Northern Grasshopper Mouse (Onychomys leucogaster)

Species Code: ONLE

Legend: = Core Habitat = Marginal Habitat Breeding Range Map The green area shows the predicted habitats for breeding only. The habitats were identified using 1991 satellite imagery, other datasets and experts throughout the state, as part of the Washington Gap Analysis Project.

This mouse is most frequently found in association with sagebrush and dry grasslands in both closed cover (tall sagebrush) and more open sites. May require loose, sandy soil for frequent dust bathing. Records are sparse probably because it is difficult to trap and count.

Three steppe zones, Central Arid Steppe, Canyon Grassland, and Wheatgrass/Fescue zones are core areas. Non-forested habitats were good, except tree savanna which was adequate. Most records are old and may be obsolete due to more recent plowing of the habitats.
