Habitat and Ecology [top]

Habitat and Ecology:It is found in various habitats. It is common in coniferous forests but also uses clearcuts, deciduous woods, sagebrush, riparian zones, and in western regions may even occur in alpine tundra. Winter nest is up to one metre below ground surface. Summer dens typically are in hollow logs or stumps, in rock piles, or under debris, evacuated burrows. Also nests in tree cavities above ground.

Breeds in early spring. Gestation lasts 31 days. Litter size is 2-7 (average 5-6). Only one litter per year. Second litter may be produced if first fails. Sexually mature in first spring. Home range varies from less than an acre to four acres (Banfield 1974). Feeds mostly on seeds, nuts, fruits, and acorns. May be active throughout the day, but prefers the sunny midday hours. Begins semi hibernation in late October. Fully active by mid-March. May be active on warm winter days.
Generation Length (years):3
