Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(i,ii,iii) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Zeballos, H. & Vivar, E.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
This species is listed as Vulnerable because its extent of occurrence is less than 20,000 square kilometers; it is known from fewer than ten locations, and there is continuing decline in the extent and quality of its forest habitat. The threats to this species are increasing as the foothills of the Andes and Andean valleys are increasingly targeted for logging and human settlement.
