Comments: Pacific treefrogs occupy a wide variety of habitats, including grassland, chaparral, woodland, forest, and farmland. They live on land except during the breeding season. Females deposit eggs in shallow water of marshes, lakes, ponds, ditches, reservoirs and slow-moving streams (Stebbins 2003), sometimes in weakly brackish water (Gardner, 1995, Herpetological Review 26:32).
Pacific treefrogs spend most of their time on the ground, but after the breeding season they commonly bask on the leaves of broad-leaved evergreen shrubs far from water, and sometimes they climb high into trees.
See Munger et al. (1998) for quantitative information on habitat in southwestern Idaho.
