Reviewer(s): McKnight, M. (Global Mammal Assessment Team) & Amori, G. (Small Nonvolant Mammal Red List Authority)
Listed as Least Concern since, although its extent of occurrence is probably less than 20,000 km2, it occurs in an area of extensive, suitable habitat that does not appear to be under threat, has a presumed large population, and is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.
Previously published Red List assessments:
1996 Lower Risk/least concern (LR/lc)

It is probably both diurnal and nocturnal, fossorial, and solitary. It is herbivorous and feeds on underground plant parts, such as tubers and stems, and on above ground parts pulled down from below. The presence of pocket gophers is shown by their shallow foraging tunnels, which appear as low humps snaking between damaged plants.
Systems: Terrestrial
