline down to 20 breeding pairs (Toland 1996, unpubl. data). During late summer/early fall of 1998, known remaining territories were censused for 51 hours between July 19th and October 14th in support of this HCP. Following survey methods used since 1988 (Fitzpatrick et al. 1991), this study documented the loss of 4 more territories within the Sebastian Highlands subdivision, resulting in a total of 16 territories within the incorporated limits of the City of Sebastian. This represents a 54% population decline from the 35 breeding pairs documented in the City of Sebastian in 1991 (Toland unpubl. data). The location of these remaining territories is provided in Section 2.1 above. One notable increase occurred in the Sebastian Highlands-Unit 17/Pelican Island Elementary School south subpopulation cluster, where the scrub-jay territories increased from 3 to 5. This increase in territories was a result of territory budding by 2 colorbanded males. The Sebastian south subpopulation also includes the Wabasso Scrub Conservation Area cluster containing two (2), possibly three (3), breeding pairs. The Wabasso Scrub Conservation Area is located just south of the incorporated limits of the City of Sebastian (see Figure 2). The Wabasso Scrub Conservation Area is less than one mile south of the Pelican Island Elementary School/Sebastian Highlands Conservation Area scrub-jay subpopulation (see Figure 2 - "Unit 17 Conservation Areas"). The Wabasso Scrub Conservation Area scrub-jay families were colorbanded in support of demographic studies during 1988 through 1991 (Toland 1996, unpubl. data). Several dispersals between this cluster and the Pelican Island Elementary School cluster occurred between 1990 and 1993 (Toland unpubl. data) Two colorbanded scrub-jay families were monitored at the Wabasso Scrub Conservation Area through the 1996-97 breeding season. These families primarily occupy the north one-half of the conservation tract. The 1998 survey conducted at the Wabasso Scrub Conservation Area in support of this HCP found that these two (2) families continued to occupy nearly the same habitat areas. However, a 42 I I I I I I I I- I I I I I- I I I I Ii I third pair of unbanded scrub-jays was observed foraging in the northernmost section of the habitat restoration parcel that was mechanically renovated in January 1998. This area is adjacent to,. and south of, the two historic territories (Toland unpubl. data). Therefore, the 1998 nesting season included a total of two (2) distinct Florida scrub-jay territories and a third pair possibly pioneering a territory in the restored area. Each of the two (2) colorbanded scrub-jay families at Wabasso Scrub Conservation Area included two (2) juveniles as recent as August 6, 1998. Therefore, their mean annual productivity was 2.0 nutritionally-independent young per pair per year. Nesting was not recorded for the third and newest pair of scrub-jays that were observed foraging in the northern section of the habitat restoration parcel, as well as on the adjacent golf course. Although the number of territories (2) remained stable on the Wabasso Scrub Conservation Area from 1988 through 1998, individuals per family had been declining prior to habitat restoration in 1998 (Toland unpubl. data). Implementation of the Wabasso Scrub Conservation Area Habitat Restoration and Management Plan (SES 1996) during early 1 998 initially appears to have been successful in restoring habitat conditions that are suitable for recruitment of an additional scrub-jay on this conservation tract. Additional habitat restoration and management activities, as covered under this HCPj are needed on Wabasso Scrub Conservation Area to optimize the scrub habitat for use by scrub-jays. 3.3 South Brevard County Florida Scrub-Jay Population Status From 1993 through 1998, colorbanding and monitoring of Florida scrub-jays was accomplished just north of the City of Sebastian in southern Brevard County (Fitzpatrick et at. 1994b; Breininger and Oddy 1998). From 1997 through 1998, investigations included colorbanding of 107 individuals in 42 breeding territories (Breininger and Oddy 1998). The study sites extended over 8 miles from the Sebastian Buffer Reserve along the southern Brevard County line to the City of Malabar (Breininger and Oddy 1998). Data were also collected on 26 territories in suburban Palm Bay and 12 territories on the Sebastian Buffer Reserve. Between 1993 and 1998, all subpopulations in southern Brevard County declined by more than 50% inclusively, due primarily to expansive decline in habit~t suitability for scrub-jays (Breininger and Oddy 1998). A widespread epidemic during 1 998 may have augmented scrub-jay mortality in much of Florida including this metapopulation (Breininger and Oddy 1998). Breininger and Oddy (1998) found that almost no habitat in southern Brevard County was optimal for scrub-jays and most was suboptimal due to long-term fire suppression and resulting habitat succession and overgrowth. 43 I I I I I I I I II I I I~ I I I I I I I The immediate mechanical cutting of trees and aggressive application of prescribed fire was determined to be an essential action at all of the south Brevard County sites to prevent extinction of this population (Breininger and Oddy 1998). This urgency to implement immediate habitat restoration activities to slow the rates of scrub-jay population decline extends over into the HCP Plan Area and is reflected in the HCP operating conservation program presented below in Section 5.0. 3.4 Documentation of the Occurrence of Federal and State Protected Species Within the HCP Plan Area The HCP Plan Area was assessed for the occurrence of other Federal or State protected species by referencing the Florida Natural Areas Inventory (FNAI) December 1997 database entitled Species and Natural Community Summary for Indian River County, by reviewing past studies conducted on the Scrub-Jay Habitat Compensation Areas by FloridaAffinity, Inc. and Ecotech Consultants, Inc. (1995, 1996, 1998), and by reviewing studies completed by the FWS. In addition, random pedestrian transect surveys to determine the presence of protected species were performed as part of the 1998 field surveys conducted in support of this HCP. Protected species are plants and animals which are listed as endangered, threatened, or species of special concern by the FWS in 50 CFR 17.11 & 17.12, by the FWC in Rules 30-27.003&004 and 39-27.05, F.A.C., and Florida Department of Agriculture and Consumer Services (FDACS) in Section 581.185-187, F.S. The FWC document, Official Lists of Endangered and Potentially Endangered Fauna and Flora in Florida, published August 1, 1997 and compiled by Tom H. Logan, FWC Endangered Species Coordinator, provides a summary listing of all of the protected species of concern occurring within the State of Florida. The Federal interpretation of take is described above in Section 1.2. Table 4 provides a list of protected species either confirmed to occur or expected to occur in the potential Florida scrub-jay habitat identified within the HCP Plan Area (Toland unpubl. data). As stated in Section 2.4 above, federally listed plant species do not occur within the HCP Plan Area. A Preliminary Vascular Plant List prepared by The Institute for Regional Conservation from site surveys conducted on November 21, 1995 at the Wabasso Scrub Conservation Area, Sebastian Highlands Scrub Conservation Area, and North Sebastian Conservation Area is provided in Appendix C.. This plant list confirms that no federally listed plants occur on the subject conservation properties. Several wetland dependent avian species and the bald eagle (Haliaeetus leucocephalus) were observed to use wetland habitats located within the landscape matrix of the HCP Plan Area (Toland unpubl. data). 44 I I I I I I I I I I I I I I I I I I I Table 4. Protected Wildlife Species Occurring or Potentially Occurring within the HCP Plan Area. Common Name Scientific Name Regulatory Agency Protection Status Eastern Indigo Drymarchon corais FWS and FWC Threatened and Snake couperi Threatened Florida Scrub-Jay Aphelocoma FWS and FWC Threatened and coerulescens Threatened Florida pine Pituophis FWC Species of Special snake melanoleucus Concern (SSC) mU.Qitus Florida mouse Podomys f10ridanus FWC SSC Florida gopher Rana capito FWC SSC frog Gopher tortoise Gopherus FWC SSC Polyphemus 3.5 Other Regulatory Laws Relevant to the HCP Plan Area Residential development actions conducted within the ITP impact area have the potential to result in the "taking" of State protected wildlife species listed above in Table 4 and/or the dredging and filling of wetlands. In accordance with Chapter 39, F.A.C., it is the sole responsibility of the private landowners of the affected Sebastian Highlands lots to procure permit authorization from the FWC prior to engaging in construction activities that may result in the taking of a State protected species, such as the gopher tortoise and/or listed burrow commensals. Habitat restoration and management actions to be implemented on the Scrub-Jay Habitat Compensation Areas in accordance with this HCP will serve to provide habitat benefits to the protected species potentially occurring within these habitat areas. Wetlands and surface waters are protected by the State of Florida in accordance with the regulatory program authorized under Part IV, Chapter 373, F.S. The Florida Department of Environmental Protection (FDEP) administers this program for single- family residential projects. Wetlands are afforded Federal regulatory protection pursuant to Section 404 of the Clean Water Act (33 U.S.C. 1344). The U.S. Army Corps of Engineers (ACOE) administers this Federal program. Again, it is the sole 45 I I I I I II I' I I I I I I I I I I I I responsibility of the private landowners of the affected Sebastian Highlands lots to procure permit authorization from the appropriate regulating authorities. Habitat restoration and management actions to be implemented on the Scrub-Jay Habitat Compensation Areas in accordance with this HCP, such as construction of fire perimeter breaks, shall avoid, wherever practicable, dredge and fill impacts to wetlands and/or surface waters. Federal authority for protection of historic properties is set forth in the National Historic PreseNation Act of 1996 (Public Law 89-655), as amended. The State of Florida regulates impacts to significant archeological or historical sites under the provisions of section 267.061, F.S. It is unlikely that significant archeological or historic properties remain within the Sebastian Highlands ITP impact area due to the present level of development within this area. A county-wide cultural resource survey was completed in 1 992 by The Archeological Historical ConseNancy, Inc. (FloridaAffinity, Inc. and Ecotech Consultants, Inc. 1995). This survey determined that no archeological or historic sites are known or expected to occur on the Indian River County-owned Scrub-Jay Habitat Compensation Areas (FloridaAffinity, Inc. and Ecotech Consultants, Inc. 1995, 1996, 1 998). It is doubtful that the remaining Scrub-Jay Habitat Compensation Area properties contain historical sites. As part of FCT Grant Award Agreement, Indian River County is obligated to take appropriate protective measures i~ the event historic sites are found on their conservation properties (FloridaAffinity, Inc. and Ecotech Consultants, Inc. 1 995). The habitat restoration and management actions to be implemented on the Scrub-Jay Habitat Compensation Areas in accordance with this HCP are directed to minimize adverse impacts to the conseNation site by implementing measures which minimize soil disturbance. The City of Sebastian shall inform citizens of the above State and Federal regulations as part of the City's building permit application package for residential construction. Local zoning regulations and hazardous material concerns potentially affecting the Scrub-Jay Habitat Compensation Areas have been assessed by the Applicants as part of the land acquisition procedures for these properties (R. DeBlois pers. comm.). 3.6 Sebastian HCP Plan Area Habitat Types and Surrounding Land Use Descriptions Scrub vegetation community types are associated with ridges of well-drained to moderately-well drained soils (Kurz 1942; Laessle 1942, 1958; Schmalzer et al. 1999). Along the Atlantic Coastal Ridge, scrub communities occur as patches within a matrix of poor to moderately-well drained flatwoods and isolated wetlands (Breininger et al. 1988, 1991; Schmalzer et al. 1999). This diverse mosaic of habitat types describes scrub landscapes that are optimal for Florida scrub-jays (Fitzpatrick et al. 1991; Breininger 1992; Breininger et al. 1995, 1996b). 46 1 1 1 I, 1 1 1 1 1 I I I I I I I I I I The classification of the habitat types identified within the scrub landscapes in the HCP Plan Area are generally based on the FNAI Guide to the Natural Communities ot Florida (FNAI 1990) classification system. A brief description of each community type, including associated soils, is presented below. The landscape context of the HCP Plan Area is clearly displayed on Figure 2. It is primarily comprised of suburban/urban complex. A detailed description of habitat types within the Indian River County-owned Scrub-Jay Habitat Compensation Areas can be found in the management plans developed for each of these sites in support of the FCT grant awards (FloridaAffinity, Inc. and Ecotech Consultants, Inc. 1995, 1996, 1998). The Sebastian Highlands ITP impact area is characterized by small remnant patches of scrub and mesic habitat communities sparsely interspersed within a massive, fast growing urban residential landscape. Figure 2 vividly portrays the multiple habitat disturbances that have occurred within the historical Atlantic Coastal Ridge scrub landscape as a result of development of the Sebastian Highlands subdivision. With the exception of the affected Unit 17 scrub lots located near the Pelican Island Elementary School compensation area, most of the potential scrub-jay habitat areas remaining within the Sebastian Highlands are composed of disturbed and overgrown mesic flatwood and palmetto-Iyonia shrubland vegetation, as described above in Section 3.2. Review of the Soils Survey of Indian River County, Florida (Wettstein et al. 1987) determined that the mesic communities within the ITP impact area occur primarily on the nearly level, poorly drained EauGallie, Myakka, Immokalee, Oldsmar, and Malabar fine sands. Fragmented patches of xeric oak scrub remain within the delineated affected Unit 17 residential lots and both of the Unit 17 Scrub-Jay Habitat Compensation Areas (Pelican Island Elementary School/Sebastian Highlands Scrub Conservation Area) (see Figure 2). The vegetative composition of this scrub community is generally characterized by an open canopy of slash pine with an open to closed shrub understory dominated by scrub oaks (Quercus geminata, a. chapmanii, Q. myrtitolia), staggerbush, tarflower (8etaria racemosa), saw palmetto, shiny blueberry (Vaccinium myrsinites), and hogplum (Ximenia americana). A diversity of herbaceous ground cover species is found within this habitat type, including: beak rush (Rhynchospora megalocarpa), silk grass (Pityopsis graminitolia), gopher apple (Licania michauxit), prickly pear cactus (Opuntia humitusa), blazing star (Liatris spp.), deer tongue (Carphephorus spp.), and wiregrass (Aristida stricta). Ground lichens (Cladonia spp.) and Florida rosemary (Ceratiola ericoides) are also associated with this scrub habitat. The scrub communities identified in the subject Unit 17 areas are associateOd with the nearly level to gently sloping, moderately-well drained Archbold and Pomello sands, 0 to 5% slopes (Wettstein et al. 1987). The vegetative structure of the oak scrub habitat occurring within Unit 17 varies - a response to time since fire and surrounding human-induced disturbances. Some of the oak scrub habitat within the Unit 17 Scrub-Jay Habitat Compensation Areas is currently unsuitable for use by scrub-jays due to a dense pine canopy, overgrown 47 I I I I I I I I I I I I I I I I I I I shrub stratum, and absence of open patches of sand. These areas can be restored to optimal scrub-jay habitat conditions by application of appropriate habitat restoration strategies. A small patch of the oak scrub habitat remaining in Unit 17 on and adjoining the Pelican Island Elementary School compensation area exhibits optimal