The Nilgiris, forming a part of the Nilgiris Biosphere Reserve in the Western Ghats is home to moist, dry, evergreen and montane (shola) tropical forests. The Western Ghats, and the Nilgiris in particular, harbour a wealth of flora and fauna; much of which is restricted to the region. e.g. the endagered lion tailed macaque and the Nilgiri tahr. The Nilgiris forest ecosystem is, however, under pressures, e.g. from tea and coffee plantations, illegal, logging and commercial tree plantations with exotics initiated by the Forest Department. It also has a significant tribal population, dependent on natural resources for their livelihood; including the only surviving hunter-gatherers of the Indian sub-continent the Sholanaikans in the New Amarambalam region of Nilgiris. Given its distinct character, the Nilgiris forms part of the Nilgiri Biosphere Reserve (declared under the Man and Biosphere Programme of UNESCO).
