About Big Levels salamander
Big Levels Salamander (Plethodon sherando)
The Big Levels salamander (Plethodon sherando) is a species of salamander found exclusively in Virginia, within the eastern United States. Its common name refers to the Big Levels region in southeastern Augusta County, Virginia, an area characterized by flat to gently rolling mountain tops in the Blue Ridge Mountains where the species was discovered. The specific epithet, 'sherando,' is derived from Sherando Lake, also located in the George Washington National Forest.
Description and Habitat
This salamander belongs to the genus Plethodon and is part of the Plethodon cinereus group. Physically, it bears resemblance to P. cinereus and P. serratus, particularly in its coloring. The Big Levels salamander possesses a greater quantity of white pigment on its underside than gray. Its back typically displays red and gray coloration, which may include stripes or spots. Distinctive features include legs that are longer and a head that is slightly wider when compared to P. cinereus. The holotype, an adult male, measured 95 mm (3.7 inches) in total length and 42 mm (1.7 inches) from snout to vent.
The preferred habitats for the Big Levels salamander include temperate forests and rocky environments. At the edges of its range, it has been observed co-occurring with Plethodon cinereus at lower elevations. However, at higher elevations, it is the sole species of small Plethodon. Studies have indicated that P. sherando and P. cinereus occupy distinct microhabitats; P. sherando tends to inhabit areas with warmer air temperatures but cooler substrate temperatures, while P. cinereus is found in environments with higher relative humidity and cooler air temperatures.
Conservation Status
The Big Levels salamander is currently listed as Vulnerable on the IUCN Red List. This designation is primarily attributed to its limited geographic distribution. While detailed information on conservation status and specific threats is scarce, potential risks include ecosystem degradation resulting from logging activities.
