Assessment Information [top]

Red List Category & Criteria:

Critically Endangered B1ab(iii,v) ver 3.1

Year Assessed:

2008

Assessor/s

Castro-Arellano, I. & Vázquez, E.

Evaluator/s:

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

Justification:
Listed as Critically Endangered because its extent of occurrence is less than 100 km², all individuals are known from a single location, and there is a continued decline in the amount and quality of habitat due to agricultural activities, which likely translates into a loss of mature individuals. Further research is needed to better understand the conservation status and biology of this species.

History:

1996
