The meaning of Dooars is ‘door to Bhutan’. It is the foothills region of Eastern Himalaya and it widely stretches its area from the Teesta river to the Dhansiri river of Assam. The ecology of the region is ‘Terai-Duar Savanna and Grasslands’. The region was ruled by the Koch dynasty in the long back but later it was under the Kingdom of Bhutan and during British India in 1865 A.D at the time of the Bhutan war it was captured by the British. The region is surrounded by many tea gardens and the prime attraction is its biodiversity. In this region, there are many wildlife sanctuaries, national parks and biosphere reserves like Mahananda Wildlife Sanctuary, Neora Valley National Park, Gorumara National Park, Jaldapara National Park, Buxa Tiger Reserve and many more.
