The Periyar Wildlife Sanctuary is one of the 16 Project Tiger Reserves in India located in the in the Cardamom Hill Ranges in the southernmost part of western Ghats in Kerala.
A dam that was constructed on the River Periyar in 1895 resulted in the adjoining forests being granted protection by the Maharaja of Travancore. The resulting Periyar Lake and its surrounding forests, provide protection to the animals within. The forests are a mixture of deciduous, semi-evergreen, and evergreen trees with patches of marsh and grasslands.The picturesque lake in the heart of the sanctuary was originally 26 sq km but now spans an area of 55 sq km. Animals started trooping in due to this perennial source of water, which initially led to the submersion of large tracts of forestland. Eventually the adjoining forests were granted protection by the Maharaja of Travancore. Post-1975 Periyar finds itself in the enviable position of being a national park as well as a protected tiger reserve
Although a Tiger Reerve, the Sanctuary is most famous as Elephant country. About 800 reside within these natural surroundings. Apart from Elephants, other animals here are the Gaur, Wild Pig, Sambhar, Mouse Deer, Indian Wild Dog and sometimes the Tiger, which are 40 in number.
