Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(ii,iii)+2ab(ii,iii) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Lunde, D., Duckworth, J.W., Lee, B. & Tizard, R.J.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Justification:
Listed as Vulnerable, because its extent of occurrence is less than 20,000 km2 and its area of occupancy is less than 2,000 km2, it is known from only the three islands belonging to the Mentawai Archipelago, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its forest habitat.
