Character Abstract
Identification Comments:
Subspecies Comments:
Food Habits:Eats roots, tubers, and some surface vegetation. Mostly forages within their underground burrow system, but occasionally forages on the surface of the ground. During this period, they are at significant risk of predation. Food is collected in external cheek pouches and stored in underground chambers.
Phenology Comments:
Reproduction Comments:Winter nest may be above ground in snow. Gestation probably lasts about 18-19 days (Ingles 1965). Females produce 1 litter of 3-4 young/year. Young are born in July-August (Burt and Grossenheider 1964).
Migration Mobility:
Habitat Comments:Mountain pocket gophers occur in mountain meadows and rocky slopes in pine, fir, and spruce (Wilson and Ruff 1999); in rich moist soil, as well as gravelly or rocky ground. They can generally be found on open forest floor and at the edge of meadows. Mountain pocket gophers are found at high altitudes where temperatures are lower than the habitat of other pocket gopher species.
Ecology comments:Mountain pocket gophers are active throughout the year. They are fossorial and solitary, except during the breeding season. Their underground burrow system may cover 18.6 m2 (200 sq ft) for young animals to 186 m2 (2000 sq ft) for old females. Population density can be 10-35/ha (4-14/acre) and individuals may live up to 4 years in the wild. Overground dispersal is difficult for pocket gophers due to heavy predation. Mountain pocket gophers probably rely on deep snow to allow animals to disperse to new territories. Pocket gophers are ecologically important as prey items and in influencing soils, microtopography, habitat heterogeneity, diversity of plant species, and primary productivity (Huntly and Inouye 1988).
