Threatened by hunting and habitat loss throughout their range, crested gibbons are some of the most endangered primates on Earth. Cambodia, with its large tracts of relatively intact forest and low levels of gibbon hunting, has some of the last and most important strongholds for gibbons. Little is known about the population size of yellow-cheeked crested gibbons but preliminary studies suggest Virachey National Park, in north-east Cambodia, has the largest and globally most important population of this species.
This project seeks to fill critical knowledge gaps about the population size and distribution of this species in the Virachey National Park landscape. The information will then be used to work with the Cambodian government to ensure better management of the national park by supporting its land zonation, with a particular focus on the conservation needs of gibbons.