scrub-jay habitat conditions, e.g. sparse pine canopy cover and a low, open shrub community. The scrub habitat types occurring within the Unit 17 ITP impact area and Scrub-Jay Habitat Compensation Areas have not been managed in the past. As part of an environmental education program at Pelican Island Elementary School, the School Board authorized the DOF to conduct a prescribed burn of the oak scrub habitat within the Pelican Island Elementary School compensation area (R. DeBlois pers. comm.). This prescribed burn was successfully implemented in the Spring 1999 (R. DeBlois pers. comm.). Habitat types defined on the Sebastian HCP Scrub-Jay Habitat Compensation Areas include: sand pine, oak scrub, rosemary scrub, scrubby flatwoods, mesic flatwoods, palmetto-Iyonia shrubland, disturbed lands, depression marsh, and inland swamp. The scrub habitat types are: sand pine scrub, oak scrub, rosemary scrub, and scrubby flatwoods. Each of these habitat types have formed in association with somewhat poorly drained to excessively drained soil types, and exhibit a scrub oak vegetative cover component ranging from 5% to > 50%. The mesic matrix habitat types are: mesic flatwoods and palmetto shrubland. These natural communities are associated with poorly drained soils and exhibit a less than 5 % scrub oak cover. The disturbed habitat types are those areas altered by anthropogenic activities and are presently infested by Brazilian pepper (Schinus terebinthifolius) and/or covered by wild grape vine (Vilis spp.). The disturbed habitat areas were found to occur on both xeric and mesic soil types. The marshes and inland swamp are depressional wetland communities dominated by herbaceous vegetation and associated with very poorly drained sandy soils. Review of historical imagery revealed that the inland swamp habitat type identified on the North Sebastian Conservation Area was previously an open marsh habitat which has succeeded into a wetland forest dominated by a mixture of hydrophytic trees as a result of fire exclusion. Sand Pine Scrub The sand pine scrub habitat type is found on the North Sebastian Conservation Area along the higher areas of the Atlantic Coastal Ridge. This community type occurs on the nearly level to gently sloping moderately-well drained Archbold and Pomello sand, o to 5% slopes and the excessively-drained St. Lucie sand, 0 to 8% slopes and Astatula sand, 0 to 5% slopes (Wettstein et al. 1987). It is vegetatively characterized by a dense sand pine (Pinus clausa) canopy with an oak scrub 48 I I I I I I I I I I I I I I I I I I I understary. This understary is similar in vegetative campasitian to. the aak scrub faund in Unit 17 af Sebastian Highlands, as described abave. Review af histarical imagery faund that the extent af the sand pine scrub farest habitat an the Narth Sebastian Canservatian Area has expanded significantly aver time due to. reduced fire frequencies. Oak Scrub The aak scrub habitat type is faund an each af the Scrub-Jay Habitat Campensatian Areas, with the largest cantiguaus patch accurring an the Wabassa Scrub Canservatian Area. The aak scrub habitat accurs primarily an the nearly level to. gently slaping, maderately-well drained Archbald and Pamella sands, 0 to. 5% slapes (Wettstein et a/. 1987). Within the Narth Sebastian Canservatian Area, aak scrub is also. assaciated with the nearly level and samewhat poorly drained Satellite fine sand sail type (Wettstein et a/. 1987). The apen aak scrub areas determined to. histarically accur an the excessively-drained sails are currently daminated by sand pine, as described abave. The vegetative descriptian for this habitat type is provided abave for the aak scrub identified in Unit 1 7 af Sebastian Highlands. Rosemarv Scrub A small patch af rosemary scrub was identified an the Narth Sebastian Conservation Area. This scrub habitat type was differentiated from the surrounding sand pine and oak scrub habitat types due to a daminance of Flarida rasemary with numeraus apen, sandy areas. This scrub habitat type occurs an the nearly level, somewhat poorly drained Satellite fine sand soils (Wettstein et a/. 1987). Scrubbv Flatwoads The scrubby pine flatwaads scrub habitat type was identified within the Narth Sebastian Conservation Area and along the western boundary af the Sebastian Airpart campensatian properties. It is vegetatively characterized by a shrub layer dominated by saw palmetto. interspersed by scrub aaks and an open to. closed canapy of slash pine. Sails af the scrubby flatwaads identified on the subject campensatian areas are the nearly level, paorly drained Myakka and Immakalee sands and the nearly level, somewhat paarly drained Satellite sands (Wettstein et a/. 1987). Mesic Flatwoads Mesic flatwoads are the predominant matrix habitat type of the scrub landscapes within the Scrub-Jay Habitat Campensatian Areas. This natural cammunity type is comman on the North Sebastian Canservation Area/Sebastian Airport compensation sites and Wabasso Scrub Conservatian Area. It is vegetatively characterized by a dense slash pine canopy with a shrubby understary dominated by saw palmetto., fetterbush, and gallberry. Herbaceaus ground caver, daminated by wiregrass, is 49 I I I I I I I I I I I I I I I I I I I, J sparse due to either a thick layer of pine needle duff or the dense shrub layer. Cabbage palm is scattered within the mesic slash pine canopy at the North Sebastian Conservation Area. Soil types of the mesic flatwoods on the Scrub-Jay Habitat Compensation Areas are the nearly level, poorly drained Myakka, EauGallie, and Immokalee fine sands (Wettstein et al. 1987). Palmetto - Lvonia Shrubland The palmetto-Iyonia shrubland classification is applied to describe a natural community that is essentially a mesic flatwoods without the pine canopy component. This habitat type is identified within the North Sebastian Conservation Area and Wabasso Scrub Conservation Area. The dense shrub community characterizing this habitat is dominated by saw palmetto, fetterbush, and gallberry on the same Myakka and Immokalee fine sand soils (Wettstein et al. 1987) as the mesic pine flatwoods Disturbed Lands This land use classification type is used to describe vegetatively disturbed areas on poorly drained soils dominated by Brazilian pepper (Schinus terebinthifolius), an exotic and invasive species and/or grape vine, a native species that rapidly colonizes disturbed sites. Deoression Marsh/lnland Swamo Numerous, isolated depression marshes are interspersed within the scrub landscapes at the North Sebastian Conservation Area/Sebastian Airport and the Wabasso Scrub Conservation Area. They are formed on the very poorly drained Myakka fine sand, depressional soil (Wettstein et aJ. 1987). The marshes are generally characterized by a dense herbaceous cover dominated by sand cordgrass (Spartina bakenl, broomsedges (Andropogon spp.), blue maidencane (Amphicarpum muhlenbergianum), red root (Lachnanthes caroliniana), hatpin (Eriocaulon spp.), yellow-eyed grasses (Xyris spp.), and rushes (Rynchospora spp). Shrub species including buttonbush (Cephalanthis occidentalis) and willow (Salix caroliniana) occur in the deeper pockets of these wetland communities. Wax myrtle (Myrica cerifera) and saltbush (Baccharis halmifolia) are invading the upper margins of some of the depression marshes. The inland swamp is a successional forested wetland community dominated by re.d maple (Acer rubrum). The primary disturbance regime within the Scrub-Jay Habitat Compensation Areas that negatively influences the persistence of Florida scrub-jays on these properties is fire suppression and habitat fragmentation. Implementation of the scrub management and restoration strategies recommended herein is critical to the viability of the Sebastian Florida scrub-jay population and the Atlantic Coastal Ridge scrub ecosystem on which it depends. 50 1 1 I I, I 1 I 1 I I I I I I I I 1 I I 4.0 IMPACT ASSESSMENT 4.1 Determination of Acreage of Potential Scrub-Jay Habitat to be Impacted, Preserved and Restored 4.1 .1 Methodoloav Habitat Studies High resolution digital orthophoto quads (DOOs) were obtained for the HCP Plan Area to display required data. The DOOs are available across a wide area and provide consistent, convenient, high quality templates for managing and displaying spatial data using readily available software (e.g. ArcView, ARC/INFO) on most hardware platforms, using Windows 95 or Unix operating systems (Breininger and Oddy 1998). The DOOs were used in this analysis as a template to view the spatial location of the ITP impact area, Scrub-Jay Habitat Compensation Areas, and core areas of the South Brevard County/North Indian River County metapopulation, and to assign specific habitat and demographic attributes with digital photography as a background. Imagery from 1943, 1957, and 1965 were obtained to qualitatively describe habitat changes over time for purposes of assessing the potential for habitat restoration to provide optimal scrub-jay habitat conditions. As illustrated by Figure 2, use of DOQs is valuable in this study as they clearly reveal the predominant land use within the HCP Plan Area. Habitat pOlygons were digitized for each of the Scrub-Jay Habitat Compensation Areas in ARC/INFO coverage and include the following attributes: acreage of habitat polygons, habitat type, potential for restoration as scrub-jay habitat, soil moisture condition (xeric, mesic, or wet), need for pine thinning, shrub' height class (a measurement of habitat quality), and occupation by scrub-jays. Definition of these attributes for each polygon provided a mechanism to evaluate the regulatory compliance of this HCP and to determine the habitat restoration/management needs for each site. Field surveys were conducted in the summer/fall of 1998 to review the mapped polygons for accuracy with regard to habitat composition and structure and potential for habitat restoration to provide optimal scrub-jay habitat conditions. Additional surveys were conducted at each compensation area to up-date the number and extent of. scrub-jay territories occupying these sites. . The mapped habitat polygons are presented for each Scrub-Jay Habitat Compensation Areas in the Figures 4, 6, and 8 with the digital photography as a background. Figures 5, 7, and 9 provide the corresponding habitat polygons sequentially numbered for identification and evaluation.

The total calculated acreage for the mapped habitat polygons described in Table 5 and covering all publicly owned land assessed under this HCP is 645.8 acres. The total surveyed acreage for the same area is reported to be 665.5:t acres. Therefore, a 3% error in this analysis is recognized, however it is considered insignificant as it represents an "under-compensation" of calculated mitigation acres. Please note that the four (4) acre parcel located along the southern boundary of the Pelican Island Elementary School complex and the subject of future take authorization under this HCP is not shown on any of the figures presented herein. The boundaries of this area are defined as the undeveloped lands located on the south boundary of the Pelican Island Elementary School grounds, exclusive of the 1 2:t acre compensation area described by Polygon Nos. 44, 45, 46, and 47 (Figure 7). Potential scrub-jay habitat comprising the majority of the total 330.5:t acre Scrub- Jay Habitat Compensation Areas are defined by the scrub habitat types: sand pine scrub, oak scrub, rosemary scrub, and scrubby flatwoods. It includes the sand pine scrub and scrubby flatwoods which have become forest (> 65% tree canopy cover) due to the absence of period fire and habitat fragmentation. Review of the historical imagery determined that these currently forested scrub habitat areas exhibited suitable open scrub-jay habitat attributes in the past. Potential scrub-jay habitat also includes mesic flatwoods within 328' (100m) of, and palmetto-Iyonia shrublands adjacent to, the delineated scrub habitat types. The restoration and management of these mesic habitat areas as potential scrub-jay habitat must be considered under this HCP. Numerous studies have documented that scrub-jay territories are not restricted to oak scrub ridges (Breininger et at. 1 991, 1995, 1998a; Duncun et at. 1995; Breininger and Oddy 1998). Figures 5, 7, and 9, have been color-enhanced to facilitate rapid interpretation c;>f. the assigned attributes. As presented in Section 2.4.1 above, optimal Florida scrub-jay habitat (Fitzpatrick et at. 1991; Breininger 1992; Breininger et at. 1995, 1996b) occurs as patches of oak scrub (focal habitat), embedded within a low and open mesic shrub landscape (matrix habitats) (Breininger et at. 1 996b). Native matrix habitats, principally mesic pine flatwoods and depression marshes, are important components of the scrub landscape used by Florida scrub-jay (Breininger et at. 1995, 1996b). Matrix habitat areas without scrub oak and within approximately 1970' (600m) of scrub oak were documented by Breininger and Oddy (1998) to be frequently used by scrub-jays. These native matrix habitats provide prey species for Florida scrub-jays and habitat for other species of conservation concern (Breininger et at. 1995, 1996b; Schmalzer et at. 1999). The high flammability of the native matrix habitats often serves to spread fire into the fire-resistant oak scrub habitats (Breininger et at. 1995, 1996b). The matrix habitats provide habitat to Florida scrub-jays during periods of habitat degradation of the preferred oak scrub habitat (Breininger and Oddy 1 998). 58 I I Table 5.

Tall vegetation reduces the scrub-jays ability to scan their surroundings for long-distances; thereby increasing their vulnerability to predation by woodland hawks (Woolfenden and Fitzpatrick 1984; Schmalzer et al. 1994; Breininger et al. 1995; Breininger and Oddy 1998). Management of the matrix habitat types as low, open habitat areas enhances the dispersal potential of scrub- jays (Breininger and Oddy 1 998). The spatial arrangement of habitat structure affects demographic success and must be considered in management for population persistence of Florida scrub-jays (Breininger et al. 1991, 1995, 1998a; Duncun et al. 1995; Breininger and Oddy 1998). Mesic flatwood forests that were observed to be present on historical imagery within the Scrub-Jay Habitat Compensation Areas and are located > 328' (100m) from focal scrub habitat types were not classified as potential scrub-jay habitat to be covered under this HCP. Each habitat polygon was also evaluated to define management needs for restoration to conditions that are optimal for scrub-jays. This includes habitat quality considerations of pine thinning and shrub height class. It also defines the current extent of habitat use by existing scrub-jay territories to avoid negative impacts to these territories as a result of proposed habitat restoration and management actions. The acreage of habitat currently used by scrub-jays on the Scrub-Jay Habitat Compensation Areas was determined to assist in the determination of the regulatory sufficiency of this HCP. Optimal scrub-jay habitat features a tree canopy cover of less than 15%. Therefore, potential scrub-jay habitat polygons exhibiting a tree canopy cover of greater than 15% are recommended for pine thinning. Review of Table 5 shows that pine thinning is recommended within most of the habitat polygons. The shrub height mapping classes evaluated for each habitat polygon included: 1.) too short [entire polygon < 3.9' (1.2m) tall], 2.) optimal [polygon exhibited a mosaic of too short (<3.9' (1.2m)) and optimal (3.9-5.6' (1.2-1.7m tall))] and had no too tall scrub [> 5.6 (1. 7m) tall] patch greater than 1 acre in size, 3.) mixed tall (polygon exhibited a mix of too tall patches > 1 acre in size and short and/or optimal scrub), and 4.) too tall [entire polygon was > 5.6' (1.7m tall)]. This attribute was used to classify habitat quality within the shrub stratum for purposes of recommending mechanical and fire management needs. Table 6, Habitat Quality Classificatio!1 Regarding Shrub Height and Habitat Management Needs, describes each habitat quality attribute. Scrub-Jay Occuoancy Studies The final characteristic that was evaluated was the determination of present use of the habitat polygon by Florida scrub-jays. As presented above in Section 3.2, the known remaining scrub-jay territories located within the compensation areas and 61 I I I I I I I I I' Ii I I I I I I I I I Table 6.

