Spread over an exhaustive 1985 square kilometer area, the Namdapha National Park is the largest protected area in the Eastern Himalayan Bio-diversity hotspot located in the north-eastern Indian State of Arunachal Pradesh. Established in 1974 this is the largest National Park of India which is part of the Eastern Himalayan Sub-region harboring the northernmost Lowland Evergreen Rain-Forests of the world. Occupying a large part of the Changlang District in the State of Arunachal Pradesh, Namdapha National Park is very close to the eastern border of India with Myanmar.
The habitat of the Park changes with increase in altitude from sub-tropical broad-leaf forests to sub-tropical pine forests, temperate broad-leaf forests, and to alpine meadows to perennial snow at higher elevations. The areas within the Park have extensive bamboo and secondary forests along with the primary forests of this region. The floristic composition of the Namdapha National Park consists of a varied species of Dicots, Monocots, Lichens, Bryophytes, Pteridophytes, and Gymnosperms. The inaccessibility to a larger portion of the Park has in fact helped to keep these forests in their pristine and virgin state, as nature has made them to be. The lush green under-growths are thick and intertwined as cobwebs spun out of canes, bamboos, wild fruits and a variety of vegetations.
A great variety of fauna, altogether 1,285 species are found to bring this National Park alive. These include 96 species of mammals and 453 species of avifauna, 50 species of reptiles, 25 amphibian, 76 fish species and many others of insects and butterflies. Tigers, Leopards, Snow Leopards, Dhole, Wolves, Asiatic Black Bear and the entire chain of supporting wildlife, including the endemic species of Takin & Bharal are found to inhabit the Park. The primates include the Stump Tailed Macaque, Slow Loris, Hoolock Gibbons, Capped Langurs, Assamese Macaques and Rhesus Macaques. The vast range of avifauna includes the rare and endangered White Winged Wood Ducks, a variety of Hornbills, Jungle Fowls and Pheasants.
