Evaluator/s:

McKnight, M. (Global Mammal Assessment Team) & Amori, G. (Small Nonvolant Mammal Red List Authority)

Justification:
This species is listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

History:

1996

–

Lower Risk/near threatened (Baillie and Groombridge 1996)

Geographic Range [top]

Range Description:	This species occurs from central Durango south to north Oaxaca, Mexico (Patton 2005). Its known altitudinal distribution is from 950 m to 2,850 m (Jones and Genoways 1975).
Countries:	Native: Mexico

Population [top]

Population:	It this species is relatively common throughout its range. However, in the Valley of Mexico, the population is considered extinct.
Population Trend:	Stable

Habitat and Ecology [top]

Habitat and Ecology:	This species occurs primarily in semi-arid or arid environments characterized by short grasses and clumps of prickly pear, nopal, cactus, or low thornbrush interspersed with open patches of bare ground. Little has been recorded on foods habits. Some captured individuals had seeds and small green leaves or young plants in their pouches. The species uses burrow systems with a single entrance. A female recorded in June had two embryos, and two females taken in October had three embryos each; also some juveniles were reported in April, August, and November. From this information it is concluded that the reproductive period is prolonged (Jones and Genoways 1975).
Systems:	Terrestrial
