|Population:||This species is locally common in a naturally fragmented distribution.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||It inhabits various rocky habitats: woodlands of pinyon-juniper and associated shrubs, rubble slopes, slickrock; may use trees and shrubs for cover; burrows beneath boulders or shrubs (Armstrong 1982). May sometimes use sandy habitats (blackbrush-Indian ricegrass) adjacent to pinyon-juniper or rocky areas. Easily climbs on cliffs and in woody vegetation. Nest sites are associated with piles of broken rock or crevices in solid rock. |
In southeastern Utah mating occurs February-March; gestation lasts 30-33 days; young are born during first half of April, above ground in May; average litter size is 5.2 (Wadsworth 1969). Weaning is completed in 6-7 weeks. Sexually mature in 10-11 months; females give birth to their first litter when about one year old (Burt and Best 1994).
Home range in southeastern Utah was estimated at 0.4-1.3 ha (Wadsworth 1972). Diet includes mainly seeds (of trees, shrubs, and herbaceous plants), also flowers and insects, and, seasonally, small or large amounts of green vegetation; opportunistic, takes advantage of handouts and human food refuse in campgrounds (Armstrong 1982, Wadsworth 1972, Burt and Best 1994).
Activity peaks in morning and late afternoon (Armstrong 1982), especially in summer when it avoids midday heat. Seldom seen above ground mid-November to mid-February (Armstrong 1982).
