(Data about data or how the map was made)
= Core Habitat
= Marginal Habitat
Amphibians do not migrate as some birds and mammals, so the colored areas depict
the predicted range for the Spotted Frog (Westside) 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
Recent surveys suggest that the Oregon Spotted Frog as been exterminated from much of its historic range in western Washington.
Historically it was found in marshy edges of ponds, lakes or streams along the Puget Trough. This species was recently split from the Columbia Spotted Frog.
The only known existing populations in Washington State occur in Thurston and Klickitat Counties.
The Puget Trough and Southeast Cascades ecoregions were selected. The Puget Sound Douglas-fir, Oak, and Interior Douglas-fir zones were core areas.
Lakes, rivers and riparian areas were good habitats. Hardwood and hardwood/conifer forests were suitable if appropriate microhabitats, existed.
