Site description Pulicat lake is an extensive brackish to saline lagoon with associated marshes and a massive freshwater to brackish swamp to the north. There are two connections with the sea; in general, sea water enters the lagoon through the channel at the northern end of Sriharikota Island, and flows back into the Bay of Bengal through the channel at the southern end. The backwaters attract large congregations of the Greater Phoenicopterus ruber and Lesser P. minor flamingos, Spot-billed or Grey Pelican Pelecanus philippensis, Painted Stork Mycteria leucocephala, Grey Heron Ardea cinerea, and species of ducks, teals, terns, gulls and waders. Pulicat is the third most important wetland for migratory shorebirds on the eastern board of India. Sriharikota Island, well protected as it is the satellite launching station of the Indian Space Research Organisation (ISRO), has remnants of Tropical Dry Evergeen Forest of considerable botanical interest (Suryanarayana et al. 1989, 1998). On the other islands in the lake, where protection is negligible, the exotic Prosopis chilensis has invaded many areas (Scott 1989). In the elevated mudflats, succulent halophytes, such as Arthrocnemum indicus, Sesuvium portulacastrum, Salicornia brachiata, Suaeda maritima, S. monoica and S. nudiflora occur. Submerged macrophytes include species of Enteromorpha, Hypnea, Ulva, Halophila and Enhalus (Oswin 1987).
AVIFAUNA: Pulicat Lake is an extremely important area for a variety of resident and Palaearctic migratory waterfowl. The lagoon supports significant populations of Spot-billed Pelican Pelecanus philippensis. A total of 88 species of birds has been recorded from Pulicat Bird Sanctuary during a BNHS study (Rao and Mohapatra 1993). During the mid-winter waterfowl count in 1988, 83,000 waterfowl were counted in the Sanctuary. However, during 1991 and 1992, the numbers were 38,722 and 10,902 respectively (Rao and Mohapatra 1993). The abundance of waterfowl fluctuates mainly with the prevailing water regime. This site has been selected as an IBA on the basis of its population of Spot-billed Pelican (Criteria A1) and waterfowl congregation (Criteria A4iii). Pulicat is the major foraging ground of pelicans that breed in Nelapattu Bird Sanctuary, an IBA, less than 20 km away (Manakadan and Kannan 2003). The lagoon in Pulicat Lake is one of the two major wintering grounds in southeast India for shorebirds (Prater et al. 1977). Due to its vastness, only a rough estimate of the wader population is possible (Rao and Mohapatra 1993). Many waders are likely to occur above their 1% geographical population threshold. Therefore this site would qualify for A4i criteria. Most of the waders are distributed over the extensive mudflats along the Sriharikota-Sulurpet road and near Tada in the southwest part of the lagoon. The BNHS has conducted ringing camps in this area, and a notable recovery was that of a Curlew Sandpiper Calidris testacea with a Polish ring. Subsequently, it was found that the bird had been banded in the Arctic Circle region of Russia (Rao and Mohapatra 1993). Taher and Pittie (1989) have prepared a checklist of birds of Andhra Pradesh. During ringing at Pulicat Lake in 1990-91, seven birds were added to the bird list of Andhra Pradesh (Rao and Mohapatra 1994). Interesting among them are the Large Sand Plover Charadrius leschenaultii, Knot Calidris canutus, Eastern Knot C. tenuirostris and Black Tern Chlidonias niger. Pulicat Lake also provides suitable feeding conditions for the two species of flamingos. In October 2002, more than 2,000 Greater Flamingos were seen there.
OTHER KEY FAUNA: The mammalian fauna includes the Jungle Cat Felis chaus, Golden Jackal Canis aureus, Wild Boar Sus scrofa, Small Indian Mongoose Herpestes auropunctatus and Monitor Lizard Varanus bengalensis.
Recently, a dead Leopard Panthera pardus was found, trapped in the slush in the lake. This was the first record of Leopard from Pulicat Lake (Kannan and Manakadan in press).
