Conservation Status: Least Concern.

Brush Deermice occupy rocky and brushy or forested environments in which rock ledges, piles of brush, fallen trees, and boulders offer shelter and denning sites. Although they are reportedly good climbers, they only occasionally build their nests in tree cavities. Within their enormous range, these Deermice are found only at elevations above 2,000 m. They consume many kinds of nuts, seeds, and fruit, including grass seeds, acorns, pine nuts, hackberries, juniper berries, and fir seeds.