(1991 ). Where contiguous territories did not facilitate initiation of disputes between families to define territory boundaries, occupancy of a habitat polygon area was based on observed presence or absence of scrub-jays, in conjunction with an assessment of the presence of habitat features suitable for use by scrub-jays. The surveys were primarily completed within the Scrub-Jay Habitat Compensation Areas to ensure that management strategies recommended within this HCP would not adversely impact existing territories and to provide accurate base data to estimate the potential number of scrub-jay territories that the compensation areas can support when restored to optimal scrub-jay habitat conditions. 4.1.2 Acreage of Privatelv-Owned Sebastian Highlands Potential Scrub-Jay Habitat Lots Pursuant to an informal agreement between the FWS and the Applicants, the assessment of the level of anticipated incidental take for this HCP is primarily habitat-based. It considers the habitat contained within the privately-owned Sebastian Highlands scrub lots presently designated by the FWS as occupied or potentially-occupied by scrub-jays. For purposes of this HCP, the average area of each affected Sebastian Highlands residential lot is estimated to be one-quarter acre. Therefore, the level of anticipated incidental take proposed under this HCP, expressed in terms of habitat-areas, is calculated based on the total number of affected lots multiplied by an average lot size of one-quarter acre. Based on the existing lot data compiled by SES and presented in Table 3, 317 Sebastian Highlands scrub lots, comprising 79.3:1: acres, are presently recorded by the City of Sebastian as containing potential scrub-jay habitat. Figure 2 shows the spatial location of these specified lots (impact areas). These lots are located within the overalllTP impact area covered under this HCP. 4.1.3 Acreaae of Existing (Occuoiedl Scrub-Jay Habitat on the Scrub-Jay Habitat Comoensation Areas Field surveys conducted in support of this HCP found that almost no habitat was optimal for scrub-jays on the North Sebastian Conservation Area, Sebastian Highlands Scrub Conservation Area (34 lots in Unit 17), and Pelican Island Elementary SCho<?1 Scrub-Jay Habitat Compensation Areas. The majority of the scrub-jay habitat areas that occur on the Scrub-Jay Habitat Compensation Areas have more than one habitat feature that is suboptimal for use by scrub-jays. Scrub-jay habitat quality at Wabasso Scrub Conservation Area is higher than the other compensation areas covered under this HCP. This is a result of a wildfire that burned the northern oak scrub habitat areas approximately 10 years ago and the implementation of a timber operation in 1998 within a 34.6:1: acre sand pine forest located in the southeastern area of the site. This forest habitat type was not used by scrub-jays prior to timbering. The 63 II I I I I I I I I I Ii Ii _ J I I I I I I I timber operation was completed as part of a mitigation plan. to compensate for the take of one (1) Florida scrub-jay territory incidental to the County Road 512 improvements project (FWS Log No. 4-1-96-432). As clearly stated on Table 5 and Figure 9, this 34.6:t acre parcel (Polygon 55) is not included as mitigation under this Sebastian HCP. This is due to the fact that Indian River County already used this area as compensatory mitigation for the take of Florida scrub-jays incidental to implementation of the County Road 51 2 improvements project. Only 38:t acres of potential scrub-jay habitat located on the Wabasso Scrub Conservation Area is being proposed as part of the Scrub-Jay Habitat Compensation Areas proposed under this HCP (see Table 5). This compensation area is identified as Polygon Nos. 48, 50, and 51 on Table 5 and Figure 9. Figure 9 shows Polygon 55 as occupied by Florida scrub-jays for informational purposes only and is not intended to indicate inclusion as a compensatory mitigation area. The assessment of the extent of existing (occupied) scrub-jay habitat on the compensation area was based on the presence of suitable scrub-jay habitat features (Breininger et al 1995, 1996; Breininger and Oddy 1998), in conjunction with the documented presence of scrub-jay territories, pursuant to the 1 998 scrub-jay census conducted in support of this HCP. Using the habitat-based assessment procedure, which is consistent with the methodology applied to quantify the amount of incidental take proposed under this HCP, 194.1::!: acres of suitable, occupied scrub-jay habitat were determined to occur within the Scrub-Jay Habitat Compensation Areas (see Table 5). 4.1.4 Acreage of Unoccuoied. Restorable Scrub-Jay Habitat on the Scrub-Jay Habitat Comoensation Areas The acreage of unoccupied, restorable scrub-jay habitat occurring within the Scrub- Jay Habitat Compensation Areas is based on a review of historical imagery dating back to 1943, presence of restorable scrub-jay habitat features, and consideration of the influence of matrix habitats to the demographic success in scrub-jays. As presented in Table 5, 129.9:t acres of unoccupied, restorable scrub-jay habitat was determined to occur within the Scrub-Jay Habitat Compensation Areas. 4.2 Estimated Amount or Extent of Take Based on existing data collected from the City of Sebastian and a survey conducted in the ITP impact area in the summer/fall 1998, issuance of the Sebastian HCP ITP is anticipated to result in the taking of 79.3::!: acres (317 lots) of habitat currently identified by the FWS as occupied and potentially occupied by scrub-jays. As a result of implementation of scrub-jay habitat enhancement measures directed by this HCP, take is also expected at some time in the future on 88.1 acres of commercial property on Sebastian Airport and four (4) acres on the southern 64 I I I I I I, I I Ii I I I I I I I I I I boundary of the Pelican Island Elementary School. As noted above, these habitat areas are presently unoccupied and unsuitable for use by scrub-jays. Two scrub-jay clusters are presently documented within the affected habitat area. These clusters, which are part of the south subpopulation, are composed of a total of seven (7) scrub-jay families concentrated primarily within Units 10 and 1 7 of Sebastian Highlands. Restoration and long-term management of the Unit 17 compensation areas, totaling 22:t acres of historically optimal scrub-jay habitat, are proposed under this HCP. This conservation area adjoins and is within 1000 ft. (305m) of five (5) scrub-jay families (Unit 17 cluster) that are potentially affected by the proposed action. The proposed restoration of the subject Unit 17 compensation areas is expected, over time, to minimize impacts to the affected Unit 17 scrub-jay cluster by maintaining suitable nesting and foraging habitat conditions for use by these scrub-jays. Under present-day conditions, only a small portion of the habitat areas used by the Unit 17 cluster would be classified as optimal scrub-jay habitat. To further minimize impacts to the affected scrub-jay clusters, restoration of the Unit 17 compensation areas is of the highest priority: A recent prescribed fire within the Pelican Island Elementary School scrub initiated the Applicants effort to minimize adverse impacts of the proposed action to this local scrub-jay population. An additional factor to be considered in quantifying the number of scrub-jay families anticipated to be affected by the proposed action is that loss of habitat within the Sebastian Highland lots is expected to occur incrementally, over time, as the City of Sebastian issues residential home construction permits towards build- out of the Sebastian Highlands subdivision. This further supports the need to prioritize habitat restoration measures within the Unit 17 compensation areas, Pelican Island Elementary School and Sebastian Highlands Scrub Conservation Area. Conservation measures to be implemented by the Applicants to mInimiZe and mitigate potential impacts of the taking, are the restoration and long-term management of optimal Florida scrub-jay habitat conditions within the combined 330.5::t acre Scrub-Jay Habitat Compensation Areas. The conservation strategies to be employed are outlined in the Sebastian HCP operating conservation program set forth below in Section 5.0 and are expected to result in a no net loss of scrub- jay families. 4.3 Analysis of the Effect of the Take on the North Indian River County/South Brevard County Metapopulation A discussion of the Sebastian HCP study metapopulation of which the Sebastian HCP study population is a part is presented above in Sections 2.1 and 3.2. It is also noted in Section 2.1, that the Scrub-Jay Habitat Compensation Areas proposed under this HCP incorporate the best and largest scrub parcels remaining within the HCP Plan 65 I- -~---- I I I I I I I I I I I I I I I I I I I Area. Therefore, the analysis of the effect of the proposed take and the corresponding sufficiency of the mitigation must consider the existing landscape constraints imposed on this HCP. The study population (Sebastian north and south subpopulations) is presently peripheral to the study metapopulation core located primarily in South Brevard County and extending south into the Sebastian Buffer Reserve expansions located Indian River County. Under present day conditions, extinction of both the north and south study subpopulations is certain without habitat restoration to optimal habitat conditions. Numerous studies conducted by Breininger et at. (1991, 1995, 1996a, 1996b, 1998a, 1998b, 1999) and others (Woolfenden 1974; Woolfenden and Fitzpatrick 1991; Schaub et at. 1992; Breininger et at. 1999) linking habitat features habitat use patterns and demographic success have shown that scrub-jay extinction risks are reduced in optimal habitat. Therefore, the proposed restoration of 324:t acres of predominantly poor quality scrub-jay habitat to optimal conditions and the provision of a critical mesic flatwood habitat linkage on Sebastian Airport properties is expected to enhance the persistence probability of this currently endangered scrub-jay population. However, as reflected in the operating conservation program (Section 5.0), restoration measures must be immediate and aggressive to reduce the current rates of decline documented within this scrub-jay population. Loss of the potential scrub-jay habitat identified within the ITP impact area, primarily Unit 17, may reduce the ability to maintain a contiguous Atlantic coast population; however the continuity of this population already appears unstable as a result of severe habitat fragmentation and poor quality scrub-jay habitat conditions that presently characterize the HCP Plan Area. The Sebastian north subpopulation will continue to be small and vulnerable to extinction because of low population size unless restoration strengthens the connection of this area to the Sebastian Buffer Reserve, as proposed under this HCP. The proposed HCP provisions of restoring an open landscape to facilitate dispersal between the north subpopulation and the Sebastian Buffer reserve and optimizing habitat quality on 236:t acres on the adjoining North Sebastian Conservation Area is expected to enhance the population persistence probability of the north subpopulation, and correspondingly, its contribution to the population size of the nearby study metapopulation. The Sebastian south subpopulation is vulnerable to extinction, particularly without implementation of the Sebastian HCP. Population persistence probability of the south subpopulation will always be low because of the severe fragmentation that now occurs for almost all of the Atlantic Coast scrub-jay population south of the north subpopulation. Therefore, the potential loss of two (2) scrub-jay clusters from the south subpopulation as a result of the proposed action is not expected to adversely impact the viability of the study metapopulation. The core populations critically important to the study metapopulation are located in south Brevard County (Breininger and Oddy 1 998). 66 I I I I I I' I I I I I I I I I I I I Ii J Restoration of the Unit 17 Pelican Island Elementary School/Sebastian Highlands Scrub Conservation Area, as recommended by the FWS as part of this HCP, should serve to minimize geographic isolation of the southern subpopulation. This will be accomplished by maintaining and enhancing the existing Unit 17 habitat linkage for the occasional dispersal of scrub-jays between the north and south subpopulation, and potentially, to the study metapopulation (FWS November 12, 1996 correspondence to Indian River County). The proposed long-term management of optimal scrub-jay habitat conditions at the Scrub-Jay Habitat Compensation Areas will serve to reduce cumulative effects of the proposed action. The vulnerability of the study population, especially the south subpopulation, to extinction, particularly without implementation of the proposed HCP is based on the following. Previous studies showed that dispersal tendencies by male Florida scrub-jays are short [mean = 984' (300 meters)] and that both sexes seldom move far during their lives in natural landscapes (Woolfenden and Fitzpatrick 1984, 1991). Dispersal distances are longer in fragmented landscapes, such as theHCP Plan Area (Thaxton and Hingtgen 1996; Breininger 1999). However, males appear to infrequently move among habitat fragments (Breininger 1999). The entire study metapopulation does not meet a patchy metapopulation structure where patches function as a single unit because many of the patches are not close enough for frequent dispersal by males, especially in the study populations (Harrison and Taylor 1987; Stith et al. 1996). Although, females might be the limiting factor in the entire metapopulation because of differential survival between males and females along the Atlantic Coast, males may become the limiting sex in many habitat fragments, especially residential landscapes (Breininger 1999). One can hypothesize that most habitat fragments not near other fragments will rarely be recolonized if all males expire in those fragments. Variation in patch habitat quality and size also prohibits the application of original metapopulation structure of extinction and recolonization theory (Levins 1 969) to describe Florida scrub-jay population dynamics. In large natural landscapes, Florida scrub-jays generally retain their territories and attract new replacement breeders following the death of their spouse (Woolfenden and Fitzpatrick 1984; Breininger et al. 1996a). This appears to be true for most study sites. However, in fragmented populations, females often move after th.e death of their spouse until they find a mate in another fragment (Breininger 1999). Typical source-and-sink theory does not always explain Florida scrub-jay dynamics in fragmented systems (Breininger 1999). Florida scrub-jays from small fragments that are sinks are temporarily sources of new breeders to larger fragments that can be sinks until no more jays are in population sinks (Breininger 1999). Thaxton and Hingtgen (1 996) reported that Florida scrub-jays nearly always moved from small suburban patches of low demographic success into larger reserve areas and not from large reserves into small habitat fragments'. Therefore, the type of 67 I! I I I I I I I Ie, I I: II __ I I I I I I I I metapopulation structure, where large reserves support many small reserves, may not predict Florida scrub-jay population dynamics. Another metapopulation structure (Harrison and Taylor 1997; Stith et al. 1996) proposed is a nonequilibrium structure where patches are too small and too far apart so that extinction is inevitable. This structure does not define dynamics of South Brevard metapopulation core because occupied patches are close together and there is an exchange of individuals. However, this metapopulation structure may accurately define the structure of most subpopulations south of the Sebastian study population. Implementation of the conservation measures set forth under this Sebastian HCP are expected to contribute, in the long-term, to the recovery of the fourth largest scrub-jay population across the remaining range. Proposed HCP actions will also serve to benefit other species of conservation concern residing within the Atlantic Coastal Ridge scrub landscapes covered under this HCP. 4.4 Alternatives Considered Three alternatives were considered by the Applicants to address the needs of the proposed action. Each alternative considered the biological requirements of the scrub habitat indicator species, the Florida scrub-jay, the legal mandates of the FWS, and the concerns of the Applicants with regard to resolving private land use conflicts in the Sebastian Highlands residential subdivision. 4.4. 