 periyar wildlife sanctuary in kerala

Periyar is a protected area, and a nature reserve in the South Indian State of Kerala, set high in the mountains of the Western Ghats along the border with Tamil Nadu. It lies in the districts of Idukki and Pathanamthitta. The protected area covers an area of 925 km², out of which a 350 km² part of the core zone was made into the Periyar National Park and Tiger Reserve, sometimes dubbed the Periyar Wildlife Sanctuary. The park is often called by the name thekkady also. Thekkady is located four km from Kumily, approximately 100 km east of Kottayam, 110 km west of Madurai and 120 km southeast from Kochi.

The area bears a large variety of flora and fauna. Four species of primates are found at Periyar - the rare lion-tailed macaque, the Nilgiri Langur, the common langur, and the Bonnet Macaque.  Other mammals found here include gaur,Bison, sambar (horse deer), barking deer, mouse deer, Dholes (Indian wild dogs), mongoose, foxes and leopards. Also inhabiting the park, though rarely seen, are the elusive Nilgiri tahr.

The Periyar protected area lies in the middle of a mountainous area of the Cardamom Hills. In the north and the east it is bounded by mountain ridges of over 1700 metres altitude and toward the west it expands into a 1200 meter high plateau. From this level the altitude drops steeply to the deepest point of the reserve, the 100 meter valley of the Pamba River. The highest peak is the 2019 meter high Kottamalai.

The sanctuary surrounds picturesque 26 km² Periyar lake, formed by the building of Mullaperiyar Dam in 1895. This reservoir and the Periyar River meander around the contours of the wooded hills, providing a permanent source of water for the local wildlife.

The temperature varies depending upon the altitude and it ranges between 15° Celsius in December and January and 31° Celsius in April and May. The annual amount of precipitation lies between 2000 and 3000 mm. About two thirds of the precipitation occurs during the southwest monsoon between June to September. A smaller amount of precipitation occurs during the northeast monsoon between October and December.
