URL: http://animaldiversity.ummz.umich.edu/accounts/geomys/g._bursarius$narrative.htm

Geomys bursarius is found in open to sparsely wooded areas. It prefers deep, sandy, crumbly soils, and its distribution tends to be limited by soil type. Because of this preference, the distribution of Geomys is often patchy, closely tracking the local soils.

Near El Paso, these gophers are especially common along irrigation ditches in the sandy river-bottom area. They seemingly cannot tolerate clayey or gravelly soils, a characteristic common to all species of Geomys. Their mounds are large and conspicuous, and often one animal will throw up 20 to 30 of them in a relatively short time.

This pocket gopher typically inhabits sandy soils where the topsoil is 10 cm or more in depth. Clayey soils are usually avoided. These gophers live most of their solitary lives in underground burrows, coming to the surface only to throw out earth removed in their tunneling and to forage for some items of food.
