HABITAT DESCRIPTION:
This species spends most of its life in arboreal retreats in forested habitats.

It is both fossorial and arboreal, using tree perches and cavities for shelter during favorable, warm, wet conditions (Conant and Collins 1998, Terwilliger 1991).

NATURE SERVE GLOBAL HABITAT COMMENTS:

Sandy areas in pine savannas and in low wet woods and swamps (e.g., willow oak-blackgum, cypress swamps). When inactive during cold or dry season, burrows under tree roots, vegetation, or in soil; otherwise mostly arboreal and thus dependent on trees near water. Eggs and larvae develop in shallow water of ponds, swamps, and bayheads; in Virginia, breeding sites were temporary ponds dominated by graminoids, beneath open canopies (Mitchell 1991). Reproduction is more successful in semi-permanent ponds due to the absence of predatory fishes. In some areas, deep ponds, such as Carolina Bays and barrow pits, are preferred breeding sites.

 
MODELING DESCRIPTION:

385 Oak Bottomland Forest and Swamp Forest The swamp chestnut oak, cherrybark oak, shumard oak and sweetgum alliance is one representative. Other alliances are dominated by water, willow, and overcup oaks. Swamp forests can be dominated by sweetgum, red maple, and black gum being dominant.