1 Alternative 1: No Action Alternative Under Alternative 1, the FWS would not issue the ITP to the Applicants, and the Applicants would not implement proposed habitat management and restoration actions on 330.5:t acres of publicly-owned lands for purposes of enhancing Florida scrub-jay demographic success by optimizing habitat suitability and by facilitating dispersal and recolonization of restored and uninhabited habitat. Individual owners of the one-quarter acre lots located within the platted residential areas of the Sebastian Highlands subdivision that are currently, or in the future, designated by the FWS as potentially occupied by Florida scrub-jays would be unduly encumbered by preparation of an individual HCP to construct a single-famil.Y residential home or would risk exposure to a violation of Section 9 of the ESA if they initiated construction without an ITP. The City of Sebastian would also risk exposure to Section 9 violations if this local government issued clearing or building permits for residential home construction that was subsequently determined to have resulted in the "taking" of Florida scrub-jays. If the individual Sebastian Highlands lot owners decided not to construct, then they would have great. difficulty selling their lots at fair market value due to imposed ESA constraints to development. Issuance of multiple individual HCPs' would result in piecemeal 68 I I I I I I I I I I I I I I I I I I I mitigation by leaving small "hedgerows" of vegetation on each lot since the individual lot owner likely could not afford to contribute funds for the purchase of scrub within a FWS approved Florida scrub-jay mitigation area. Preservation of small IIhedgerows" of vegetation on individual lots are not as efficient, manageable, or viable for scrub-jay persistence as comprehensive mitigation and management actions on larger, more contiguous tracts of habitat. If mitigation funds were collected from individual Sebastian Highlands lot owners, they would probably be directed into Brevard County since the FWS has not identified an acceptable Florida scrub-jay mitigation area in Indian River County due to the high-level of habitat loss, degradation, and fragmentation presently characterizing this area. Potential environmental consequences of the No Action Alternative would be relatively minimal the short-term because no additional scrub-vegetated lots would be cleared. However, the benefits of protecting the existing scrub-jay families within the severely fragmented Sebastian Highlands residential subdivision landscape are expected to be short-term. This is due to continued degradation of habitat quality due to the inability to adequately manage preserved habitat patches, and to increased vulnerability of the scrub-jay population to road mortality and to predation by species common to suburban environments, such as blue jays, fish crows, boat-tailed grackles (Ouiscalus major), common grackles (0. quiscula), raccoons, and house cats (Fitzpatrick et al. 1991; Breininger 1999). Fitzpatrick et al. (1991) reported that vehicular traffic through scrub-jay habitat significantly increases the mortality rate within a population of scrub-jays. Scrub-jay survival rates adjacent to highways were significantly lower (0.57) than that found in scrub- jay territories lacking paved roads (0.79) (Fitzpatrick et al. 1991). Long after scrub- jays have become habituated to major traffic thoroughfares, their low-altitude flight profile makes them vulnerable to collisions with vehicles (Breininger unpubl. data; Toland unpubl. data). Management of optimal scrub-jay habitat conditions within the currently fragmented scrub patches located within the residential lots of the vast Sebastian Highlands subdivision through prescribed fire would be significantly constrained by the proximity of the residential homes. Fire is essential to maintaining optimal scrub-jay habitat conditions (Woolfenden and Fitzpatrick 1991; Meyers 1990, Schmalzer et al. 1994; Breininger et al. 1996b). The documented decline of Florid.a scrub-jay populations is attributed to poor habitat quality resulting from disruption of natural fire regimes (Breininger 1999; Breininger et al. 1995, 1996a, 1996b, 1998b, 1999; Fitzpatrick et al. 1991; Woolfenden and Fitzpatrick 1984). Although the application of mechanical cutting techniques can successfully reduce the height of the scrub vegetation and create openings preferred by scrub-jays, mechanical treatments have not been found to be a substitute for fire in the long-term management of optimal scrub-jay habitat conditions (Schmalzer et al 1 994; Woolfenden and Fitzpatrick 1991). Without fire management, the fragmented scrub 69 I j I I I I I I I I I I I I I I I I I I I project. Even as a stand alone project, the SSCA would have served to reduce the extent of take and to enhance scrub-jay conservation efforts in the City of Sebastian, thereby alleviating much of the conflict surrounding private development in the platted Sebastian Highlands lots (FWS, February 7, 1995 correspondence to Indian River County; September 11, 1996 Indian River County Memorandum). In July 1996, the IRC Board approved the purchase of "Phase 1" of the SSCA project lots. This consisted of 50 of the 56 lots owned by AGC (September 11, 1996 Indian River County Memorandum). In September 1996, the Indian River County planning staff recommended that the IRC Board authorize purchase of "Phase II" of the SSCA project comprising of 47 lots with 47 different owners. The high quality scrub habitat contained within the Phase II of the SSCA project is highly fragmented by a mosaic of occupied single-family houses and cleared, one- quarter-acre lots with many different owners. The tax assessed value of the subject one-quarter acre lots averaged $8,445.00 or $33,780.00 per acre (September 11, 1996 Indian River County Memorandum). An additional cost to Indian River County for the Phase II SSCA project was a $52,658.96 water line utility assessment. Total 50% cost share of the Phase II SSCA project, including appraisals and audits, was $266,109.00 for 11.75 j: acres of highly fragmented scrub-jay habitat acre (September 11, 1996 Indian River County Memorandum). This represents an extremely expensive conservation acquisition effort. Appropriate management of the fragmented, urban scrub using controlled burns wbuld have been problematic due to liability and potential adverse effects of smoke on nearby residents. The alternative, scrub management via mechanical strategies, is an expensive management strategy, especially in a suburban setting, because it is labor intensive and requires negotiating heavy equipment. In addition, the long- term effects of mechanical management actions to the scrub plant community are not fully understood and must be used carefully (Schmalzer et a/. 1,999). Even more significant, per acre management costs for maintaining or restoring remnant scrub in suburban areas, are comparatively more expensive than habitat management prescriptions on large parcels of land in undeveloped scenarios. In consideration of the multiple project constraints and limitations listed above, and at the recommendation of the Indian River County Land Acquisition Advisory Committee (LAAC), the IRC Board voted in September 1996 to reject the acquisition of Phase II of the SSCA project. This decision halted all acquisitio.n efforts by Indian River County of the Sebastian Highlands Unit 17 platted lots comprising the SSCA (Indian River County, October 17, 1996 correspondence to the FWS). At the subsequent urging of the FWS, Indian River County did complete the purchase of a block of 34 contiguous lots in Unit 17. The FWS stated that the "... 34 AGC lots, in combination with Pelican Elementary School scrub, may provide enough suitable habitat to minimize the adverse effects of habitat fragmentation due to losses in the remainder of Unit 17. These scrub parcels, if properly managed, may be essential "stepping stones" for dispersal of scrub-jays 73 ~ I, 1 1 1 1 1 1 1 1 1 1 1 1 1 1 I 1 I I from and to northern Indian River County..." (FWS, November 12,1996 correspondence to Indian River County). These 34 AGC lots, referred to herein as the Sebastian Highlands Scrub Conservation Area were acquired by Indian River County and are included in combination with the Pelican Island Elementary School scrub as part of the proposed Sebastian HCP Scrub-Jay Habitat Compensation Areas located in Unit 17 of Sebastian Highlands. Implementation of Alternative 3 may have served to increase population persistence probability of the south subpopulation, however the persistence probability of this subpopulation will always be low because of the extensive fragmentation that presently characterizes this area. Appropriate management of optimal scrub-jay habitat conditions within the fragmented scrub lots would have been extremely difficult due to the multiple residential homes adjoining the SSCA project area. Alternative 3 was determined to be infeasible due primarily to economic and habitat management constraints imposed by present-day conditions. 74 1 1 I' 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 5.0 SEBASTIAN HCP OPERATING CONSERVATION PROGRAM The Sebastian HCP operating conservation program set forth herein provides conservation measures to be implemented by the Applicants to minimize and mitigate potential adverse impacts of the incidental take on occupied and potential Florida scrub-jay habitat and associated listed species to the maximum extent practicable. The biological goals and objectives for the Sebastian HCP operating conservation program are as follows: BIOLOGICAL GOALS The biological goals defined below represent the overall guiding principles for the Sebastian HCP operating conservation program. 1. Reduce extinction risk and increase population persistence probability of the Sebastian HCP study population, composed of two (2) subpopulations, by restoring and permanently managing optimal Florida scrub-jay habitat conditions, as described in Breininger et al (1995, 1996b), in 324:1: acres of Florida scrub-jay focal and matrix habitat identified as the Scrub-Jay Habitat Compensation Areas and presently owned by the Applicants. 2. Enhance recovery potential of the North Indian River County/South Brevard County metapopulation, the fourth largest Florida scrub-jay meta population (Breininger and Oddy 1998) I by restoring and maintaining, in the long-term the 6.5:t acre Sebastian Airport dispersal corridor tract as an open mesic flatwood landscape linkage between the Sebastian HCP study population and the study metapopulation clusters located on the St. Sebastian Buffer Reserve. Enhance dispersal success by managing the adjoining 88.1 :t acres in the interim prior to commercial development and by managing, in the long term, a narrow hedgerow located between the golf course and the southern runway to a maximum veget~tive height of about 6' (2m). 3. Protect the biological integrity and species diversity that is characteristic of the Atlantic Coastal Ridge scrub ecosystem by returning the combined 330.5:t acre Sebastian HCP Scrub-Jay Habitat Conservation and Corridor Compensation Areas to conditions representative of the historical landscape and thereby optimal for native species of conservation concern adapted to open landscapes subject to frequent fires. . BIOLOGICAL OBJECTIVES The biological objectives presented below represent specific measurable actions that must be implemented to achieve the above stated biological goals. 75 I I I I I I I I I~ I I I I II I I I I I D. A. Implement mechanical and restoration burning strategies, as set forth in Section 5.3, immediately to initiate recovery of optimal Florida scrub-jay habitat quality features within the' 330.5:!:: acre Sebastian HCP Scrub-Jay Habitat Conservation and Corridor Compensation Areas. Apply mechanical treatments to reduce the tree canopy, cover to less than 15% (1 to 2 trees per acre) and to eradicate the exotic pest plant, Brazilian pepper. Use logging operations as the primary mechanical technique to thin pine trees and to fell tree-sized (> 3.0 in. diameter at breast height (dbh)) scrub oaks and cabbage palms. Use the Cut Stump herbicidal control method to remove Brazilian pepper for the targeted conservation sites. Initiate an aggressive restoration burning program, within six (6) to eight (8) weeks from completion of mechanical treatment on the initial conservation site, or as soon thereafter as suitable weather conditions permit, to reduce shrub height, consume vegetative debris left on the ground from applied mechanical treatments, and initiate recovery of open areas. B. Implement a habitat management program that uses prescribed fire as the primary management tool to maintain, in the long-term, optimal Florida scrub-jay habitat quality features within the Scrub-Jay Habitat Compensation Areas. Integrate habitat management principles that favor maintenance of the biological diversity that is characteristic of the Atlantic Coastal Ridge scrub ecosystem, and thereby optimal for Florida scrub-jays, by promoting variation in management unit size and location, fire frequency (based on scrub-jay habitat quality structural criteria), fire intensity, fire patchiness, and timing of burns (favoring natural season burns) (Schmalzer et at. 1999; Main and Menges 1997; Breininger and Oddy 1998). The presence of optimal Florida scrub-jay habitat features, as defined in Breininger et at. (1995, 1996b) and described above in Section 2.4.1, will generally be used by the Applicants to measure achievement of this biological objective at the landscape scale at each of the Scrub-Jay Habitat Compensation Areas. C. Establish a comprehensive monitoring program, referred to herein as the Sebastian HCP Habitat Management Monitoring Program, that annually, for the term of the ITP, ascertains the success of the applied mechanical and fire management treatments in achieving the stated biological objectives. Use the collected site-specific monitoring data, in conjunction with state-of-the- science habitat management principles and resources to refine and improve future management actions. Explore the potential of establishing an inter-agency partnerships with the FWS, FWC, and/or FDEP, and/or obtaining additional funding through grants, 76 1 1 I' for acquisition of additional scrub habitat as presently proposed by the Pelican Island Elementary School Eco-Troop. Additional funds could also be applied to support implementation of a comprehensive colorbanding and demographic study of the study population. Performance of this study would serve to augment demographic studies currently being conducted in South Brevard County to facilitate recovery of the North Indian River County/South Brevard County meta population of which the study population is a part (Breininger and Oddy 1 998). The Dynamac Corporation is performing the South Brevard study with contract funds provided by the FWS Jacksonville, Florida (Breininger and Oddy 1998). 1 1 1 1 1 1 1 1 1 I 1 1 1 1 1 1 5.1 Habitat Management Considerations .~ j The sedentary characteristic of Florida scrub-jays has a significant influence on their large-scale population structure, and must be a consideration of any habitat protection measure targeted towards protection of this species (Woolfenden and Fitzpatrick 1 991). Because most scrub-jays become breeders within a few hundred meters of their natal territory, they ensure that protected patches of suitable scrub routinely pass among generations without requiring new colonization events (Woolfenden and Fitzpatrick 1984, 1991). Persistence of small subpopulations of scrub-jays is enhanced if located within the normal dispersal radius, two (2) miles or less, of neighboring scrub-jay subpopulations (Woolfenden and Fitzpatrick 1 991; Fitzpatrick et al. 1 994a). Therefore, the conservation and management of tracts of suitable scrub- jay habitat located between large habitat patches, referred to as "stepping stone" scrub, provide vital links to scrub-jay populations (Fitzpatrick et al. 1994a). It is important that these intervening habitat patches are managed for optimal scrub-jay habitat conditions as mortality associated with dispersal is high for scrub-jays moving through small woodlands, urban areas, and open agricultural areas (Stith et al. 1996). Clusters of small to intermediate-sized subpopulations may ,be the optimal configuration of Florida scrub-jay metapopulations where the total area of conserved habitat is limited or fragmented (Woolfenden and Fitzpatrick 1991). The above biological criteria were considered by the FWS in developing the scrub-jay core habitat reserve design for the City of Sebastian (Toland 1996). This reserve design essentially directed the acquisition and designation of the presently-owned Sebastian HCP Scrub-Jay Habitat Compensation Areas. Suitable scrub-jay habitat is not restricted to. scrub oak patches (Breininger et al. 1991, 1995, 1996b, 1998a; Duncun et al. 1995). Scrub-jays defend and use mesic habitat types, such as open pine flatwoods and saw palmetto scrub, located near oak scrub patches (Breininger et al. 1995, 1998a). Alteration and fragmentation of the matrix habitat by development/agricultural activities disrupts fire patterns, alters prey and predator composition, and removes habitat that may become optimal after fires (Fitzpatrick et al. 1991; Breininger et al. 1995; Breininger and Oddy 1998). Therefore, management of optimal scrub-jay habitat conditions must consider the matrix habitat 77 I I I I I I I I I I II I I I I I I I I_H] in which the focal scrub patches are embedded (Breininger and Oddy 1998). Management of the matrix habitat serves to benefit associated scrub species, such as the gopher tortoise, Eastern indigo snake,' and wetland dependent species, including the threatened Florida gopher frog (references in Breininger and Oddy 1998; Schmalzer et a/. 1 999). Management of the depression marshes provides breeding sites for amphibians which form a significant portion of the food chain; insuring an important food source to Florida scrub-jays (Breininger and Oddy 1998; Schmalzer et a/. 1 999). Where natural fire processes have been restricted by anthropogenic barriers or activities, the scrub oaks often reach a size that is essentially fire-resistant (Guerin 1988,1993; Schmalzer et a/. 1 994). Restoration of tall, unburned scrub to optimal Florida scrub-jay habitat conditions usually can not be achieved by fire alone, as the tree-sized scrub oaks are able to survive fire and resprout from trunks above ground (Schmalzer et al. 1994). The objective to restore a low, open habitat structure would not be accomplished as the overgrown scrub would regenerate as a forest structure (Schmalzer et a/. 1994). Therefore, mechanical cutting of the tall fire-resistant scrub oaks, followed by a prescribed fire, has been found to be the only reasonable method of restoring severely degraded scrub communities (Schmalzer et a/. 1994). This method has been used at both Oscar Scherer State Recreation Area (Smyth 1 991 ) and Kennedy Space Center (KSC) (Schmalzer et a/. 1994, 1999) for the purposes of restoring suitable scrub-jay habitat conditions. Scrub-jays exhibit a dramatic preference for recently burned or mechanically disturbed scrub, defending and foraging in these patches unless the land management treatments affect all or most of the defended territory (Fitzpatrick et al. 1 994a). Studies at KSC found that scrub- jays actively use restored area for foraging, caching acorns, and even nesting within 18 months post-fire (Breininger et a/. 199Gb). Although mechanical treatments are successful in reducing vegetation height and creating openings in the scrub, they should be applied carefully to reduce the potential for soil disturbances and a discontinuity of fuels (Breininger and Schmalzer 1 990). Mechanical treatments may reduce the post-treatment coverage by saw palmetto if damage to the saw palmetto rhizomes is severe (Schmalzer et a/. 1 999). As saw palmetto is the primary species for carrying fire in Atlantic Coastal Ridge scrub landscapes, reductions in the coverage of this species can alter the ability to successfully apply prescribe fire as a habitat management tool (Schmalzer et al. 1999) . Fire is vital to and influences many natural community processes that can not be replicated by mechanical treatments alone. Fire provides readily available nutrients to new growth and surviving plant life through direct release of mineral elements as ash. It regulates fuel loadings and production by the recycling of woody plant components and consumption of leaf litter and humus layers. Scrub-jays prefer to forage in open conditions without litter (Schmalzer et a/. 