Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor/s: Geoffrey Hammerson
Reviewer/s: Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Least Concern in view of its relatively wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It can be found in the vicinity of moist rocky crevices in ravines, canyons, rubble, seepages, caves, and wooded slopes. It is mostly found under rocks, logs, or leaves during day. It is a terrestrial breeder with direct development.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): urbanization and conversion of forest into cropland have eliminated many populations, but the species remains common in suitable habitat (Petranka 1998). Most of the habitat loss was not recent. It is probably now stable and not seriously threatened.

Conservation Actions [top]

Conservation Actions: Habitat protection and population monitoring needed. It occurs in several protected areas, including the Great Smoky Mountains National Park.
