| Wyoming Pocket Gophers are known only from a small area in south-central Wyoming. These rather small Pocket Gophers seem to prefer loose, gravelly, upland soils, often where greasewood is growing. They usually plug the entrances to their burrows with soil. They were for many years thought to be a subspecies of the Northern Pocket Gopher, but genetic studies suggest that they should be considered a separate species.
Because this species’ range is so limited, the range of individual animals is so small, and so few have ever been found, several organizations have noted that this species is at risk. The US Forest Service has declared the Wyoming Pocket Gopher to be a sensitive species in Region 2 and the US Bureau of Land Management has also included the species on its list of sensitive species. The Wyoming Natural Diversity Database has ranked this species as G2/S2, a reflection of concern that the species is at risk of extinction within the state, and that since no examples have been proven outside the state, such an event would mark global extinction as well.