1994). Mechanical treatments in scrub leave behind an unnatural amount of debris on the ground. Fire also affects the 78 I I I I I I I I I I I I I Ii I I I I I' I reproductive processes of many plant species, often stimulating seed release, flowering, and vegetative growth. Most scrub researchers agree that, although mechanical treatments are an important 'method for restoration of scrub that has become fire-resistant due to overgrowth, scrub should be managed, in the long-term, by prescribed fire (Fitzpatrick et aI, 1 991; Schmalzer et al. 1994, 1 999; Breininger et al. 1996b). Establishment of a fire regime for management of optimal habitat conditions for scrub-jays must be based on site-specific factors due to variability in the community dynamics of scrub habitat types (Schmalzer and Hinkle 1992; Schmalzer and Boyle 1997). Fitzpatrick et al. (1991) suggests that the fire-return interval for individual patches of oak scrub is 10-20 years. This return interval is consistent with optimal scrub height classes (Breininger et al. 1995, 1996b). Scrub height models have been developed from data on scrub recovery after fire. These models predict that oaks grow to 3.9' (1.2m) within 10 years after a fire, and that oaks grow taller than 5.6' (1.7m) within 20 years of a fire' (Duncan et al. 1995). The response of oak scrub to fire varies because of differences in soils, nutrients, water table, and previous fire history (Abrahamson and Hartnett 1 990; Breininger and Schmalzer 1990; Myers 1990; Schmalzer and Hinkle 1992; Menges and Kohfeldt 1995; Hawkes and Menges 1996). Research at KSC has found that scrub oaks can occasionally grow to 3.9' (1.2m) within a few years (e.g., 3 years), especially in areas previously unburned for > 20 years (Breininger unpubl. data; Schmalzer and Boyle unpubl. data). Scrub can also become taller than optimal within 5 - 10 years after fire (Breininger unpubl. data), therefore some scrubs may require shorter fire intervals. Florida scrub-jay territories include not only oak scrub habitat, but also the surrounding matrix habitat types composed of mesic flatwoods and grassy areas which are often wet (Breininger et al. 1991, 1995). Saw palmetto, gallberry holly, and grasses (e.g., Aristida stricta, Spartina bakenl, which dominate mesic flatwoods and marshes, are more flammable and accumulate fuel more rapidly than scrub oak habitats (Abrahamson 1984; Abrahamson and Hartnett ,1990; Myers 1990; Schmalzer et al. 1991; Schmalzer and Hinkle 1992). Mesic flatwoods and grassy areas have a fire-return interval of 1 - 10 years (FNAI 1990). Therefore, long-term habitat management strategies will need to consider frequent fires for matrix habitats surrounding oak scrub to maintain an open landscape structure optimal for scrub-jays and to reduce the accumulation of fuels that lead to hazardous fire ,events (Breininger et al. 1996b). Because site variability influences recovery from fire, natural resource managers should use height, openings, pine cover, and other structural features to assist in determining burning objectives for a particular site. Fitzpatrick et al. (1 991) suggested that a fire management program for Florida scrub-jays is best if a rotation of prescribed burns occurs where each burn covers only small portions of the reserve tract. Studies conducted at KSC confirm that 79 ,- --- I I I I I II I I Ie I I I I I I I I I !I I frequent fires that do not burn all of a territory are essential for maintaining Florida scrub-jay populations (Breininger et al. 199Gb). Single burns in scrub landscapes at intervals longer than 5 years could result in extinction of Florida scrub-jay populations (Breininger et al. 199Gb). The presence of patches of tall oaks greater than 1 acre (0.4 hectare) in size had negative impacts on demography (Breininger and Oddy 1998). Large (e.g., 1 acre) or wide [> 328' (100 m)] patches of tall shrubs may interfere with the jay's visual sentinel system, which is adapted for predator detection and territorial defense (McGowan and Woolfenden 1989). A few small clumps of tall oaks will not interfere with visibility and can serve as useful posts for sentinels. Analyses of sequences of aerial photographs indicate that many scrub and grassy areas have become forests and that most remaining scrub has lost openings among the oaks (Duncan et al. 1999). The reduction in availability of openings has resulted in the rigorous competition by Florida scrub-jays for areas with openings (Duncan et al. 1995; Breininger et al. 1998b). Few openings remain in scrub 1 - 2 years after fires (Schmalzer and Hinkle 1992). Scrub oaks became established in most openings, and 20 years of prescribed burning that followed fire suppression has not yet produced an a~undance of openings (Schmalzer et al. 1994; Duncan et al. 199G; Breininger et al. 1 998b). It may take many fires to establish the openings that are critical for long-term Florida scrub-jay population persistence. Open sandy areas are also believed to be important to other scrub plants and ~nimals (Campbell and Christman 1982;. Hawkes and Menges 1996). In the past, many prescribed fires have occurred in winter, which may partially explain why natural openings have not returned. Winter fires do not reduce oak cover as effectively as growing-season fires (Glitzenstein et al. 1995). Most natural fires occurred during the growing season, and scrub is ada,pted to growing- season fires (Robbins and Myers 1992). Single growing season fires have been found not to result in openings that last longer than one (1) to two (2) years (Breininger unpublished data). Many growing-season fires may be needed to restore openings to scrub that was unburned for> 20 years. Although there appear to be no plant species specially adapted to long-unburned scrubby flatwoods, some xeric scrubs have species adapted to longer fire intervals (Menges and Kohfeldt 1995). Some native scrubs, dominated by sand pine (Pinu.s clausa) or rosemary (Ceratiola ericoides), need longer fire rotations (> 20 years) and naturally occurred in locations less susceptible to fire (FNAI 1 990; Menges and Kohfeldt 1995). To maintain species diversity, management of scrub and flatwoods cannot include an arbitrary mixture of habitat patches of different ages since the last fire. Florida scrub-jay populations probably cannot persist where tall scrub (> 20 years since fire) is interspersed with short or optimal height scrub at the territory scale (Breininger unpubl. data). Only the largest Florida scrub-jay populations can persist for 50 years once most habitat becomes suboptimal 80 I I I I I I I I' I I I I I I I I I I I (Breininger et al. 1996b). Most Florida scrub-jay populations have become small and fragmented (Stith et al. 1996), such as the Sebastian HCP study population, and will require site-specific attention by natural resource managers. 5.2 Potential Effects of Habitat Restoration and Management Treatments on Other Species of Conservation Concern Fire is the preferred management tool for restoration and the long-term maintenance of scrub communities as optimal Florida scrub-jay habitat (Fitzpatrick et al. 1991; Breininger et al. 1996b), as it prevents the succession of suitable low, open scrub into an unsuitable closed canopy forest and reduces the potential for soils disturbances and the creation of fuel discontinuities (Breininger et al. 1996b). Fire generally has little adverse direct effect on scrub species as they have developed adaptations to fire (Myers 1 990). Management of habitat conditions that are suitable for scrub-jays are suitable for most other amphibians, reptiles, birds, and small mammals occurring in the scrub (Schmalzer et al. 1994; references in Breininger and Oddy 1998). No protected species are known to require unburned scrub or pinelands (Schmalzer et al. 1 994). No federally listed plants are documented to occur in the scrub-jay habitat types on the Scrub-Jay Habitat Compensation Areas (FWS 1999, FWS unpubl. data). As the scrub ecosystem depends on periodic fires, most of the native scrub plant species will benefit from reintroduction of a natural fire regime (Schmalzer et al. 1 994). The potential of the proposed mechanical treatment to cause adverse impacts to gopher tortoises and commensal species documented to occur on the Scrub-Jay Habitat Compensation Areas is low. Wherever possible, the individual fire management units delineated within the Scrub-Jay Habitat Compensation Areas will use existing jeep trails and historic fire breaks as "hard" lines to con.trol the spread of fire. Studies of the effects of forestry operations, such as timbering, have shown that gopher tortoises have the ability to dig out from collapsed burrows (Joan Berish, FGFWFC in Schmalzer et al. 1 994). Every effort will be made to avoid gopher tortoise burrows during implementation of the recommended mechanical restoration activities. 5.3 Sebastian HCP Florida Scrub-Jay Habitat Restoration and Management Program (HCP Management Program) The HCP Management Program identifies specific management activities to. be undertaken by the Applicants to proceed towards achievement of the stated biological goals and objectives of this HCP. The HCP Management Program consists of two phases. Phase One represents the restoration of poor quality scrub-jay habitat conditions using mechanical treatment and prescribed fire management strategies. Phase Two consists of long-term management practices that focus on maintenance of optimal Florida scrub-jay habitat conditions through the use of periodic prescribed fire. 81 I~-- - ~--~ , II I I I I I I- I I- I I I I I I I I :1 II Prior to the extensive habitat fragmentation which now characterizes much of the present-day landscape and functions as fire barriers, fires were ignited by lightning primarily during the late spring and summer months and burned large expanses across the landscape (Robbins and Myers 1992), The frequent lightning fires resulted in an open landscape with few forests; conditions which were historically represented in the scrub landscape at each of the Sebastian HCP Scrub-Jay Habitat Compensation Areas, As scrub requires fire to maintain its characteristic low, open habitat structure; scrub restoration and management strategies must also depend on fire as the primary management tool to perpetuate native scrub habitat conditions (Woolfenden and Fitzpatrick 1984, 1991; Schaub et al. 1992; Breininger et al. 1995, 1998a; Duncun et al. 1995; Breininger and Oddy 1998; Breininger 1999). As presented above, the long-term exclusion of fire from scrub communities results in a habitat that essentially becomes difficult to burn (Schmalzer et al. 1 994, 1 999) and/or control without prior mechanical treatment of the dense canopy stratum (Breininger et al. 199Gb). Therefore, the use of aggressive management actions, such as mechanical thinning of the pine canopy by logging activities using timber sales, will be employed to expedite the restoration of optimal Florida scrub-jay habitat conditions within the Sebastian HCP Scrub-Jay Habitat Compensation Areas, However, this treatment method must be careful not to result in excessive soils disturbance, Excessive soils disturbance can result in reduced coverage by saw palmetto scrub and, thereby, may reduce the ability to conduct future burns (Breininger and Schmalzer 1990, Duncun et al 1999). Soils disturbances also provide recruitment sites for exotic pest species, such as Brazilian pepper, Timber management (sales) as a scrub-jay habitat restoration strategy involves the reduction of tree densities to levels that are favorable for the Florida scrub-jay, e.g. an average of one (1) to two (2) pines per acre (Breininger pers comm.). In the few areas of the Scrub-Jay Habitat Compensation Areas where large diameter scrub oaks occur, the timber contractor will be directed to also cut these trees. Smaller diameter pines left by the logging operation can be reduced by increasing fire frequencies in these areas (Breininger pers. comm.). The use of increased fire frequencies during the restoration burning period also has the positive effect of initiating the restoration of openings in the scrub and reducing shrub height (Breininger et al. 199Gb), Restoration of open spaces in the scrub habitat can also be achieved by allowing downed trees to burn (Breininger et al. 199Gb). This use of this habitat management technique may be restricted within the Scrub-Jay Habitat Compensation Areas due to the potential' to create smoke problems along the urban interfaces of these sites, primarily U.S. Highway 1, C.R. 510, and the internal thoroughfares of Sebastian Highlands, It will be the responsibility of the prescribed burn manager for the Sebastian HCP Management Program to determine the safety of using this management technique to recover open spaces within the subject scrub restoration areas. 82 1 1 1 1 1 1 I~ 1 1 I~ 11 I: 1 I 1 1 1 1 I Whenever possible, prescribed fires will be conducted during the natural fire season, late spring and summer, to mimic historic fire patterns (Breininger et a/199Gb; Adrian and Farinetti 1995). Knowledge of the location of critical scrub-jay nesting sites and the extent of each scrub-jay territory will enhance efforts to conduct prescribed burns during these months while reducing the potential for occurrence of adverse impacts to the resident scrub-jay population. As a measure to minimize adverse impacts of the scrub restoration on scrub-jays, the Applicants will conduct field surveys prior to the application of prescribed fires within a scrub-jay territory during the nesting season. Prescribed fire frequency, following the initial burns, will be dictated by habitat quality data collected as part of the site-specific Sebastian HCP Habitat Management Monitoring Program (HCP Monitoring Program). The time between burns will be limited by the availability ratio of dead to live fuels (Breininger et a/. 199Gb). Effective fires appear to require that 25 % of the above ground biomass be composed of dead fuels (F. Adrian pers. obs. in Breininger et a/. 199Gb). A minimum of 2~ years may be required between burns within matrix flatwoods habitats characterized by a dense saw palmetto cover (Breininger et a/. 199Gb). Oak scrub habitats exhibiting a sparse cover of saw palmetto may require a minimum of 3-5 years between burns (Breininger et a/. 199Gb). Variability is an important ecological component that must be integrated into any fire management program (Christensen 1985; Schmalzer and Hinkle 1992; Fernald 1989). Regular prescribed burn management schedules place constraints on the habitat managers and reduces habitat heterogeneity (The Nature Conservancy (TNC) 1 991 ; Schmalzer et a/. 1 999). Flexibility in management schedules, as proposed herein, allows the land manager to refine future burn units, treatments, and schedules based on the effectiveness of previous burn prescriptions in achieving the management goals (TNC 1991; Schmalzer et a/. 1999). 5.3.1 Identification of land Manager and Prescribed Burn Manager The IRC Board hired a Conservation lands Manager on January 2G, 2000 (R. DeBlois pers. comm.). It will be the responsibility of the Conservation lands Manager, in conjunction with the County Environmental Planning Section, to coordinate implementation of HCP Management Program and performance of the HCP Monitoring Program. The prescribed burning program for the Sebastian HCP Scrub-Jay Habitat Compensation Areas will be coordinated through and, conducted by, the State of Florida Department of Forestry (OaF) in agreement with Indian River County (R. DeBlois pers. comm.). The OaF will be responsible for preparing the actual burning prescriptions for each management unit guided by the biological goals and objectives of this operating conservation program and the specific restoration burning and fire management objectives outlined below. The prescription must also consider the 83 I I I I I I I I I- I 1- , I- I- I I I I I, II J vegetative type and fuel load, smoke management and site constraints, and proximity to neighbors. Indian River County will be responsible for coordinating with the OOF to notify nearby public and private entities of the intent to burn before and after the burn permit is issued. Public notification is strongly recommended for all prescribed burns conducted on the Scrub-Jay Habitat Compensation Areas. A short broadcast on local radio stations is recommended to caution motorists on nearby thoroughfares, such as C.R. 510, U.S. Highway 1, and Roseland Road, of the possibility' of smoke affecting visibility. Additional efforts shall also be made to notify local community residents about the burn. In addition, a brief educational bulletin should be circulated to nearby residents informing them as to the importance of fire in maintaining suitable scrub habitat for the Florida scrub jay and other scrub species of conservation concern.' Public education will be critical for local support of the Sebastian HCP Management Program that is centered on the ability to apply fire to the scrub landscapes within the Scrub- Jay Habitat Compensation Areas. 5.3.2 Phase One - Habitat Restoration Activities - Mechanical Treatments and Restoration Burnina Habitat management needs for the Scrub-Jay Habitat Compensation Areas are defined on Tables 5 and 6. Review of this information shows that majority of the potential scrub-jay habitat identified in the Scrub-Jay Habitat Compensation Areas needs immediate pine thinning and the application of hot fires. The location of each designated habitat pOlygon is provided on Figures 5, 7, and 9. Optimal scrub-jay habitat conditions on the Scrub-Jay Habitat Compensation Areas are currently limited to a small xeric oak patch (Polygon 14) located in the North Sebas~ian Conservation Area, the northern section of the Wabasso Scrub Conservation Area (Polygon 50), and a small xeric oak patch (Polygon 44) within the Pelican Island Elementary School compensation area. The Sebastian HCP study population is documented to be declining primarily because of habitat loss and poor habitat quality of the remaining scrub fragments (Toland unpubl. data). Based on numerous studies as cited above, aggressive restoration and management can correct the poor habitat quality that has resulted from fi~e suppression ,within the Scrub-Jay Habitat Compensation Areas. However, the restoration process must be implemented immediately to reduce the current rate of scrub-jay population decline. 5.3.2.1 MECHANICAL TREATMENTS Initial management efforts towards restoration of optimal scrub-jay habitat conditions on the Scrub-Jay Habitat Compensation Areas will employ two (2) mechanical 84 ~ I I I I I I I 11 _ I I I I I I I I I I I management techniques. Table 7, Florida Scrub-Jay Habitat Restoration Activities - Mechanical Treatments, outlines the habitat polygons to be treated by mechanical treatment methods, the initial implementation schedule, and a site priority ranking for treatment initiation. As discussed above in Section 4.2, Pelican Island Elementary School and Sebastian Highlands Conservation Area sites (Unit 1 7 compensation areas) have received the highest priority ranking as a measure to minimize the extent of take within the surrounding ITP impact area by quickly providing suitable habitat for use by the resident scrub-jay clusters potentially displaced by residential construction. Restoration of the Sebastian Airport dispersal corridor has been ranked second to encourage dispersal between the study population and scrub-jay clusters located on the nearby St. Sebastian Buffer Reserve (Coraci Parcel). This priority ranking is mirrored in the restoration burning implementation schedule provided below. The mechanical treatments to be applied within each habitat polygon are specified on Table 7 and include one or both of the following: 1 . Thinning of pine trees, slash pine and sand pine, and snags by logging activities using timber sales, to reduce the total canopy cover to 1 to 2 trees {live trees and snags} per acre. The total number of standing timber (live and dead) shall not exceed a maximum of 1 to 2 units per acre. The standing trees/snags will be maintained to provide resident scrub-jays with sentinel perches and potential arboreal cache sites. Where present, dense stands of cabbage palms and large diameter oaks will be removed from the habitat polygon by the timber contractor so that the canopy cover, considering all tree species in the canopy stratum, does not exceed the above density criteria. The resulting canopy in the mesic flatwoods can be a mixture of pine and cabbage palm not exceeding 1 to 2 trees per acre. NOTE: To reduce the negative influence of the surrounding degraded habitat structure on the quality of the habitat areas targeted for restoration on the Scrub-Jay Habitat Compensation Areas, it is recommended, although not considered a regulatory requirement covered under this Hep, that the logging operation extend into all upland habitat types occurring within the boundaries of the 406:i: North Sebastian Conservation Area (Polygons 1 0, 11, and 21) an.d the Sebastian Airport/Golf Course complex and the Wabasso Scrub Conservation Area (Polygon 54). 2. Removal of exotic and nuisance species. This directive is primarily targeted at the Brazilian pepper that has colonized within the North Sebastian Conservation Area along the disturbed edges of historically paved roads and jeep trails. The height of the Brazilian pepper presents a potential curtain between contiguous scrub-jay families. 85 I' I I I I I I I I I I I I I I I I I I Table 7.

