The Shenduruny wildlife sanctuary is home to numerable animals like elephants, wild boar, tigers, leopards, bisons, langurs, sambar, lion-tailed macaques and deer. West coast tropical evergreen forests also inhabit the sanctuary. It is interesting to note that the Shenduruny forest gets its name from a widespread species of tree called Chenkuruny (Gluta travancoria). In the heart of the forest is located a 26 sq km artificial lake formed by the Parappar dam built across the Shenduruny and Kulathupuzha rivers. The lake forms one of the important attractions of the region.
