Abstract: The North-East India region is the “gateway” for much of India’s flora and fauna as the ecosystem components exhibit great dynamism and has a relatively complex biogeography. It is considered as a genetic treasure house of plants, animals and microbial resources. The region fills in as a rich archive of plant and animal riches in different biological frameworks. Forests in this area vary from tropical, temperate to alpine meadows and cold deserts, having highest diversity of biomes.
