(Additional lands have been targeted for purchase in Pasco County, but acquisition in thisarea has not yet begun). This IBA is essential to sustain a population of black bears in coastal westcentralFlorida; the bears are monitored via radio telemetry. Vehicle mortality continues to threatenthe long-term survival of this population. Chassahowitzka National Wildlife Refuge: _____ •Weekiwachee Preserve protects four miles (6.4 km) of frontage along the southern shore of theWeekiwachee River, which is used regularly by Florida manatees. • The Preserve supports at least 68species of butterflies, 14 species of listed plants, and 7 non-avian vertebrates. • Severalarchaeological sites are known.THREATS: Chassahowitzka National Wildlife Refuge: _____. Weekiwachee Preserve: offsitedevelopment, human disturbance, exotic plantsCONSERVATION ISSUES: Chassahowitzka National Wildlife Refuge: _____. Weekiwachee Preserve:A management plan (Kelly et al. 1997) has been prepared. The Preserve is designated as “urbanfringe parkland,” and management for public recreation will be balanced with protection of wildlifesuch as black bears. About 560 acres (224 ha) of the property consist of disturbed areas surrounding500 acres (200 ha) of pits from which limerock was extracted. These pits are 40–60 feet (12–18 m)deep, have a limited shoreline, and are relatively sterile. Future recreational use of the Preserve willbe centered around this area to minimize disturbance to native habitats. However, about 200 acres (80ha) of the disturbed area is used by breeding Wilson's Plovers and Least Terns. This area is adesignated Research Area and is off-limits to the public at all times. • Frontage along theWeekiwachee River will be managed as a Special Protection Area where development will beprohibited, and to which access will be solely on foot. • About 18% of the Preserve consists of fire-
