Pocket gopher: burrowing rodents of the family Geomyidae
Pocket gophers are fossorial rodents of family Geomyidae native to North and Central America, recognized for fur-lined cheek pouches, extensive burrows, and important ecological and agricultural impacts.
Overview
Pocket gophers are burrowing mammals of the rodent family Geomyidae. They are often called "true gophers" to distinguish them from several unrelated ground-dwelling rodents that share a common name. Native to North and Central America, these animals are adapted to a subterranean life: compact bodies, strong forelimbs and claws for digging, and external, fur-lined cheek pouches that give the group its common name.

Key characteristics
Typical features include small eyes and ears, short tails, large incisors that can be used for cutting roots and excavating soil, and powerful shoulders. Many species carry food and nesting material in expandable cheek pouches that open outside the mouth; these pouches remain clean and separate from the digestive tract. Pocket gophers are usually solitary and territorial, constructing complex tunnel systems used for feeding, nesting, and shelter.
Biology and ecology
These rodents feed mainly on roots, tubers, and the below-ground parts of plants, although they will also grab aboveground vegetation when accessible. Their digging and tunneling alter soil structure, increase aeration, and redistribute nutrients; this can be beneficial for some habitats but problematic for agriculture and landscaping. Predators include owls, snakes, foxes, and coyotes, which sometimes take gophers when they emerge or from tunnel entrances.
Human interactions and importance
Farmers and gardeners often view pocket gophers as pests because their burrows and feeding damage crops, orchards, and lawns. At the same time, their burrowing can improve soil drainage and create habitat heterogeneity that benefits other species. Control and management approaches vary widely, from exclusion and habitat modification to trapping and targeted removal.
Classification, names, and notable facts
The group belongs to the family Geomyidae and is distinct from several unrelated species commonly called gophers, such as some ground squirrels. The term "pocket gopher" emphasizes their cheek pouches and fossorial habits; see related material on burrowing behavior and general rodent adaptations. The common name is applied to a number of subspecies and regional variants (subspecies) across their range. In cultural references, the state of Minnesota is often associated with the gopher, giving rise to the nickname "Gopher State" and to sports team names and mascots.
