Assessment Information [top]

Red List Category & Criteria:	Least Concern     ver 3.1
Year Assessed:	2008

Reviewer/s:	Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
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/least concern (Baillie and Groombridge 1996)

Systems:	Terrestrial

Threats [top]

Major Threat(s):

There are no major threats to the species although deforestation and conversion of forest habitats to agriculture and pasture have severely reduced Atlantic forest habitats, which is suspected to be reducing populations.

Conservation Actions [top]

Conservation Actions:

This species occurs in several protected areas. More research is necessary to determine the actuall range, verify its occurrence in protected areas and tolerance to habitat modification.
