Population [top]

Population:	This species is common in suitable habitat within its range.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	This species occurs in areas with dry climate, although heavy rains are frequent during summer and some snow falls on upper slopes in winter as late as May. Upper slopes of the mountains primarily are covered with forests of pine (Pinus), and oak (Quercus) with scattered pinabete (Abies religiosa), Douglas fir (Pseudotsuga menziesii), and quarking aspen (Populus tremuloides). At lower levels in the upper Sonoran zone, oaks and many shrubs become dominant. This species has been observed feeding on pine nuts and on a large, green oak. The sex ratio was 8 males : 19 females. Litter size is two to four; pregnant females have been recorded in May, June and July. Lactating females were observed in June, July and August (Best et al. 1993)
Systems:	Terrestrial
