The Important Bird Areas of Florida: 2000–2002 – Pranty – 2-Jul-02 125Florida Scrub-Jay 1992–1993 400 groups 15% (R)Overall diversity undated list – 1982? 313 natives Additional species from observations in4 exoticsFlorida Field NaturalistScaup data from +Herring and Collazo (2001), eagle GIS coverage provided by Julia Dodge (Florida Fish andWildlife Conservation Commission), shorebird data from +Sprandel et al. (1997), scrub-jay data from +Pranty(1996b), other data provided by Gary Popotnik (U.S. Fish and Wildlife Service). Also see +Breininger (1997).OTHER RESOURCES: Canaveral National Seashore contains a mix of temperate and tropical habitats;Turtle Mound is the northernmost location for many tropical species. The Seashore includes 24 miles(38 km) of undeveloped beaches and dunes, the longest stretch of undeveloped coastal strandremaining along Florida's Atlantic coast. Over 4000 sea turtles nest on the beach annually. Over 100archaeological sites are known, including many on the National Register. • Cape Canaveral AirStation contains a large population of the ♦“Southeastern” beach mouse (Peromyscus polionotusniveiventris), a Federally Threatened species. There also are a number of aboriginal and recentarchaeological sites. The name “Canaveral,” referring to the easternmost point on the Cape, wasnamed by ____ in ____ and is one of the first-named landmarks in North America. (The site wasrenamed Cape Kennedy for several years after President Kennedy's assassination, but reverted back toCape Canaveral for historical reasons). • In addition to 317 species of birds, Merritt Island NationalWildlife Refuge contains over 1000 plant species [all native?], 80 fishes, 53 reptiles (including 3exotics), 32 mammals (5 exotics), and 19 amphibians (1 exotic). • Together, the Refuge and Seashoresupport 14 Federally listed animals.THREATS: *human disturbance, *exotic plants, *habitat succession, *feral hogs, developmentCONSERVATION ISSUES: Canaveral National Seashore: Long-term fire suppression has resulted inheavily overgrown scrub habitat, and Florida Scrub-Jay populations have declined severely.Management currently includes mechanical treatment of scrub and prescribed fire. • Exotic plants,primarily Brazilian pepper and Australian-pine, are serious threats. Seashore staff is working with thestate and county to remove exotic vegetation. • Impoundment of the salt marshes for mosquito controlhas extensively altered the habitat. Many of these impounded marshes are being reconnected to theMosquito Lagoon. • Cape Canaveral Air Station: A long history of fire exclusion has resulted inoak scrub on the Station becoming extremely overgrown, which threatens the continued survival ofFlorida Scrub-Jays onsite. Extensive habitat disturbance and fragmentation has occurred fromdevelopment of launch facilities. Station personnel are conducting a moderate amount of scrubrestoration, using mechanical means and controlled burning, but the effort is on too small a scale toallow the scrub-jay population to recover. The Station also has a large volume of traffic on manyroads, which may be further impacting scrub-jay populations. • There is great potential for theinvasion of exotic plants into several areas. • Merritt Island National Wildlife Refuge: Long-termfire exclusion has resulted in heavily overgrown scrub habitat, and Florida Scrub-Jay populationshave declined severely. Management for scrub-jays needs to be increased and accelerated, as numbersare declining from habitat succession. In the early 1990s, 500 groups of scrub-jays were estimated tooccur—less than half that could occur with additional habitat management—and this number hasbeen further reduced in recent years. Management currently includes mechanical treatment of scruband prescribed fire. • Invasive exotic plants (Brazilian pepper and Australian-pine) are a seriousthreat, and are chemically and mechanically controlled. • Extensive alteration of the salt marshes formosquito control has extensively altered the habitat by ditching and impounding, and helped to causethe extinction of the “Dusky” Seaside Sparrow. Currently, many of these impounded marshes arebeing reconnected to the Mosquito Lagoon. • Trappers remove 3000 feral hogs per year. • For otherinformation on the “Dusky” Seaside Sparrows, and the actions and inactions that drove it toextinction, see +(Sharp 1970), +(Delany et al. 1981), +(Walters 1992), and +Kale (1996).
