Breeding Range Map
Reptiles do not migrate as some birds and mammals, so the colored areas depict the predicted range for the Short-horned Lizard 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 Western pond turtle is known to inhabit marshes, sloughs, and slow-moving portions of creeks and rivers (Nussbaum et al., 1983). The historic northernmost range for this species in Washington State was the north shore of Lake Washington (Slater, 1962), but there are no recent records from most of the lowlands of western Washington.

This turtle occurs in the Southwest and Southeast Cascades ecoregions and barely into the Columbia Basin ecoregion along the Columbia River. The Canyon Grasslands, Oak and Western Hemlock zones were core.

Good habitats were lakes, marshes, and riparian areas. Grassland, shrublands, shrub and tree savannas were considered suitable if appropriate freshwater microhabitats are available in the Canyon Grasslands and Oak zones.
