The Reserve includes the Rookery Bay Colony, which are two small keys designated by theFlorida Fish and Wildlife Conservation Commission as a Critical Wildlife Area. Briggs Nature Centeris part of the Research Reserve. The Reserve receives an estimated 10,000 recreationists annually.OWNERSHIP: Florida Office of Coastal and Aquatic Managed Areas; parts are co-managed with the U.S.Fish and Wildlife Service. Briggs Nature Center is run by The Conservancy.HABITATS: *slash pine flatwoods, *temperate hammock, *mangrove forest 36,030 acres; 14,412 ha),*tidal marsh, *estuarine, *open water, tropical hammock, xeric oak scrub, cypress swamp, freshwatermarsh, cattail marsh, sawgrass marsh, riverine, lacustrine, coastal strand, seagrass bedsLAND USE: *conservation, recreation, environmental educationIBA CATEGORIES: significant populations of Threatened and FCREPA species; significant numbers ofwading birds and larids; significant natural habitats; long-term researchAVIAN DATA: the Reserve supports significant populations of wading birds, shorebirds, and larids(especially at Cape Romano), and probably support upland species such as Mangrove Cuckoos,Black-whiskered Vireos, and “Florida” Prairie Warblers (e.g., see the Ten Thousand Islands NationalWildlife Refuge IBA, pages 250–251). A small patch of xeric oak scrub that was never known to beoccupied naturally by Florida Scrub-Jays has served as a translocation experiment since 1989. Thispopulation, which numbers two pairs, has required additional transplanted birds from ArchboldBiological Station to be maintained.
