| Of all North American pocket gophers, the Northern Pocket Gopher has the widest distribution, across most of the western United States and south-central Canada, and it occurs in the greatest variety of habitats. Only habitats with closed canopy and sparse groundcover are avoided. Northern Pocket Gophers are prodigious diggers, using both their front feet and their ever-growing incisors. Their burrow systems are elaborate, and depending on where they are, can be beneficial, aerating the soil, or a real problem for farmers.
