Thanthai Periyar Wildlife Sanctuary

Thanthai Periyar Wildlife Sanctuary is a proposed protected area located along the area straddling both the Western Ghats and Eastern Ghats in the Erode District of the Indian state of Tamil Nadu. The sanctuary was notified by Government of Tamil Nadu in March 2023 and will become the 18th wildlife sanctuary in the state. Covering an area of 801.15 km² (309.33 sq mi), the sanctuary spans parts of Gobichettipalayam and Anthiyur taluks in Western Tamil Nadu.

The proposed sanctuary serves as a critical ecological corridor, linking the Nilgiris Biosphere Reserve with Cauvery South Wildlife Sanctuary, thereby facilitating the safe movement of wildlife such as elephants and tigers. Additionally, the sanctuary connects to the Kollegal forests in the neighboring state of Karnataka and forms a key junction where the Eastern and Western Ghats merge, enhancing regional biodiversity and ecological integrity.
