|Population:||This species is common. Reported population densities are typically low (3/ha in forest, 5-12/ha in adjacent meadow in Washington). Populations may be highest in parks where human refuse is available as food.|
|Habitat and Ecology:||
It inhabits talus slides and clearings; krummholz; closed coniferous forest, pine woodland, and adjacent open meadows and sagebrush steppe (Trombulak, in Wilson and Ruff 1999). Remain in underground burrow when inactive (Trombulak 1988).
Young are born in underground burrows. Gestation lasts 28 days. Litter size is 1-5 (average four); one litter per year (Trombulak 1988). Females may breed as yearlings, males usually not until second year. Juveniles emerge from natal burrows in July-early August (Trombulak 1987).
Diet includes fungi (especially in fall), green vegetation, seeds, small fruits, carrion. Generally forages on ground, may climb into bushes and conifers. Emergence from hibernation varies among years from mid-April to mid-May; yearlings emerge 1-2 weeks later than adults. Adults and yearlings end activity mid-August to late September; juveniles are active into November and early December (Trombulak 1988).
|Major Threat(s):||There are no major threats to this species.|
|Conservation Actions:||The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) lists this species as "Not at Risk" (01Apr1992). In 1992 the species was down listed to the blue list vulnerable species in British Columbia, i.e. those which are not threatened with extinction but may be at risk to disturbance (Harcombe et al. 1994). Its range includes a few protected areas within its range.|
