About one-sixth of Nagaland is covered by tropical and sub-tropical evergreen forests—including palms, bamboo, rattan as well as timber and mahogany forests. While some forest areas have been cleared for jhum cultivation, many scrub forests, high grass, reeds; secondary dogs, pangolins, porcupines, elephants, leopards, bears, many species of monkeys, sambar, harts, oxen, and buffaloes thrive across the state’s forests. The great Indian hornbill is one of the most famous birds found in the state. Blyth’s tragopan, a vulnerable species of pheasant, is the state bird of Nagaland. It is sighted in Mount Japfü and Dzükou Valley of Kohima district, Satoi range in Zunheboto district and Pfütsero in Phek district. Of the mere 2500 tragopans sighted in the world, Dzükou valley is the natural habitat of more than 1,000.
Mithun (a semi domesticated gaur) found only in the north-eastern states of India, is the state animal of Nagaland and has been adopted as the official seal of the Government of Nagaland. It is ritually the most valued species in the state. To conserve and protect this animal in the northeast, the National Research Centre on Mithun (NRCM) was established by the Indian Council of Agricultural Research (ICAR) in 1988.
