Namdapha National Park, Kamlang Wildlife Sanctuary and Jairampur Forest Division are located within India’s northeastern frontier state–Arunachal Pradesh.

Among the last great remote wilderness areas of Asia, Namdapha and its adjoining areas, is flanked by the Patkai hills to the south and south-east and by the Himalaya in the north.

The area lies close to the Indo-Myanmar-China trijunction. Forests are contiguous across the international boundary with Myanmar, with several adjoining protected areas, including the huge recently declared Hukawng Valley Tiger Reserve (Rabinowitz 2001, 2004). The entire area is mountainous and comprises the catchment of the Noa-Dihing River, a tributary of the great Brahmaputra river which flows westwards through the middle of Namdapha.
