Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Patton, J., Costa, P., Dunnum, J., Vargas, J., Bernal, N. & Patterson, B.
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, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. There are rapid rates of habitat conversion, so this species may become threatened in the near future.
Previously published Red List assessments:
1996 Lower Risk/least concern (LR/lc)

Threats [top]

Major Threat(s): In Bolivia, there do not appear to be any major threats to this species. The dry forest in Bolivia, Paraguay, and Brazil is rapidly declining due to forest conversion for agriculture, and a pipeline form Brazil will increase this threat (J. Patton pers. comm.).

Conservation Actions [top]

Conservation Actions: It is probably present in several protected areas in Bolivia. Further research is needed into the distribution and taxonomy of this species.
