Assessment Information [top]

Red List Category & Criteria:

Near Threatened ver 3.1

Year Assessed:

2008

Assessor/s

Bidau, C., Lessa, E. & Ojeda, R.

Evaluator/s:

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

Justification:
Listed as Near Threatened because this species is probably in significant decline (but probably at a rate of less than 30% over ten years) because of widespread habitat loss through much of its range, thus making the species close to qualifying for Vulnerable. In the future this species will likely qualify for Vulnerable under B1ab+2ab. Further research is needed to better understand the impacts of habitat conversions on population decline.

History:

1996
