Site description (2004 baseline):
AVIFAUNA: R. Sugathan (pers. comm. 2001) is conducting long-term study on the birds of Parambikulam Wildlife Sanctuary. About 131 species of birds have been identified, including some threatened and restricted range species. 214 bird species recorded from Parambikulam Wildlife Sanctuary (Nameer 1994) including some of the globally threatened species. The site lies in the Western Ghats Endemic Bird Area (EBA) (Stattersfield et al. 1998). In this EBA, 16 species have been identified which have restricted range of less than 50,000 sq. km. Most of them are forest birds. Five of these restricted range species are known from this site. Probably more restricted range species are found as the forest cover is extensive, and this site adjoins other IBAs where these species are found. Based on the biome classification of BirdLife International (undated), this site should fall in Biome-10 (Indian Peninsula Tropical Moist Forest). Out of the 15 species of this biomerestricted assemblage, eight have been found at Parambikulam till now. More are likely to occur as they are common in the Western Ghats. Detailed avifaunal investigation is required.
OTHER KEY FAUNA: The Sanctuary harbours almost all representatives of the larger species of peninsular Indian mammals. Major carnivores include the Tiger Panthera tigris, Leopard P. pardus and Indian Wild Dog Cuon alpinus. Large herds of Asian Elephant Elephas maximus are often seen. Herbivores are represented by Gaur Bos gaurus, Sambar Cervus unicolor, Chital Axis axis and Muntjak Muntiacus muntjak. There are reports of Mouse Deer Moschiola meminna. All the four non-human primates found in Kerala are present in Parambikulam: Bonnet Macaque Macaca radiata, Lion-tailed Macaque M. silenus, Nilgiri Langur Trachypithecus johni and Common Langur T. entellus. Sloth Bear Melursus ursinus is quite common. Parambikulam is perhaps the best site to see large herds of Gaur in peninsular India. A small herd of 15-25 Nilgiri Tahr Hemitragus hylocrius is found on Vengoli- Pamban Malai (Balakrishnan and Easa 1986; Mishra and Johnsingh 1994).
This IBA site suffers from a plethora of problems, all related to human activities. Easa and Balakrishnan (1983) have discussed conservation problems in great detail. According to them, cattle grazing in certain areas is a perennial problem, and is increasing due to human settlements. Related to this is the fire during summer months. This is leading to spread of weeds and fire-resistant nonpalatable species. This problem needs detailed study. Perhaps rotational burning, which establishes a mosaic of burnt and unburnt grasslands during the dry season can be tried in the Sanctuary (Easa and Balakrishnan 1983). Stray dogs have become menace to wildlife, especially around Parambikulam, Thunakadavu and Sungam settlements. Mathew et al. (2002) considered raising of teak plantations after clear-felling extensive areas of natural forests as the major disturbance at Parambikulam. However, being a wildlife sanctuary, these plantations are left without much weeding or extraction of miscellaneous tree species and this has led to the formation of mixed stands over years. In the absence of any further disturbance, the altered forest biota is slowly returning to its normal condition.
