But many of these species are severely threatened by habitat degradation and hunting driven by trade and consumption for meat and traditional medicine. A quarter of the species in the region are classified as Critically Endangered, and about half are Endangered in the IUCN Red List. In the latest Red List assessments, a quarter of the primate species in the region showed increased extinction risk compared to previous assessments, while the the rest showed no reduction in extinction risk.  Urgent and targeted conservation efforts must be taken to protect the incredible diversity of primates in the Greater Mekong.
