Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(ii,iii) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Helgen, K. & Aplin, K.
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 not much greater than 5,000 km2, its habitat is severely fragmented and it is experiencing rapid, continuing decline in the extent and quality of habitat. Insufficient information exists on remaining forest to assess whether its area of occupancy is less than 500 km2, but it probably meets the B2 criteria as well. Based on rates of habitat loss, it may also meet A4 criteria for Endangered, but the experts felt uncomfortable making an assumption of a 50% population decline.