I I I I I I I I I I I I Restoration Burning The restoration burning approach presented herein is aggressive as compared to the general guidelines for managing Florida scrub-jay refuges provided in Fitzpatrick et al. (1991). However, aggressive management is needed in the Scrub-Jay Habitat Compensation Areas before there is further loss of additional scrub-jay families. The MUs and proposed prescribed burn schedule are designed to insure that each scrub- jay family documented to occur on the Scrub-Jay Habitat Compensation Areas are provided with an adequate amount of suitable cover, nesting sites, and foraging habitat while the recently-burned scrub regenerates. Prescribed fire will initially be used at increased frequencies and intensities to reduce pine tree cover remaining after completion of the proposed logging operation, to reduce shrub height, and to initiate recovery of patchy open spaces of bare sand and sparse vegetation. The prescribed fires will, whenever practicable considering site and safety constraints, be conducted during the natural fire season, late spring and summer, to mimic historic fire patterns (Breininger et al 1996b; Adrian and Farinetti 1995). The schedule for implementation of prescribed fire within each MU, including a site priority ranking and recommended fire intensity, is provided in Table 8. Site-specific fire prescriptions required to achieve the stated prescribed fire management objective will be prepared by the OaF as part of their agreement with the Applicants. The OaF will also be responsible for identifying and addressing constraints to conducting the prescribed burning operation on the Scrub-Jay Habitat Compensation Areas and, with the assistance of the Applicants, for notifying the affected public. In addition, mop up procedures conducted by the OaF will be performed in a manner that minimizes site disturbances. As set forth in Table 8, the prescribed fire program is scheduled tot;>e initiated within MUs 10, 11, 12, 13, 14, and 15 approximately six (6) to eight (8) weeks following completion of mechanical treatment activities within these MUs. The recommended time lag between mechanical treatment and the prescribed fire allows for the drying of slash to provide additional fuel to the fire and to promote "hot spots" for recovery of open spaces. As discussed above, implementation of the mechanical and fire restoration activities in these MUs, which are located within the primary ITP impact area in Unit 17 of the Sebastian Highlands, serves to minimize the level of take resulting from authorization of the proposed action. Be advised that although Figure 7 shows MUs 10-1 5 as being currently occupied by scrub-jays, these areas are rarely used due to the poor quality of the scrub habitat. Each of the scrub-jay territories potentially affected by concurrent (or within a short time interval) burning the subject Unit 17 MUs include suitable habitat areas located outside of the subject MUs. These "off-site" habitat areas are sufficient to support the affected scrub-jay groups while targeted burned habitat areas are regenerating. It should be noted that the subject "off-site" areas are located within the Sebastian 92 I I I I I I I I I- I I I I I I I I I Ij Highlands Unit 17 ITP impact area. It is expected that habitat loss within the Unit 17 ITP impact area will occur incrementally, over a period of years, and not immediately. This situation emphasizes the importance of and validates the reasoning for immediately initiating restoration actions within the Unit 17 MUs, 10-15. Although not specifically addressed in Table 8, all marsh habitats embedded within the designated MUs shall be allowed to burn as part of the MU if appropriate hydrologic conditions exist within the wetland(s) to prevent the occurrence of muck fires. Freshwater depression marsh wetlands require frequent fire to limit invasion by woody shrub species, to maintain the integrity of the herbaceous community, and to reduce peat accumulation (Kushlan 1990). Therefore, the prescribed fire will serve to reduce shrub recruitment and to enhance the ecological integrity of this native matrix habitat type. The DOF will be responsible for determining the safety, from an ecological and urban interface standpoint, of burning the marsh communities. The primary objective of the restoration burning activities is to reestablish the structural attributes of the historical scrub landscape for purposes of optimizing habitat conditions for use by Florida scrub-jays and associated species of conservation concern. To achieve this objective, hot restoration burns will be applied to: 1.) consume small standing pines and slash left on the ground by mechanical treatments; 2.) initiate the creation of openings in the scrub by allowing small piles of slash to burn hot to promote exposure of patchy areas of mineral soils; and 3.) reduce height of standing shrub. For purposes of this HCP Management Program, and as set forth in Table 8, subsection Fire Intensity, the objectives of a "hot" restoration burn, which under this plan will be applied to management units that have been mechanically treated as described above, are defined as: a.) 100% consumption the lighter fuels (grasses, litter, twigs, and small stems (< 1 " diameter) - 1 and 10 hour timelag fuels); b.) best possible (75% to 95%) consumption of brush fuels (shrub 1" to ~" diameter - 1 00 hour timelag fuels); and c.) best possible consumption of the heavy fuels (stems> 3" diameter). Note: Most of the heavy fuels will be "pile-burned" in small, scattered piles to favor creation of open patches of mineral soils. Table 8 directs the restoration burning of three (3) MUs, 16, 17, and 18, at a fire intensity described as "mosaic". This burn structure is also referred to as "patchy". 93 1 1 1 1 1 1 1 1 1- , 1 1 1 I I ,j I 1 1 Ii 1 For purposes of this HCP Management Program, the objectives of a "mosaic" burn, which under this plan will be applied to the higher quality scrub and mesic flatwood habitat patches, are generally defined as: a.) 100% consumption the lighter fuels (grasses, litter, twigs, and small stems (< 1 " diameter) - 1 and 10 hour timelag fuels); b.) 50% to 75% consumption of brush fuels (shrub 1" to 3" diameter - 1 00 hour timelag fuels); and c.) best possible consumption of the heavy fuels (stems> 3" diameter). Note: Most of the heavy fuels will be "pile-burned" in small, scattered piles to favor creation of open patches of mineral soils. 5.3.2.3 MINIMIZATION MEASURES The following measures will be used in the field to reduce the potential for adverse impacts to natural community structure resulting from implementation of the recommended restoration treatments on the Scrub-Jay Habitat Compensation Areas. 1. Initiate habitat restoration treatments, mechanical and burning, within the Unit 17 conservation areas, Pelican Island Elementary School/Sebastian Highlands Scrub Conservation Area, to minimize the extent of take resulting from the proposed action. 2. Use of a logging contractor experienced in tree removal for purposes of habitat restoration. Strictly monitor soil disturbances resulting from logging action. 3. Use of existing jeep trails, historic fire breaks, and disturbed habitat areas as primary ingress and egress routes for removal of the harvested pine logs from each conservation site. Slash, twigs and small stems and branches (< 3" diameter), from logging operations will be primarily spread on-site to provide fuel to carry the prescribed fire. The larger slash, large stems and branches (> 3" diameter), will be collected into randomly scattered small piles to promote "hot spots" during the prescribed burn for purposes of exposing patchy areas of mineral soil. 4. Use of rubber tired heavy equipment for all mechanical treatment activities conducted on the site to minimize soil disturbance on the conservation sites. 5. Use of soft fire breaks, mowed lines in conjunction with foam or black lines, as control lines, wherever feasible. The use of plowlines in undisturbed habitat areas will be avoided if deemed safe by the OOF. If plowlines are needed, the. OOF will back-blade these areas following implementation of the initial burn. 94 ~- Ii I I I I I' I I I I I 1- ~ I I I I I I I 6. Performance of field surveys within occupied scrub-jay territories during the nesting season to locate active nests prior to the application of mechanical and/or prescribed fire treatment. Protection of the nest from any kind of management that may take place will be performed to prevent the take of scrub-jays as a result of implementation of habitat restoration and management actions. 5.3.3 Phase Two - Habitat Management Activities Upon completion of the initial restoration management actions on the Scrub-Jay Habitat Compensation Areas, prescribed fire will be the primary management tool applied to maintain optimal scrub-jay habitat quality. Future burning needs and the size and location of management units will be based on optimal Florida scrub-jay habitat structural criteria, as defined herein, and not fire frequencies due to the variation of natural community types to fire. The time between burns will also be dictated by the availability of fuels required to carry a fire. Long-term fire management activities shall promote the application of "mosaic" burns, as generally described above, to increase habitat heterogeneity across the scrub landscape. This will be accomplished by varying the size and location of future management units, fire intensities, and timing of fires (Robbins and Myers 1992; Breininger and Oddy 1998; Schmalzer et al. 1999). To the extent practical, no more than 33 % of the focal scrub oak habitat patches will be burned in anyone fire to insure that suitable cover, nesting sites, and foraging habitat for use by Florida scrub-jays are always available (Breininger et al. 1996b). The matrix flatwood habitats will generally be placed on a fire interval to burn at least once every three (3) years to maintain an open landscape. In order to restore optimal landscape conditions for scrub-jays and reduce hazardous fuel loadings, it is likely that one small fire will be needed at the North Sebastian Conservation Area and Wabasso Scrub Conservation Area on an annual basis. Future habitat management actions will be refined and improved based on feedback from monitoring the effects of the initial management actions, in conjunction with state-of-the science knowledge and habitat management resources. 5.3.4 Schedule for Imolementation of Habitat Restoration and Management Treatment Actions The proposed schedule for implementation of the initial mechanical treatments is provided in Table 7. All proposed mechanical treatments are scheduled for implementation and completion within one (1) year from the date of issuance of the Sebastian HCP ITP. The proposed schedule for implementation of the habitat restoration phase of the prescribed fire program is provided on Table 8. As noted on Table 8, restoration burns will be implemented at the Unit 17 Pelican Island Elementary School and Sebastian 95 I I I I I I I I I I I I I I I I I II I Highlands Scrub Conservation Area within six (6) to eight (8) weeks (or as soon as weather permits) of completion of mechanical treatment of these sites. A total of 292.8:t acres is targeted for burning during the first year of the HCP Management Program. The remainder, 353:t acres, is scheduled to be burned within two (2) to four (4) years from the date of issuance of the Sebastian HCP ITP. The proposed prescribed fire program is applied over the entire conservation sites to maximize open landscape conditions optimal for scrub-jays and to reduce hazardous fuel loadings within the conservation sites. It is also important to note that target conditions for restoration of suitable scrub-jay landscape conditions on the Sebastian Airport conservation properties are compatible and will improve and maintain operational safety conditions within this area of the airport. As discussed above, the prescribed fire rotation, season of burn, and design of future MUs, following completion of the initial restoration burns, will be based on feedback from the monitoring of the effects of the initial prescribed management actions in achieving the HCP Biological Objectives stated above with regard to optimal Florida scrub-jay habitat structure. General protocols for habitat assessment under this phase of the prescribed fire program are provided in Section 5.3.3. 5.4 Sebastian HCP Florida Scrub-Jay Habitat Management Monitoring Program (HCP Monitoring Program) The Applicants will initiate a monitoring program, for the term of the ITP, to ascertain the success of the HCP Management Program in progressing towards achievement of the stated HCP Biological Goals and Objectives. The purpose of the monitoring program will be to determine the distribution and status of the resident scrub-jay population and to evaluate the response of the scrub and mesic communities to applied mechanical and fire treatments. This information will be uS~,d to guide future management actions that serve to enhance demographic success of the study population. The habitat quality and demographic parameters to be measured under this monitoring program, as well as the schedule for implementation and reporting, are outlined below. As set forth below in 5.4. 1 . 1, each annual monitoring report will include a compliance monitoring section to demonstrate that the Applicants are progressing towards successful restoration of the scrub-jay habitat. This will be monitored in accordanc~ with the mechanical treatment and prescribed fire implementation directives and schedule set forth in Table 7 and Table 8 of the HCP Management Program. 96 1 1 1 1 1 1 1 I~ I~ ' 1 1 1- I~ I 1 1 1 1 I 5.4. 1 Monitorina Parameters 5.4.1.1 HABITAT QUALITY STUDIES 1 .

This section of the monitoring report will clearly outline actions to be completed for the next monitoring year. Each proposed action will be substantiated based on feedback 98 I I I I' I I I I I I II I- I I I I I I I from monitoring the effects of the initial management actions on habitat quality and scrub-jay habitat use. State-of-the science knowledge and habitat management resources will be integrated into future management strategies as needed. 5.4.1.2 FLORIDA SCRUB-JAY TERRITORY STUDIES 1 . Monitoring Objective: Quantify the number of scrub-jay territories and level of recruitment into restored habitat areas on the Scrub-Jay Habitat Compensation Areas. 2. Surv~y Methodology: Using the survey protocol set forth in Fitzpatrick et at. (1991), collect basic demographic data to obtain an estimated count of the total number of scrub-jay territories on-site, the number of individuals (adults and juvenal-plumaged) within each territory, and the approximate boundaries of each territory. Each Scrub-Jay Habitat Compensation Area will be surveyed for a minimum of three (3) consecutive days to delineate scrub- jay territories and to collect demographic data during appropriate times of the year. 3.

