Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(ii,iii) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Francis, C. & Gumal, M.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
This species is assessed as Endangered because its extent of occurrence is 1,200 km2, it is known from only two islands of the Mentawai Archipelago and there is continuing decline in quality and extent of habitat. It could also meet the B2 criteria, but there is presently insufficient information on remaining habitat to assess this. This species could be Critically Endangered based on population size reduction or current population size, given the recent and extensive habitat loss on the islands where it occurs, but there is presently insufficient information to assess this.
