Site description Tiruchirappalli district of Tamil Nadu has a large number of irrigation reservoirs, fed by the River Kaveri and by rainwater. Karaivetti is one such lake, about 50 km northeast of Tiruchchirappalli town. This freshwater lake is fed by Pullambadi, Kattalal canal. It is the biggest waterbody in the district and attracts hundreds of thousands of birds every year. Considering its importance as a bird habitat, the Government of Tamil Nadu declared it as a bird sanctuary in 1999. When full, the lake can hold water to an average depth of 3 m (Anon. 1993). From April to August, the water level is low. In the northern dry part of the lake, cotton, castor, maize, gram and coriander are cultivated annually, while in the wetter southern part, paddy and sugarcane are cultivated. The natural and planted vegetation consist of Acacia nilotica, Prosopis chilensis, Azadirachta indica and Tamarindus indica. The Acacia nilotica plantation is the major nesting site for birds. In the wetland, Typha angustata and Fimbristylis sp. are present. Ipomea aquatica grows as a weed in many parts of the reservoir. Floating and partly submerged plants include Elodea, Hydrilla, Salvinia and Spirodella sp.
