Long Distance Migrations, Landscape Use, and Vulnerability to Prescribed Fire of the Gopher Frog (Lithobates capito)

Abstract

Abstract The Gopher Frog, Lithobates capito, is an endemic to upland, fire-maintained pine forests on the Southeastern Coastal Plain and requires open, isolated wetlands for breeding. This species has experienced drastic population declines because of habitat loss and degradation and now occurs only in scattered populations in the southern United States. We tracked the post-breeding movements and burrow use of 17 Gopher Frogs in the Sandhills of North Carolina using radio telemetry. Nine frogs were successfully tracked to summer refugia; the other eight frogs shed their transmitters or were killed by predators or fire during migration. Frogs traveled 0.5−3.5 km (mean = 1.3 km) between the breeding pond and a summer refugium. The 3.5-km movement is substantially longer than has been reported for Gopher Frogs before. Our results suggest that an area of 3,739 ha (9,239 acres) around breeding ponds is required to provide summer habitat for Gopher Frogs. Eight of nine frogs used holes associated with the stump...
