Forests, Biosphere Reserves & Wildlife Protected Areas

India's botanical and faunal biodiversity is protected across a network of National Parks, Wildlife Sanctuaries, Conservation Reserves, and Biosphere Reserves established under the Wildlife Protection Act of 1972. According to the India State of Forest Report (ISFR), tropical moist and dry deciduous forests constitute the largest forest categories by area, followed by tropical wet evergreen forests in the Western Ghats and North-East. The country hosts four globally recognized biodiversity hotspots: the Western Ghats, the Himalayas, Indo-Burma, and Sundaland. Flagship conservation programs such as Project Tiger (1973) and Project Elephant (1992) maintain critical ecological corridors, while 18 Biosphere Reserves (12 within UNESCO's World Network) safeguard regional biomes.
