HABITAT DESCRIPTION: |
|
Palmer and Braswell (1995) recognize an introduced but established population on the coastal plain in Onslow County. Eggs are laid in nests dug an average 15 cm deep (Martof et al 1980). NATURE SERVE GLOBAL HABITAT COMMENTS: Open arid and semiarid regions with sparse vegetation; grass, cactus, scattered brush or scrubby trees.
Soil may vary in texture from sandy to rocky. Burrows into soil, enters rodent burrow, or hides under rock when inactive. Sheffield and Carter (1994, Herpetol. Rev. 25:67-68) reported individuals that climbed 1-2 m up tree trunks when soils were wet after heavy rains. Eggs are laid in nests dug in soil or under rocks (Collins 1982).
