Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Hart, J., Oates, J.F., Struhsaker, T. & Thompson, J.
Reviewer(s): Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)
This species is listed as Near Threatened as it is believed that it has undergone a population decline on the order of 20-25% over the last three generations, due mainly to intensive pressure from hunting particularly during the period of the Congo War. This is not sufficient to warrant listing in a threatened category, but further research into the hunting pressures may reveal that this species could qualify as Vulnerable under criterion A, all the more since this species is more heavily hunted than many of the other primates occurring in the Congo basin.
