HABITAT DESCRIPTION: |
|
The range of this species is entirely contained within the southern Appalachian mountain region of Tennessee, North Carolina and Virginia (Martof et al. 1980). Most abundant in spruce-fir forest, but also found (at lesser abundance) in mesophytic cove hardwoods (Huheey and Stupka 1967, Petranka 1998). Adults occupy the forest floor sometimes well
away from surface water. Utilize moss, leaf litter, rotten logs, bark of stumps and logs, and rocks for shelter (Martof et al. 1980). NATURE SERVE GLOBAL HABITAT COMMENTS: Chiefly spruce-fir forests, also (in lower abundance) hardwood forests at lower elevations. Hides under moss, leaf litter, logs, bark on stumps, and rocks. Ascends trees to
about 2 m in wet or foggy weather. Spends winter in underground seepages. Eggs are laid in underground cavities among rocks of spring seeps.
