Stephens' woodrat, Neotoma stephensi, occurs only in limited areas of Arizona, New Mexico, and Utah. In Utah, the species is found only in a small region of the southeastern part of the state.
Stephens' woodrats prefer rocky areas with pinion-juniper cover, often building dens among rocks and at the bases of trees. The species is herbivorous, primarily eating the seeds and foliage of juniper trees, although other vegetation is also consumed. Females may have up to two litters of one to five young each year. Stephens' woodrats are primarily nocturnal.
Woodrats, which are native to the New World, can be distinguished from Old World rats by the presence of hair on their tails rather than bare scaly skin.
