Distribution and Habitat Requirements
This species occurs in eastern Washington, but it is believed that the Columbia River has been a barrier to its expansion into Benton, Kittitas and Yakima counties. Very little is known about this species in the Northwest except that it spends most of its life underground. This species lives in the shrub-steppe. The Canyon Grassland zone is a mystery because the species is so poorly known in this region.
The Columbia Basin, Northeast Corner, Okanogan Highlands and areas in the East Cascades ecoregions were selected. The Blue Mountains were excluded from this model. In the mesic steppe zones, good habitats were open water and wetlands. Irrigated agriculture, non-forested habitats (except sparse vegetation) and open-canopy conifer were suitable if appropriate microhabitats existed. The drier Central Arid Steppe zones were treated similarly, except that non-forested grasslands and shrub savannas were excluded. Closed-canopy forests were included in the Columbia Basin. The Ponderosa Pine and Oak zones were modeled like the mesic steppe zones except that all forests were excluded and both zones were marginal.
