Namdapha National Park has perhaps the richest diversity of flora and fauna in the Indian Subcontinent. This is because of its biogeographical location within the Indo-Chinese subregion and its great altitudinal variation, from 4,500 meters at Daphabum, highest point, to 200 meters in the lowest valleys. The park is largely mountainous and is drained by the noa-Dehing, Deban and Namdapha rivers. In the lower levels grow a tangled profusion of tropical rainforests, with huge Hollock, Hollong and Mekai trees intermixed with giant creepers, tall cane and dense bamboo stands. Higher up are the deciduous forests, with temperate and alpine forests higher still, where Oak, Magnolia, Pine, Betula and Rhododendrons grow in profusion. Namdapha is a botanical haven, with over 150 tree species and many flowers and orchids, including the Blue Vanda, one of the rarest orchids. It will be many years before Namdapha&39s flora is fully surveyed. Namdapha&39s birdlife includes the Satyr Tragopan, Kalij and Monal Pheasants, Giant Hornbill, Forest Eagle Owl and the rare White-winged Wood Duck. principal reptiles include the Indian Python, Reticulated Python and King Cobra. For mammal watchers, the park boasts no fewer than four large cats- Tiger, Leopard, Clouded Leopard and Snow Leopard. It also has a good population of the Hoolock Gibbon.
Namdapha Tiger Reserve and National Park at the eastern tip of India is the last true wilderness you will find anywhere in the old world. Thick, impenetrable tropical rain forest growth covering an area of 1985.23 square kilometers forms the core of this natural paradise. Namdapha lies along the turbulent Noa-Dihing River at the international border between India and Myanmar within Changlang District in the state of Arunachal Pradesh in the northeast India. It was declared a Tiger Reserve in 1983.
The areas vegetation may be broadly classified into tropical, temperate and alpine vegetation stretching from monsoon forests right up to the snows. The valley is covered with a mix of Assam valley Tropical Rain forest and North Indian Tropical Moist Deciduous forest. The avifauna is a unique mix of Himalayan, Sino- Tibetan and Indo-Burmese forms. The mountainous terrain, criss-crossed by innumerable streams supports a subtropical humid climate sustaining some of the best mamallian fauna in the sub-continent. More than 60% of the land mammals genera found in India is represented in Namdapha and it is the only place in the world where you can find 4 big cats in one area.
Namdapha is justly a birding paradise with more than 400 speciess represented with some only found in this area in India. From Ibisbills and White-bellied Herons on the Noa-Dihing, to Blyth’s Tragopans, Blue-naped Pittas, Snowy-throated babblers, Cochoas, Ward’s Trogons, Beautiful Nuthatches, Rufous-necked Hornbills ~ Namdapha is the last word in exotics and the rare.
Tucked away in the northernmost state of Arunachal Pradesh is the Namdapha National Park.Three major rivers drain this area and flow into the Noa Dihing, a tributary of the Brahmaputra. The Park largely inaccessible has diverse habitats and flora and fauna that are typical of this area.The majestic gaur or mithun, elephant, Himalayan black bear, takin, the wild goat peculiar to the Patkoi range, musk deer, slow loris, binturong and the red panda are all found here.
The predators include the tiger, leopard, the rare snow leopard andclouded leopard in the higher reaches of the hills. A number of primate species are to be seen in the Park, such as the Assamese macaque, pig-tailed macaque, stump-tailed macaque and the distinctive hoolock gibbon.Hornbills, jungle fowl and pheasants flap their noisy way through the jungle, which harbors other colorful bird species. The inaccessibility of the greater part of the Park has helped to keep the forests in their pristine state.This is also a Tiger Reserve under Project Tiger.