Monitoring Freauency: Habitat quality assessments shall be performed annually during the time period mid-February and March, with completion by March 30th of each monitoring year. 99 Demographic studies shall be performed twice annually, pre-nesting (mid- February and March) and post-fledging (July). 3. Reoorting Schedule: Once annually by May 15th of each monitoring year. Two (2) copies of the completed annual monitoring progress report shall be provided to the FWS Contact Office - Vero Beach, Florida. The first monitoring report will be due May 15, 2001, contingent upon issuance of the Sebastian HCP ITP. Reporting of the July 2000 (post-fledging) demographic data may be included in the May 2001 monitoring report, if collected for the 2000 nesting season. Reporting by May of each year allows for the land manager to make needed corrections to habitat management actions during the natural fire season. 5.5 Unforeseen/Extraordinary Circumstances "Unforeseen circumstances" or "extraordinary circumstances", as defined in the Endangered Species Habitat Conservation Planning Handbook (FWS and NMFS 1996), means "changes in circumstances surrounding an HCP that were not or could not be anticipated by HCP participants and the Service, that result in a substantial and adverse change in the status of a covered species". The Applicants and the FWS acknowledge that even with the detailed provisions set forth above in the Sebastian HCP operating conservation program for mitigating and minimizing impacts to the covered species, unforeseen circumstances may arise during the term of this HCP. Under the terms and conditions of this HCP the Applicants are committed to work with the FWS to address future unforeseen changes to the'!laximum extent reasonably practicable. In accordance with the Department of Interior's and Department of Commerce's "No Surprises" policy (50 C.F.R. Part ~ 17), the Applicants acknowledge that the FWS shall not require the Applicants to commit additional lands, additional funds, or additional restrictions on lands or other natural resources beyond the level of mitigation proposed under this Sebastian HCP, as long as the Applicants are adequately implementing the conservation actions of this Sebastian HCP, as set forth herein. Therefore, under the terms and conditions of this Sebastian HCP, the FWS and the Applicants agree that implementation qf additional mitigation measures to address unforeseen changes must be as close as possible to the terms of this HCP and must be limited to modifications in habitat management treatments and/or schedules within the Scrub-Jay Habitat Compensation Areas. The proposed HCP Monitoring Program will serve to provide the information linkage required to determine if an unforeseen change has occurred within the covered Florida scrub-jay population and to define reasonable and appropriate habitat management 100 measures, if any, that may be implemented within the Scrub-Jay Habitat Compensation Areas to reduce the adverse affects of these changes to the Florida scrub-jay. 5.6 Funding Three primary funding sources have been identified by Indian River County to support implementation of the proposed Sebastian HCP operating conservation program. The first source is the proceeds collected from timber sales proposed to be implemented on the Scrub-Jay Habitat Compensation Areas to initiate scrub-jay habitat restoration. A second, and primary funding source, are funds from the Indian River County Environmental Lands Acquisition bond program. These funds, in conjunction with proceeds collected from the timber sales, will be used to complete all mechanical treatments required to initiate restoration of optimal scrub-jay habitat conditions, as outlined in Section 5.3.2.1. These funds will also be used to support performance of restoration burning activities, e.g. establishment of fire breaks, as agreed upon by Indian River County and the OOF. Future management costs are expected to be minimal, limited to implementation of rotational prescribed fires by the Applicants and the OOF and the control of Brazilian pepper regrowth. The Environmental Lands Acquisition bond program and, a third funding source, the Indian River Mitigation Fund Account for upland and wetland restoration projects, will be used to support implementation of habitat management actions on the Scrub-Jay Habitat Compensation Areas, in the long term. The HCP Monitoring Program will be performed internally by the Indian River County Conservation Lands Manager and supporting staff. Therefore, the funding sources, as identified above, will be used by ,the Applicants to achieve stated Biological Goals and Objectives of the Sebastian HCP operating conservation program. 101 LITERATURE CITED ABRAHAMSON, W.G.1984.

Hodda 3:!21&-0912 February 7, 1995 Mr. Kenneth R. Macht, Chainnan Board of County Commissioners 1840 25th Street Vero Beach, FL 32960 Dear Me. Macht: In 1994, Indian River County voted to develop a Habitat Conservation Plan (HCP). Critical to the success of an HCP is preserving and maintaining as much of the remaining scrub in Indian River County as possible. Some of the most critical areas for protection are contained in approximately 155 platted lots in Unit 17 of the Sebastian Highlands. Until some protection is afforded these lots, all of the estimated 2,000 platted lots throughout the Sebastian Highlands will be subject to scrutiny under the Endangered Species Act for compliance with Section 9. At a recent Land Acquisition Commission (LAC) meeting, the LAC recommended the purchase of the 65-acre Sebastian Industrial Site scrub. While the U.S. Fish and Wildlife Service commends the County for proceeding with scrub habitat acquisition, we feel a bener use of these limited funds would be to acquire as many of the single family lots as quickly as possible. Acquisition of these lots would significantly improve the chance of implementing a successful HCP and would reduce the controversy surrounding Florida scrub. jay protection in Indian River County. Therefore, the Service recommends that a main core of approximately 120 scrub lots neighboring the protected Indian River County School Board scrub site at Pelican Island Elementary School, be highest priority for scrub acquisition during the HCP process. This would he.lp create support for the HCP and reduce listed species conflicts. The approved HCP and subsequent Section lO(a)(l)(B) pennit issuance woulqfacilitate the release of all remaining planed lots in the City of Sebastian. The successfully negotiated transfer of these . 120 lots in the HCP would virtually assure public support of the complete HCP. The Sebastian Industrial Site scrub is under no immediate threat of development, and any proposed impacts to scrub habitat on that site prior to completion of the County HCP would require and individual HCP. I I I I I I I I I~ I I' . , I., I, I" I I I I I I For these reasons the Service urges Indian River County, in the best interests of the County HCP, to immediately acquire the 120-Iot core scrub habitat adjacent to Pelican Island Elementary School. ~ David J.

I 1 I' I Sebastian Highlands Scrub Lots Page 2 I DESCRIPTION AND CONDITIONS I The subject Sebastian Highlands Scrub property was approved in early 1995 as a Flor'Ida Communities Trust (FCT) 50\ cost-share project. In 1995, the Sebastian Highlands Scrub project was ranked 14th out of 19 projects on the LAAC site acquisition list. The project is currently ranked 13th out of 15 sites. The City of Sebastian has expressed support of the overall project because the project will alleviate conflicts within the City concerning endangered species protection vs. private development rights. The initial overall Sebastian Highlands Scrub project consisted of .:180 lots. At a public hearing on July 16, 1996, the Board of County Commissioners approved the purchase of "Phase I" of the project by agreeing to buy 50 of 56 lots owned by Atlantic Gulf Communities (AGe). At that meeting, with acknowledgement.from the U.S. Fish and Wildlife Service (FWS), the B~ard eliminated from the overall project the northern group of 26 lots, which were determined by the FWS to be no longer crucial to the success of the project. In its application for state cost-share funding, the County chose to be the lead agency for pre-acquisition tasks and negotiations. During the past year, the county's acquisition consultant, in coordination wi th county staff, has conducted pre-acqulsi tion tasks and negotiations. Since the owners of the herein described lots within the project have accepted and executed purchase contracts, appraisal results for those lots have recently been released. -Advertised Public Meeting This public hearing has been advertised +30 days in advance to fulfill a State statute requirement that the County hold a public meeting after having provided at least 30 days advertised public notice to formally consider approving and exercising its purchase contracts for the Sebastian Highlands Scrub Phase II lots. The State requirement that the Board hold a public meeting to consider exercising its option after having provided 30 days advertised notice of the meeting applies because the County chose to keep its appraisal of the subject lots confidential until the sellers executed a binding contract. Once that contract had been signed, the appraisal was released and has been available to the public during the 30 day period prior to the' advertised public meeting. Besides meeting State statute requirements, the hearing on the subject lots will serve to meet a Land Acquisition Guide requirement that the County hold a public hearing prior to purchasing any property with land acquisition bond funds. I I I I I~ j I~ I, I. IJ 1- 1 -Site Characteristics I The subject 47 undeveloped lots consist of xeric oak scrub in Unit 17 of the Sebastian Highlands. All of these lots are located in the project core area in the vicinity of the Pelican Island Elementary School. . I These 47 lots, combined with 4 lots already owned by the City of Sebastian and 16 AGe lots being purchased near the school (totalling 67 lots out of 116 identified for acquisition in the school area), are an essential element of this core area. I I -Ownership Characteristics Currently, the subject 47 lots are owned by 41 individuals (see attached). The tax assessed value of each of these lots range from $6,600 to $11,830 depending on the size and accessibility of the lot. II I Sebastian Highlands Scrub Lots Page 3 I I -Acquisition Co.t-Share , Property Manaqement Two issues which are important to LAAC staff with respect to all proposed purchases are obtaining cost share assistance in property acquisition and addressing management cost.. I - Cost-Share I In 1994, Indian River County su~itted an application to the FCT, which was subsequently approved for 50\ cost-share funding, including 50\ of pre-acquisition expenditures (e.g., environmental audit, appraisals). - Utilities Water Line A..e....nt I I The Board of County Commissioners, at a public hearing on August 27, 1996, approved Phase I of the Utilities water line assessment project for the Sebastian Highlands. Of the 47 lots proposed herein for acquisition, 33 are subject to the Phase I Utilities asseSSment. The COmbined total of the assessment for the 33 affected lots is $52,658.96. On a per lot basis, the Utilities assessment averages !17\ of the appraised value. Although the signed purchase contracts indicate that each seller is responsible for providing clear title to their property, most of the contracts were signed by the sellers prior to notice of the Utilities assessaents, and those owners who have contacted staff have expressed dismay at the prospect of having to pay the assessments prior to closing. IC I~ I -. M&nageHnt Cos ts Management cost is always an issue with environmental lands acquisition. The FCT program, which is highly competitive state- wide, awards points for projects based on the provision of resource-based public access and use facilities. In order to qualify for FCT cost-share funding, the County obligated itself in its FCT application to provide limited access and resource-based facilities on the overall project property. Specifically, conditions of the Conceptual Approval Agreement include County provision of nature trails,., a picnic area, information kiosk, gazebo, and limited parking. Management of scrub habitat is also a described management plan condition for the project. "A number of initial site improvements, including fencing and resource management,. can be paid for with bond referendum funds as part of the property acquisition. I.provellients such as liaited parking will need to be funded by a source other than referendum monies. Potential funding sources include park development grants, county mitigation funds, and tree removal violation funds. . Ic I 1- I I I Relating to long term Ilanagement, the property will be incorporated into the countY-Wide park system and Danaged by the County Parks Division In coordination with county environ.ental planning staff. Volunteer groups will be asked to assIst the County with certain aspects of property management such as nature trail up-keep and Utter patrol. The County haa executed an interlocal agreement with the City of Sebastian regarding City aS8istance in policing the property. In all other respects, however, the County will be responsible for property aanagement. I I Ij 1 Sebastian Highlands Scrub Lots Page 4 1 1 county staff have opted to have a management plan for the project (see attached) drafted by the county's acquisition/lII4nagement consultants, an option which is specified in the County's contract with FloridAffinity, Inc. Page 25 of the draft plan summarizes estimated management and development costs of the overall Sebastian Highlands Scrub project. Please note that the draft plan for the total acqui8ition project vas previously reviewed by the Board when the Board reviewed the AGe lots purchase. Thi. plan i. in the proce.. of being lI04ified to account for the eliaination of the northern group of lot., and aay be subject to further change depending on the County'. success in negotiating purchases of additional Iota within the project. 1 1 1 -Appraisal In accordance with County Land Acquisition Guide and rCT procedures, an independent appraisal was obtained to determine an approved appraised value of the lots. Because the value of the individual lots did not exceed $500,000, only one appraisal was required to satisfy state and county procedural requirements. The appraisal firm selected was Armfield' Wagner. The appraisal was subsequently certified by a review appraiser (Boyle Appraisal Service), as required by the FCT. The appraised value for the combined 47 lots is summarized aa follows. 1 I--J 1- SEBASTIAN HIGHLANDS SCRUB - 47 LOTS 1 APPJtAISD VALID $396,900 , DIVBRl3II<3 MIA APP!lOYED APPR. 'nLOZ Armfield , Wagner $396,900 1- 1- The negotiated purchase price of $396,900 is 100' of the approved appraised value. Given the nature of the project and the fact that these appraised values reflect environmental permitting constraints, whereby in some cases the appraised value is less than tax assessed value, staff felt it was appropriate to make offers at the full appraised value. (The appraised value-s of the individual lots are summarized in an attachment to this memorandum.) 1 -Contract I In coming to terms with FCT and county staff on the negotiated purchase price (subject to County Commission and FCT approval), each seller has executed a standard FCT purchase contract with minor modifications. For ease of reference, rather than attaching each individual contract, attached is a copy of the contract that has been executed by each of the 41 sellers. I I .Pro1ect Plan To satisfy the FCT Conceptual Approval Agreement for cost-share funding, the County is required to submit a "project plan". In addition to an executed purchase agreement and approved management plan, a "project plan" includes: I Statement of total cost I I I Sebastian Highlands Scrub Lots Page 5 I Statement of award amount requested from FCT I Statement that the project plan is consistent with local comprehensive plan I Evidence that conditions imposed as part of the Conceptual Approval Agreement are satisfied Affidavit that there is no existing or pending violation of any local, state, regional or federal laws or regulations on the project site As confirmed by the Sebastian City Planner, the Sebastian Highlands Scrub lots purchase as proposed is consistent with the City's Comprehensive Plan. Documents of the project plan listed above _ aside from Board approval of the purchase agreeDent and ~gement plan - can be handled administratively, and have been provided to FCT by county staff contingent upon Board approval of the acquisition. 1 1 I' ANALYSIS .Water Line Assessments I~ 1- · Coordination' Compatibility of Projects Both the Utilities water line extension project and the Sebastian Highlands Scrub acquisition project are iaportant from an environmental standpoint, and are not incompatible. The water line project extends needed service to lots within the Sebastian Highlands as an improvement to residential potable water quality, and will ultimately promote the County's objective. of conserving ground water quality and quantity in the area. The scrub acquisition project will protect environmentally important habitat and primary aquifer recharge areas, as well as provide passive recreation, open space, and environmental education. I. : I~ County Planning Division and Utilities Department staff have coordinated on the two projects to determine how each project affects the other. Staff came to two main conclusions. The first was that, after review of the waterline project design, there is no opportunity to modify any water line segment within the scrub acquisition project, due to the need to service residences in the. area. The second conclusion was that the waterline assessments would affect lots within the scrub acquisition project, regardless of the timing of the assessment or scrub acquisition. · Alternatives 1- 1 1 There are a number of alternatives relating to the recent Utilities water line assessment, as it affects lots within the Sebastian Highlands Scrub acquisition project. One alternative is for the County not to proceed with the project acquisition. This alternative, however, would leave the lot owners to fend for themselves regarding payment of assessment fees on top of trying to obtain federal peI'1lllts to build in cOllpl1ance with the federal Endangered Species Act. Moreover, it would derail .ffort. to conserve environaentally important scrub habitat, and development of a Habitat Conservation Plan that the County is working in cooperation with the City of Sebastian. Another alternative is for the County to advise the sellers that they are obligated to pay the assessment as a condition of closing. However ~ since the assessment equals approxill4tely 17' of the appraised value, the sellers will likely balk and not sell to the County. 1 1 1 1- I . 1 Sebastian Highlands Scrub Lots Page 6 1 1 A third alternative is for the County to pay the assessments with bond funds as a cost of acquisition. Because the water line assessments were recently approved - as the Board is considering purchase of the Sebastian Highlands Scrub lots - the County has an opportunity to pay the assessments with bond funds as part of acquisition costs. If the Utilities assessment project occurred after the County had already purchased the lot., the County would still need to pay the assessment., but could not use bond funds because it would not be an acquisition cost. In such a scenario, the County would have to find another funding source, such as the general fund. It is staff's position that the most appropriate alternative is for the County to pay the water line assessments - for these ~d other lots acquired by the County within the scrub acquisition project - with bond funds, as an acquisition cost. If the County decides to pay the Utilities assessments, it is appropriate and equitable that the County extend assessment payment to other affected lots within the overall acquisition project, including 13 of the 50 AGe lots the County has approved to purchase as Phase Iof the project. The Utilities assessment for the 13 affected AGe lots totals $20,229.99. 1 1 1 1 I -Multiple Benefit. I~ - Environmental Education I; As with most of the County's proposed acquisitions, the Sebastian Highlands Scrub purchase will enhance education in the County. With this property, the educational function will consist of nature trails and educational displays for the site. Also, the Environmental Learning Center has expressed an interest in using the property as a "satellite" location for xeric scrub educational excursions. County staff will coordinate with the School Board, particularly with SChool Board staff at the Pelican Island Elementary School, concerning school use and access to the property. 1-1 I Comprehensive Plan Acquisition Co..i~ent Conservation Policy 6.2 of the County Comprehensive Plan commits the County to acquire a minimum of SO acres of xeric scrub for conservation purpo.... Although this minimua acreage has already been acquired, the Sebastian Highlands Scrub project contributes to this policy by conserving xeric oak scrub. The project also furthers obj.ctives in the City and County comprehensive plans relating to open space, aquifer primary recharge area protection, and rare species conservation. - I I 1 RECOMMENDATION: I Staff reco_ends that the Board of County C~ss1oner8 approve the purchase contracts for the 41 individual lots as Phase II of the Sebastian Highlands Scrub acquisition project. Staff also recOllllllends that the Board approve County payment, as a cost of land acquisition, of applicable Utilities water line assessments (including affected AGe lots) with bond funda. In addition, staff recoaaends that the Board approve exercise of the purchase contract., and authorize staff to proceed with closing on the lots, including submittal of a Project Plan Ulendment to the FCT to fulfill requirements of the FCT cost-share Conceptual Approval Agreement. 1 I I I Sebastian Highlands Scrub Lots Page 7 I I ATTACHMENTS: I oGeneral map of the lota oAppraiaed valuea of the 47 individual lote oSample Purcha..

