Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
This species is listed as Least Concern in view of its wide distribution, presumed large population, however, restricted to rock formations. It occurs in a number of protected areas, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category. This species is hunted and should be periodically evaluated for impacts of this threat.
Previously published Red List assessments:
2000 Data Deficient (DD)
1996 Lower Risk/least concern (LR/lc)

Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: Species is a habitat generalist (Cofre and Marquet 1999). Inhabits rocky mountain areas as well as rock outcrops in steppe habitat (Galende and Trejo 2003). This herbivorous species is specialized and restricted to rocky habitats where it colonizes rock crevices. Available habitat is patchy (Walker et al., 2003). It occurs up to 4,800 m asl (Barquez et al. 2006)
Systems: Terrestrial

Threats [top]

Major Threat(s): It is locally hunted by people for meat and fur although, in general, this does not significantly impact populations (Barquez et al. 2006). There appear to be no major threats to this species.
