AVIFAUNA: A total of 160 species of birds has been recorded in a survey conducted by the Nature Education Society, Trichur, (NEST) in collaboration with the Kerala Forest Research Institute (Nameer 1992). Although no globally threatened species was recorded, five Restricted Range or endemic species were identified. The site lies in the Western Ghats Endemic Bird Area (Stattersfield et al. 1998), one of the biodiversity hotspots of the world. BirdLife International (undated) has identified 15 species which represents biome assemblages of the Western Ghats. This site comes under Biome-10 (Indian Peninsula Tropical Moist Forest). Based on the checklist prepared by NEST (Nameer 1992), nine of these biome species are found at this site. Once more detailed research is conducted, more species of this biome are likely to be found here.
OTHER KEY FAUNA: Out of the 47 large mammals reported from Kerala, 22 are found in Chimmony (Jayson 1997). Rare, endemic and endangered species include Nilgiri Langur Trachypithecus johni, Lion tailed Macaque Macaca silenus, Slender Loris Loris lydekkerianus, Leopard Cat Prionailurus bengalensis, Wild Dog Cuon alpinus, Indian Giant Squirrel Ratufa indica, Asian Elephant Elephas maximus, Gaur Bos gaurus, Mouse Deer Moschiola meminna and Tiger Panthera tigris.
The boundaries of the Chimmony Wildlife Sanctuary were drawn on the basis of physical barriers and ecological continuity was not considered. Extensive Evergreen and Semi-evergreen forests around the Sanctuary which harbour several endangered species, do not come within the limits of any protected area (O. P. Kaler, Wildlife Warden, 2001, pers. comm.). Beyond the eastern boundary of Chimmony lie large tracts of evergreen forests of Parambikulam. To the south and southwest are the evergreen forests of Vazhachal and Chalakudy Forest Division. These areas have to be included in the Anamalai- Anamudi Conservation Unit, thus joining Chinnar and Indira Gandhi Wildlife sanctuaries in the east to Peechi Wildlife Sanctuary in the west. Fortunately, Chimmony Wildlife Sanctuary is free from human habitation, except for the former Kallichitra tribal settlement. This settlement was relocated when Chimmony reservoir was filled up. However, the tribals are not happy in their new settlement and want more land and compensation. There is no cultivation inside the Sanctuary and the pressure of cattle grazing is also low.
