An Assessment of Endangered Primates

In an unprecedented effort, over a hundred field primatologists have pooled their knowledge to create the world's most comprehensive survey of threatened primates — and the results are a dire mosaic of crisis and hope

Their assessment was one part of a global analysis of mammal species. The results of the primate component were released to coincide with the 22nd Congress of the International Primatological Society, in order to highlight the severe dangers now facing the world's primate fauna.

The analysis reveals that:

Over 70% of Asian primates are threatened with extinction, and at least two dozen taxa are Critically Endangered. Virtually all gibbons are threatened with extinction — and one of the rarest subspecies, the Yunnan white-handed gibbon, may already be extinct.

All great apes — all gorillas, all chimpanzees, all orangutans, all bonobos — are either Endangered or Critically Endangered. Across all primate taxa, a full 48% are threatened — nearly half of all primates, in harm's way and likely to go extinct in our own lifetime.
