Fact Sheet: Basic | Advanced | Español Breeding Range Map Reptiles do not migrate as some birds and mammals, so the colored areas depict the predicted range for the Gopher snake 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.   Observations

Distribution and Habitat Requirements
The Gopher snake occurs in a lot of different habitats, including prairies, conifer forests and deserts, but it seems most common in semi-arid brushy areas adjacent to farms (Nussbaum et al., 1983). Sweet (1985) found that they were more common that rattlesnakes in open grassland habitats.

Models
The Southeast, East Central and Northeast Cascades, Columbia Basin, Okanogan Highlands and Northeast Corner ecoregions were selected.

All steppe, Ponderosa Pine and Oak zones were core, except that Ponderosa Pine was marginal in the Northeast Cascades.

Good habitats were rivers and riparian areas with all types of wetland vegetation, soil conservation reserve areas, grasslands, shrublands, shrub and tree savannas and open-canopy hardwod/conifer and conifer forests.
