Predicted Distribution
Amphibians do not migrate as some birds and mammals, so the colored areas depict
the predicted range for the Northern Leopard Frog 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 Northern leopard frog in Washington State occurs around marshes and potholes
in steppe and dry forest (Nussbaum et al., 1983). However, little is known
of its current status in the State. It once apparently occurred in much of
the Columbia Basin and was common on the Columbia National Wildlife Refuge,
but it appears to have be extirpated from much of the Basin. It may be restricted
to the vicinity of the Crab Creek drainage near Moses Lake. It also occurs
along the Pend Oreille River drainage and vicinity in northeastern Washington.

Models
The Columbia Basin and Northeast Corner ecoregons were selected. The Central
Arid Steppe, Ponderosa Pine and Interior Douglas-fir zones were core. Grand
Fir and Interior Redcedar zones were marginal.
Lakes and rivers were good habitats. Grasslands, shrub savannas, shrublands, open-canopy hardwood and conifer forests were considered suitable if appropriate microhabitats existed.
