Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: Its geographic range includes wooded areas and woodland edges (including woodlots in prairies), usually within a few hundred metres of water. It is often found in recently disturbed areas with abundant shrubs, herbaceous growth and vines. It is an arboreal and terrestrial species. When inactive, it may hide in tree holes, under bark, under leaves or under tree roots. In Tennessee, frogs associated with knothole cavities in trees in fall were not there after mid-November (Ritke and Babb 1991). Eggs are laid and larvae develop in temporary or permanent waters of flooded ditches, puddles, river sloughs, creeks and small ponds, where there are woody branches or extensive herbaceous growth along the edges. Males call from water surface or from vegetation or ground near water. Individuals generally breed in the same site in successive years (Ritke et al. 1991).
Systems: Terrestrial; Freshwater
