Breeding Range Map
Amphibians do not migrate as some birds and mammals, so the colored areas depict the predicted range for the Pacific treefrog year-round. The habitats were identified using 1991 satellite imagery, other datasets and experts throughout the state, as part of the Washington Gap Analysis Project.

Distribution and Habitat Requirements
The Pacific treefrog is the most common and widespread frog in Washington State (Slater, 1941). It can be found in almost any habitat where there are suitable breeding waters (Nussbaum et al., 1983) which are usually small ponds. Lakes and rivers were selected because more suitable smaller water bodies or backwaters often occur at their edges.
