HABITAT DESCRIPTION: |
|
Coastal plain habitat includes Coastal Plain flatwoods dominated by loblolly or longleaf pines and wiregrass (Palmer and Braswell, 1995). NATURE SERVE GLOBAL HABITAT COMMENTS: Habitats diverse; semiarid to damp, lowlands to mountains, grasslands to open forests and forest edges, wilderness to suburban. Secretive; hides in logs and stumps
and under surface cover. Sometimes found in the open. Hibernates underground or in rock crevice. Eggs are laid in soil, sawdust piles, under surface cover.
