Biology and ecology

This species occurs in forests, chaparral, meadow margins, and sagebrush, especially in areas with many rocks or forest litter that provides shelter. It is associated with many kinds of coniferous trees, aspen, and manzanita. The squirrels hibernate in dens that can reach up to 100 feet in length although they are typically shallow in depth. The breeding season commences when males and females emerge from hibernation in the spring. Most broods are born in July. A female has two to eight young per litter, with an average of five. There is no paternal care of the offspring. Juveniles resemble adults by 40 days of age. The life span of this ground squirrel is up to about seven years.
