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's flora is fully surveyed. Namdapha's 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.
