Its northern boundary runs along the international border with Bhutan. The Sinchula hill range lies all along the northern side of BTR and the eastern boundary touches that of the Assam state. National Highway No.31 C roughly runs along its southern boundary. It is the easternmost extension of extreme bio-diverse North-East India and represents highly endemic Indo-Malayan region. The fragile "Terai Eco-System" constitutes a part of this reserve. The Phibsoo Wildlife Sanctuary of Bhutan is contiguous to the north of BTR. Manas National Park lies on east of BTR. BTR, thus, serves as international corridor for Asian elephant migration between India and Bhutan. To the south-west, the Chilapata Forests form an elephant corridor to the Jaldapara Wildlife Sanctuary. The reserve encompasses as many as eight forest types. The divisional headquarters is located at Alipurduar. The forest is divided into two divisions: East and West. Buxa Fort is an important landmark for this reserve. This fort was captured by British-India in 1865 after the Bhutan War from Bhutan. Later this fort was used as a detention camp for Indian freedom fighters during the Indian freedom movement.