Fish & Wildlife Service P.O. Box 2676 Vero Beach, FL 32961-2676 Re: Sebastian Highlands Scrub Lots Mitigation Alternative Dear Mike: I I am writing as a follow-up to our meeting on October 4, 1996, at which we discussed alternatives to mitigate development of +450 Sebastian Highlands scrub lots under the purview of the federal Endangered-Species Act, relating to the protection of Florida scrub jay habitat. I I Status of Sebastian Highlands Scrub Lots Acquisition I As you are aware, the Board of County Commissioners, at a public hearing on September 17, 1996, voted not to proceed with County/State acquisition of 49 individually owned scrub lots in Sebastian Highlands Unit 17. These lots were being considered as "Phase II" of a county scrub acquisition project or iginally cons.isting of +180 scrub lots in the vicinity of Pelican Island Elementary School. The Board's decision not to buy the Sebastian Highlands scrub lots was based largely on perceived difficulties of scrub management within an active residential subdivision. I. Although the Board's decision was specific to the 49 lots under consideration at the time, it is clear to county staff that the entire scrub lot acquisition project was affected by the decision. The County's option agreement to buy 50 Atlantic Gulf Communities (AGC) lots ("Phase I") has expJred, and AGC's representativp h~~ indicated that AGe is not willinQ to renew th~ option or SQ~ just ~A Qf tho ~O lots that are clustered northwest of P~lican Island El~m~ntary Conse entl, the County is not proceeding to bu an scrub lots in Sebastian High1an s. \. . ~> A&,C. c..M"jut its Mh'Pl Q.~te.'" tl\IS (.cttv- ~~ wr\tt"oU\. ..:. -eo ~...,( "p.y,,- Although the Board is not proceeding with the scrub lots purchase, it recently approved the purchase of two relatively large tracts in north Sebastian: the +76 acre "AGC Industrial Tract," and the +312 acre "St. Sebastian PUD" property. These two contiguous tracts, located east of the Sebastian Municipal Airport and golf course; contain approximately +40 acres of occupied scrub jay territory as well as =50 acres of overgrown xeric oak and sand pine scrub with potential for scrub jay habitat restoration. North Sebastian Conservation Area I. I. I I I The City of Sebastian has requested that the County allow for a potential future extension of Gibson Street through the North Sebastian Conservation Area in existing and future right-Of-way (ROW). Assuming that this 'road would be I 1 I I .- 1 1 1 1 I 1 1 1 I. I. I.; I, I,' 1 1 1 I I I constructed in the alignment of the existing ROW, it is estimated that +3 acres of scrub jay habitat would be impacted by the road project. Wabasso Scrub Addition Within the next few months, the County Land Acquisition Advisory Committee (LAAC) will be considering the purchase of a northern addition to the 111 acre Wabasso Scrub Conservation Area that was bought by the County in October, 1995. This northern addition has been proposed by the owner of Park Place, the development in which the property is located, and consists of approximately 5 acres of xeric oak scrub habitat (within 1/2 mile of the Sebastian Highlands Unit 17 scrub lots) . If the County proceeds to buy this addition, it will expand the +25 acres of occupied scrub jay territory and +32 acres of unoccupied habitat being restored in the existing Wabasso Scrub Conservation Area. Mitigation Proposal County staff is requesting that the u.S. Fish and Wildlife Service (FWS) consider the following proposal to serve as mitigation for the planned Gibson Street extension and for release of the +450 privately owned 1/4 acre scrub lots in the Sebastian Highlands that have been identified by the FWS to be scrub jay habitat: . County purchase and management of +40 acres of occupied scrub jay habitat and restoration of +50 acres of scrub on the St. Sebastian PUD and AGe -Industrial Tract properties ("North Sebastian Conservation Area"). . County purchase and management of +5 acres of scrub at the south end of Park Place Development, as an addition to the +57 acres of scrub habitat now under County management in the Wabasso Scrub Conservation Area. If this proposal is generally acceptable to the FWS, county staff will schedule an item before the Board of County Commissioners for authorization to proceed with drafting a Habitat Conservation Plan (HCP) based on the proposed mitigation. I look forward to. your response. If you have any questions or wish to discuss this matter, please contact me at 567-8000, ext 258. ~&c- Roland M.

BOX 2676 VERO BEACH, FLORIDA 32961.2676 November 12. 1996 Mr. Roland DeBlois Indian River County Environmental Planning and Code Enforcement Section 1840 25th Street Vera Beach, FL 32960 Dear l\.1r. DeBlois Thank you for your October 17, 1996 letter regarding Indian River County's alternative Florida scrub jay (Aphelocoma coerulesce~ coerulescens) mitigation proposal that addresses adverse affects anticipated from continued housing construction in Sebastian Highlands. The Fish and Wildlife Service (FWS) has considered your proposal in context with scrub jay population data for northern Indian River County, conservation strategies attempted previously, and recent discussions my staff and the County have had regarding the failure of Indian River County to pursue scrub acquisitions in Sebastian Highlands. Before we discuss your current proposal, we would like to review previous efforts to resolve the controversy surrounding habitat alterations in Sebastian Highlands and conservation of scrub jays. After reviewing the rather lengthy tile associated with this project, we understand that in the late 1980s the Florida Game and Fresh Water Fish Commission (GFC) eXl'ressed concern over housing construction impacts on Sebastian's scrub jay populations. Beginning in 1991, the FWS and GFC began consulting with the City of Sebastian regarding scrub jay conservation. By the time an exhaustive scrub jay survey had been completed in 1991,35 families were known to occur within the city limits of Sebastian. A general lack of enforcement and willingness to implement conservation strategies led to a decline in the number of scrub jay families, such that, by 1993 only 27 rem~ined in Sebastian. By June 1992. both the FWS and City agreed that development and implementation of a habitat. conservation plan (-conservation plan) and the issuance of an incidental take permitfor scrub jays ':Vas'the only ~bl~ option that would provide for continued housing construction and scrub jay . . '". ..... ~ cdO$er:vation. Unfor:tlinately, continuing delays in conservation plan development have resulted 'in de~lines in scrub jays. As of early 1996, only 20 families existed in and around Sebastian. D~ng ~e..frve years we h~ve contempl~ted the fate of scrub jays and lot owners in ~ebastian Highland's; we have lost 15 scrub jay families or 43 percent of the population in northern Indian River County. '.. ~ ...,.....: . '--/::-Q.i'.'~~~- .:o~'~TI.,r. ....::':'..-c- .000"l.....,c.,"'ICf"'.."l''V'.. I I I I I I I I I I l- Ie I I I I I I- I While considering your current proposal, we often referenced the outline for the County-wide conservation plan and it's more recent. but short lived predecessor, the site specific Sebastian Highlands conservation plan. Though different in scope. both conservation plans were intended to relieve the County and Sebastian Highland lot owners of their responsibilities to avoid take of the threatened scrub jay, by providing '"mitigation:' Mitigation in both conservation plans included conservation and management of scrub oak habitat. Unfortunately, it has never been clear which conserved and managed lands were being proposed for mitigation in either of the two conservation plans. However. there seems to have been a general consensus among the FWS and County that acquisition of the St. Sebastian PUD, AGC Industrial Tract, Wabasso Scrub, and Sebastian Highlands Unit 17 lots would provide a substantial portion of the mitigation that would ultimately be needed during development of a County-wide conservation plan. Your current proposal now requests FWS approval of a mitigation strategy that does not include lots in Unit 17 of Sebastian Highlands. For comparative purposes, we have summarized the approximate acreages of scrub jay habitat (and families) adversely affected and protected under the previous conservation plans and the current mitigation proposal. · Previous Conservation Plan Proposed Adverse Affects = Alteration of 216 scrub lots in Units 3, 5, 10, and 17 in Sebastian Highlands or about 47 acres of scrub jay habitat. Four families of jays are known to currently reside within these Units. A total of 47 acres and four scrub jay families would be affected. Proposed Miti~ation = 119 lots in Unit 17 (about 30 acres) plus about 20 acres of managed school board property. Contiguous tracts known as the St. Sebastian PUD and AGe Industrial Tract contain about 40 acres of occupied habitat and about 50 acres of unoccupied scrub habitat. The remaining uncommitted occupied and unoccupied habitat ",ithin the Wabasso Scrub Conservation Area (about 25 acres). Management plans were also proposed for other public lands containing scrub jays, including the Sebastian golf course, airport, and Sebastian elementary school. At total of sixteen families of jays reside in these areas. A total of 115 acres of occupied habitat. 50 acres of Unoccupied habitat. and 16 scrub Jay tamilies wouid benetit from this proposal. · The Current Mitigation Proposal Proposed Adverse Affects = Alteration of 185 scrub lots in Units 3, 5, and 10 in Sebastian Highlands (about 47 acres), development of 148 lots in Unit 17 (about 37 acres), road construction impacts to about 3 acres of occupied scrub habitat. Eight families reside in these areas. About 87 acres of occupied habitat and eight scrub jay families would be affected by this proposal. 2 I I I I I I I I, Ie' I I, 1- j I I I I, I I I Proposed Miti~ation = Contiguous tracts known as the St. Sebastian PUD and AGC Industrial Tract contain about 40 acres of occupied habitat and about 50 acres of unoccupied scrub habitat. The remaining uncommitted occupied and unoccupied habitat within the Wabasso Scrub Conservation Area (about 25 acres). An additional 5 acres of scrub (presumably unoccupied) is proposed to be acquired and added to the Wabasso Scrub tract. Five families are known to occupy these lands. About 80 acres of occupied habitat and 50 acres of unoccupied habitat, and five scrub jay families would be protected under this proposal. By comparison. implementation of the previous conservation plan would have resulted in alteration of about 47 acres of habitat while 115 acres of occupied habitat would have been conserved and managed. Only four additional families would have been lost while 16 would have been protected. The County's current mitigation proposal would adversely affect 84 acres and protect and manage about 80 acres. <':;even famili.es w(:~ld be lost while only five families would be protected. Though neither plan provides extreme benefits to scrub habitat beyond that currently available, . the proposed mitigation plan results in substantial additional losses of scrub habitat and scrub jays. Based on these estimates, the current mitigation proposal provides long-term protection for only five scrub jay families as well as for those families that may eventually occupy publicly held scrub that is currently overgrown and unoccupied. In short, the current proposal could result in an additional loss of 65 percent of the remaining scrub jays in northern Indian River County. Added to losses since 1991, the proposal and past adverse affects would result in an 80 percent loss of scrub jays. On October 4. 1996 FWS staff met with you to discuss ramifications of the County's recent decision to terminate acquisition of scrub habitat in Sebastian Highlands. According to our meeting notes. it was suggested that the County pursue any and all possible acquisition and management options available to offset the additional adverse affects that housing construction in Unit 17 will have on Florida scrub jays. Although your letter indicates the Coiintywill not pursue the 34 AGC lots in Unit 17, subsequent conversations with you suggest acquisition may still be sought. We support this effort and believe the 34 AGe lots, in combination with Pelican Elementary School scrub, may provide enough suitahle habitat to minimize the adverse affects of habitat fragmentadon aue to losses 111 the remainder of Unit 17. These scrub parcels, if properly managed, may be essential "stepping stones" for the dispersal of scrub jays from and to northern Indian River County. After reviewing the County's current proposal, we found that acquisition of five acres of scrub has been added to the mitigation measures proposed during development of earlier conservation plans. Other possible actions that could benefit scrub jays, but were not addressed in the current proposal include: · Development of individual scrub management plans for the airport, Sebastian golf course, 3 1 I I I I I I 1 I I- I, 1- 1-, I- I I I I I and Sebastian and Pelican Island elementary schools, including perpetual conservation easements where appropriate. · Cooperatively develop scrub management plan for recently purchased State lands in Indian River County. · Identification of additional scrub habitat within the airport property that could ,be conserved and managed for scrub jays. · Acquire the 34 AGC lots and develop a scrub management plan for this area. · Cost-sharing with the state to conserve and manage other scrub parcels in the County. In summary, we believe the County's proposal falls short of providing adequate protection and management of scrub habitat in northern Indian River County. We do not believe the County has outlined all measures that have previously been suggested or explored all other possible scrub conservation alternatives. Therefore, as proposed, the current mitigation plan would not provide components essential for the development of an acceptable conservation plan. If you would like to discuss revisions to the County's proposal and any alternative mitigation strategies that may be appropriate please contact Mike Jennings at 562-3909.

Please note that they were compiled during short visits and are therefore somewhat incomplete. We were fortunate to see a bald eagle at the Sebastian PUD/ AGC Industrial Tract Scrub. Unfortunately, no P. smallii was found in Indian River County, although we did find it S1. Lucie County. We do believe that it could be found that far north so keep an eye out for it. To distinguish it from P. nana you must use seed size. The seeds of P. smallii are 1.2 - 1.4 mm long while those of P. nana are 0.6- 0.8 mm long.
