From Wildlife Extra:
Huge populations discovered of two of Asia’s rarest primates
Cambodia conservation area contains tens of thousands of threatened monkeys
August 2008. Just weeks after announcing the discovery of an unkown population of 50,000 western lowland gorillas, the Wildlife Conservation Society report has revealed large and previously unknown populations of two globally threatened primates in a protected area in Cambodia.
The survey counted 42,000 black-shanked douc langurs along with 2,500 yellow-cheeked crested gibbons in Cambodia’s Seima Biodiversity Conservation Area, an estimate that represents the largest known populations for both species in the world.
A new population of the extremely rare Tonkin snub-nosed monkey, so-called because of its unusual and distinctive up-turned nose, has recently been discovered in a remote forested area of northern Vietnam: here.
