Assessment Information [top]

Red List Category & Criteria:

Least Concern ver 3.1

Year Assessed:

2008

Assessor/s

Oates, J.F. & Bearder, S.

Evaluator/s:

Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)

Justification:
This species has a relatively restricted range, but does relatively well in secondary forest. Habitat change has slowed in some parts of its range, and this species is not actively hunted. As it remains locally common in appropriate forested habitats, and there is no evidence of a significant decline that would warrant listing in a higher category of threat, the species is here listed as Least Concern.

History:

1996	–	Lower Risk/near threatened (Baillie and Groombridge 1996)
1988	–	Not Threatened
