Red List Category & Criteria: Vulnerable C1 ver 3.1
Year Published: 2008

Estimated numbers were 17,000, with ca. 60% in protected areas. The population is therefore <10,000 mature individuals and the continuing decline is expected to exceed 10% over 3 generations (21-24 years). Current trends will eventually result in the Fringe-Eared Oryx becoming confined to areas such as Tarangire and Mkomazi in Tanzania and parts of south-eastern Kenya, where pressures of poaching and encroachment by settlement and livestock are controlled sufficiently to enable viable oryx populations to persist.
