Assessment Information [top]

Red List Category & Criteria: Vulnerable C1 ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): IUCN SSC Antelope Specialist Group
Reviewer(s): Mallon, D.P. (Antelope Red List Authority) & Hoffmann, M. (Global Mammal Assessment)
Listed as Vulnerable as the population numbers an estimated 5,000 animals total, and continues to decline in the face of ongoing bushmeat hunting and habitat loss in its range, such that a decline of 10% in three generations (estimated at 15 years) is likely to be easily met. If the population decline becomes steeper, it will approach Endangered status under criterion C, since it has already reached the threshold of <2500 mature individuals.
