Mount Halimun Salak National Park

Mount Halimun Salak National Park is a 400km2 conservation area in the Indonesian province of West Java on the island of Java. Established in 1992, the park comprises two mountains, Mount Salak and Mount Halimun. It is located near the better known Mount Gede Pangrango National Park, and close to the city of Bogor and the Bogor Botanical Gardens.
The park contains water catchment areas shielded from urban populations an agricultural areas to the north, as well as several endangered animals and rare birds

Geography 

Its mountain tops reach 1,929 metres and are often mist-shrouded, while its valleys are thought to hide much that remains to be discovered.[3] Mount Salak is a critical water catchment area for its very high rainfall.The park is an amalgamation of two important ecosystems at Halimun and Mount Salak, which are connected by an 11-kilometer forest corridor

Communities in the park

The Kesepuhan traditional community is a group of around 5,300 people who live in the southern part of the park. Their main village is Ciptagelar.

Ecology 

The lower zones hold secure populations of the endangered West Javan Gibbon (Hylobates moloch moloch) - a sub-species of the Silvery Gibbon. Mount Halimun is its most secure habitat, but its range is restricted to a thin ring around the park as the species is not found above 1,200 metres. Javan Lutung (Trachypithecus auratus), and other endemic species are evident; about half its 145 known bird species are rarely seen elsewhere in Java.
Chevron Pacific Indonesia has been involved in some activities to restore some parts of the Mount Halimun national park
