Mudumalai Wildlife Sanctuary & National Park is situated at the tri-junction of Tamil Nadu, Kerala and Karnataka on the North Eastern Slopes of the Nilgiris part of Western Ghats descending to the Mysore Plateau. An erstwhile game reserve, Mudumalai was declared a wildlife sanctuary with a 62 sq KM area in the early 1940 by the then Madras Presidency. With Bandipur Tiger Reserve (Karnataka) in the north, and Wayanad Wildlife Sanctuary (Kerala) in the west the region forms a single, continuous viable habitat for a varied range of wildlife and is a part of the Nilgiri Biosphere Reserve. While Mudumalai’s western half receives the southwest monsoon, the eastern tracts receive the relatively gentler north-east monsoon which results in a diversity of vegetation types and typical migration of herbivores.
