NatureServe Global Conservation Status Factors

Range Extent: 20,000-2,500,000 square km (about 8000-1,000,000 square miles)
Range Extent Comments: Range encompasses southern Ohio, southwestern West Virginia, much of Kentucky, western Virginia, and central and eastern Tennessee (Barbour 1971, Green and Pauley 1987, Conant and Collins 1991, Redmond and Scott 1996, Minton 2001). Elevational range extends to at least 477 meters in the Great Smoky Mountains National Park (Redmond and Scott 1996).

Number of Occurrences: 81 - 300
Number of Occurrences Comments: This species is represented by a large number of occurrences (subpopulations).

Population Size: 10,000 - 1,000,000 individuals
Population Size Comments: Total adult population size is unknown but presumably exceeds 10,000. This salamander is secretive and not readily found in large numbers, and it is not consistently obtained in sites where it has been previously recorded. In Kentucky, the species seems to be nowhere abundant, but it is "probably as common in the Inner Blue Grass as anywhere" (Barbour 1971).

Overall Threat Impact: Low
Overall Threat Impact Comments: No major threats have been identified.

Short-term Trend: Relatively Stable (<=10% change)
Short-term Trend Comments: Current trend is not documented, but the population probably is relatively stable overall.

Long-term Trend: Decline of <30% to increase of 25%
Long-term Trend Comments: Over the long term, extent of occurrence likely has been relatively stable; population size, area of occurrence, and number/condition of occurrences probably have declined by less than 25%.

Ecology & Life History
Help
Non-Migrant: N
Locally Migrant: N
Long Distance Migrant: N
Riverine Habitat(s): SPRING/SPRING BROOK
Palustrine Habitat(s): Riparian
Special Habitat Factors: Benthic, Burrowing in or using soil, Fallen log/debris
Habitat Comments: Habitat includes muddy and silt-laden areas, where it is most often found under logs or stones along shallow, sluggish streams, spring runs, floodplains, or seepage areas, usually but not always in wooded areas (Barbour 1971, Redmond and Scott 1996). Sometimes this salamander occurs in roadside ditches and other wet areas far from water (Barbour 1971), and may cross roads in larges numbers during wet weather (Green and Pauly 1987). Egg-deposition sites include the undersides of dead leaves in quiet pools (Green and Pauley 1987).
