Metadata (Data about data or how the map was made)

Usually found in open sagebrush-grass habitat, but also enters pastures and abandoned fields. Occurs in high densities along banks of canals, around springs, and adjacent to irrigated fields. Prefers sandy soil for digging. On the Hanford Nuclear Reservation site found at all elevations from the Columbia River up to 3600 feet. Most abundant in sagebrush above 2000 feet in the Basin.

Core area was the Central Arid Steppe zone with all non-forested habitat good. Not really associated with forested zones but may occur in large patches of sagebrush at the lower edges of Oak and Ponderosa Pine zones.
