Location

Namdapha Tiger Reserve is situated in south-eastern Arunachal Pradesh along the India–Myanmar border. It forms one of the most intact forest landscapes in Asia and is part of the Eastern Himalaya Biodiversity Hotspot.

History

Originally declared a Wildlife Sanctuary in 1972, Namdapha became a National Park in 1983 and was included in Project Tiger the same year. Its remote location and vast wilderness have helped preserve exceptional biodiversity and relatively undisturbed ecosystems.

The reserve extends over 2,052.82 sq km, including a core area of 1,807.82 sq km and a buffer area of 245 sq km. Altitude ranges from about 200 metres to over 4,500 metres above sea level, resulting in habitats ranging from tropical rainforests to alpine meadows. This remarkable ecological gradient supports one of the richest assemblages of flora and fauna in India.

More than 450 bird species, numerous butterflies, reptiles and amphibians have also been documented.

Rivers & Water Bodies
