Pocket gophers are the only truly subterranean rodents in North America and are rarely observed above ground. They are herbivores that require grasses and forbs for food and well-drained soil for burrowing.

They are generally territorial and solitary outside the reproductive season, and produce one litter per year, with an average litter size of five young. After weaning, female offspring often establish a burrow system nearby, but male offspring disperse.

Burrows include foraging tunnels and chambers for nesting and caching of food. Though territorial, burrow systems are often aggregated in favorable habitat. Pocket gophers are ecologically important as prey items and in influencing soils and plant species diversity, and their burrows are a retreat for amphibians, reptiles, and many invertebrates.

Pocket gopher predators include owls, coyotes, and bobcats.

Conservation

This species is identified as a Priority Species under WDFW's Priority Habitat and Species Program. Priority species require protective measures for their survival due to their population status, sensitivity to habitat alteration, and/or recreational, commercial, or tribal importance. The PHS program is the agency's main means of sharing fish and wildlife information with local governments, landowners, and others who use it to protect priority habitats for land use planning.
