Shrubs and tree seedlings occasionally are eaten. Gophers may damage young conifers. Food, such as roots of Lewisia and small Brodiaea, may be stored in underground cavities. Complex underground tunnel systems are constructed, breaking surface where plants are taken and earth is pushed up in mounds. A nest of dried vegetation is constructed in an underground nest chamber.
Water is obtained from food.
Deep, friable soils with moderate herbaceous cover are preferred. Active throughout the day, although more active at night. Adult males are aggressively solitary toward other males. Adult male territories usually include several female territories. Gestation period unknown, but probably 3-4 wk.
