The Sanjay-Dubri tiger reserve is spread over an area of 1674.502 Sq. km. and consists of Sanjay National Park and Dubri Sanctuary, along with buffer areas taken from Sidhi and Shahdol districts. It lies in the northeastern part of the state of Madhya Pradesh and is bordered by the Guru Ghasidas National Park on the south, of which it was a part before the formation of Chhattisgarh in the year 2000. The reserve is part of the Bandhavgarh-Sanjay-Guru Ghasidas-Palamau landscape and has been identified as one of four potential tiger meta-state populations landscapes which require conservation inputs. The reserve's landscape is mostly flat in the Dubri Wildlife Sanctuary and gently undulating in the Sanjay National Park, with an altitude range of 200-500 metres. Several perennial rivers flow through the reserve, including the Gopad, Banas, Mawai, Mahan, Kodmar, and Umrari. This reserve's significant degree of variety is due to its unusual phytogeographical location, terrain, and physiography. The forest vegetation type is mainly north Indian moist deciduous peninsular sal (3C/C2e) and North Indian dry deciduous peninsular sal (5B/C1c) (Champion & Seth, 1968).
