Halimun and Salak Mountain contain some of Indonesia’s largest remaining lowland and montane forest.

This survey aims to assess the present status of the four primate species -the Javan Gibbon (Hylobates moloch), Grizzled Leaf Monkey (Presbytis comata), Silver Leaf Monkey (Trachypithecus auratus), and Crab-eating macaque (Macaca fascicularis) in Gunung Halimun and Salak National Park.

The project team will then develop a conservation strategy to increase their protection through appreciation of their value by local people and an ecotourism programme for visitors.
