Scrub Habitat — Tampa, Florida

Florida scrub is one of the rarest and most biologically distinct terrestrial ecosystems in North America, occurring almost exclusively on ancient marine sand ridges that were once islands or coastal dunes during periods of higher sea level. In the Tampa region, these elevated sandy terraces historically supported a mosaic of scrub, scrubby flatwoods, and sandhill communities across Hillsborough County. As documented in the Hillsborough County government's conservation program materials, much of this upland habitat has been converted to urban and suburban land use over the twentieth century, leaving the remaining intact patches ecologically isolated and under active management pressure.

Within the city of Tampa itself, scrub habitat is largely fragmented by development. The county-scale conservation response — centered on the Jan K. Platt Environmental Lands Acquisition and Protection Program (ELAPP) — has worked since 1987 to acquire and manage the most significant remaining parcels, many of them located south and east of the urban core. The Department of Conservation & Environmental Lands Management, operating under the Hillsborough County Board of County Commissioners, administers day-to-day stewardship of these lands, including prescribed burning and habitat restoration programs that scrub communities require to persist.

Hillsborough County's Jan K. Platt Environmental Lands Acquisition and Protection Program originated with a 1987 voter referendum, as documented by the ELAPP Collection at the University of South Florida Digital Commons. The program was initially funded through a $21 million ordinance and a $100 million bond authorization, and has been reauthorized by Hillsborough County voters twice since — in 1990 and again in 2008. In 2014, the program was renamed in honor of Jan K. Platt, a longtime county commissioner associated with its creation.

As of the program's current documentation on the Hillsborough County government website, ELAPP manages more than 63,400 acres of environmentally sensitive wildlife habitat and corridors across Hillsborough County. The USF Digital Commons records protection of over 61,000 acres of rare and important habitat, achieved through partnerships with state-funded programs including Preservation 2000 and Florida Forever. Scrub and scrubby flatwoods habitats rank among the priority community types acquired under the program, given their rarity and the degree to which development has reduced their extent throughout the Tampa Bay region.

The program operates with a citizen-based advisory structure and coordinates land acquisition across multiple ownerships, including the Florida Department of Environmental Protection, which holds significant acreage at jointly managed preserves. Passive recreational uses — hiking and wildlife observation — are permitted at multiple ELAPP lands, particularly at scrub preserves located south and east of the urban core, according to Hillsborough County government documentation.

Balm Boyette Scrub Preserve is the largest and most ecologically significant scrub preserve in Hillsborough County. As reported by the Observer News in June 2025, the preserve encompasses approximately 4,870 combined acres: 3,595 acres owned by the Florida Department of Environmental Protection and 1,275 acres owned by Hillsborough County. Land acquisition at Balm Boyette occurred between 1992 and 2005. The preserve contains 11 distinct habitat types and, according to the county's management plan, holds some of the largest intact and contiguous patches of scrub and scrubby flatwoods remaining anywhere in Hillsborough County. The Observer News account from June 2025 also documents that urbanization of surrounding areas and the historical suppression of natural fire cycles present ongoing management challenges at the site.

Alafia Scrub Nature Preserve is an 80-acre ELAPP-acquired parcel located along the Alafia River corridor. According to the Hillsborough County government, the preserve was purchased in 1998 using ELAPP funds supplemented by Florida Communities Trust assistance. Its habitat mosaic includes hammock, scrub, creeks, ravines, shoreline, and tidal marsh — a combination that reflects the interface between upland scrub communities and the river's lowland and estuarine environments.

Moody Branch Wildlife and Environmental Area is another ELAPP-managed site documented in connection with scrub-jay monitoring activity. In January 2025, a Florida scrub-jay was banded at Moody Branch, located approximately 10 miles from Balm Boyette, according to Tampa Audubon. The site's appearance in scrub-jay documentation confirms its role in the broader network of ELAPP lands managing scrub communities across the county.

Florida scrub occupies well-drained, nutrient-poor sand substrates that support a distinctive assemblage of drought-tolerant, fire-adapted plants. The habitat is characterized by sand pine (Pinus clausa), scrub oaks including Quercus inopina, Quercus geminata, and Quercus myrtifolia, and Florida rosemary (Ceratiola ericoides), along with numerous endemic understory plants. These communities depend on periodic fire to prevent canopy closure by taller vegetation, which shades out the open, sunny conditions scrub plants and animals require. As documented in the county's ELAPP program materials, prescribed burning is a central management tool used to maintain scrub and scrubby flatwoods at preserved sites across Hillsborough County.

The Florida scrub-jay (Aphelocoma coerulescens) is the habitat's most recognized indicator species and the only bird species found exclusively in Florida. The Florida Fish and Wildlife Conservation Commission documents that the Florida scrub-jay has declined by approximately 90% over the past century, with habitat fragmentation and fire suppression identified as the primary drivers. The species holds federal Threatened status under the Endangered Species Act. Scrub-jays require low, open scrub with sandy patches for caching acorns, and the FWC identifies prescribed burning as the most critical tool for maintaining suitable habitat structure.

The suppression of natural fire in landscapes surrounded by urban development — the condition that characterizes most of the remaining scrub in Hillsborough County — accelerates the transition of open scrub to closed-canopy conditions that no longer support scrub-jay territories or the endemic plant species associated with early successional scrub.

In December 2024, a Florida scrub-jay was documented at Balm Boyette Scrub Preserve — the first recorded sighting there in more than 20 years, according to Tampa Audubon. The same bird was subsequently banded in January 2025 at the Moody Branch Wildlife and Environmental Area, approximately 10 miles from Balm Boyette. Tampa Audubon reported the sighting in connection with ELAPP's ongoing work to manage scrub habitat specifically for scrub-jay recovery across its preserve network.

The Observer News reported in June 2025 that Hillsborough County is advancing a management plan aimed at keeping Balm Boyette Scrub Preserve ecologically functional over the long term. The plan addresses the dual pressures of increasing urbanization in the surrounding landscape — which limits the natural movement of fire and wildlife — and the logistical complexity of executing prescribed burns adjacent to residential areas. The preserve's 11 habitat types and status as one of the county's largest intact scrub landscapes make it a focus of sustained management attention.

Tampa Audubon engages citizen science programs that include monitoring of scrub habitat across ELAPP lands, complementing the county's institutional management with community-based observation and documentation.

Hillsborough County's ELAPP preserves, including Balm Boyette Scrub Preserve and Alafia Scrub Nature Preserve, are documented as open to passive recreational uses including hiking and wildlife observation, according to Hillsborough County government. These uses are oriented toward low-impact interaction with the preserved landscapes rather than developed recreational infrastructure.

Tampa Audubon, an active chapter of the National Audubon Society, provides a civic pathway for residents to participate in habitat monitoring and documentation at ELAPP scrub lands. The organization's citizen science programs generate observational data that contributes to the county's understanding of species presence and habitat condition at managed sites.

The ELAPP program itself operates with a citizen-based advisory structure, as noted in Hillsborough County's program documentation, situating public participation at the governance level — not only in field activities. The county's Department of Conservation & Environmental Lands Management is the primary institutional contact for questions about land management practices, prescribed burn schedules, and preserve access at ELAPP sites. The Hillsborough County Board of County Commissioners retains oversight authority over the program and its conservation priorities.
