Habitat and Ecology [top]

Habitat and Ecology: Generally a high elevation species. It inhabits alpine and subalpine meadows, sagebrush flats, mixed brush and grass habitats, pastures and croplands. It is usually found in fairly open habitat (Jenkins and Eshelman 1984). It is seldom far from water.

Young are born in underground burrows. Breeding occurs shortly after hibernation. Gestation lasts 23-28 days. Females are reported to produce one litter of 4-12 young, or an average of eight young per litter (Hall 1946). Sexually mature in two years. Lives in colonies. Predators include coyotes, badgers, and weasels.

Feeds primarily on grass, leaves of meadow plants, and seeds. Remains active for longer periods during the spring and summer than are other species of Spermophilus, which live in more arid habitats at lower elevations (Larrison and Johnson 1981). Usually hibernates from late September-May or June (Hall 1946).
Systems: Terrestrial
