Site description (2004 baseline)
This irrigation tank is a small dam built across the Gundal river, a tributary of the Kabini (Kapila) river, 5 km from the temple town of Nanjangud, which is situated 20 km south of Mysore city. It is a fairly important irrigation tank in Mysore district in terms of both waterspread and the irrigated area. The tank is surrounded by coconut plantations, an Acacia plantation of the Forest Department, paddy fields and the Tagadur Ramachandra Rao canal (Kabini dam right bank canal).
Key biodiversity
AVIFAUNA: The IBA is an important congregation site for the Bar-headed Goose Anser indicus, Spot-billed Pelican Pelecanus philippensis, Black-headed or White Ibis Threskiornis melanocephalus and Glossy Ibis Plegadis falcinellus, and a winter home to the globally threatened Greater Spotted Eagle Aquila clanga. Nearly 750 Bar-headed Geese (1% threshold is 560; Wetlands International 2002), over 2,000 Glossy Ibis (1% threshold is 250), 700 Black-headed Ibis (1% threshold is 100), and 200 Spot-billed Pelican (1% threshold is 40) winter in this lake, along with one or two individuals of the Greater Spotted Eagle. Large numbers of waders and ducks, especially the Northern Pintail Anas acuta and Common Pochard Aythya ferina when the water is deeper, and Garganey Anas querquedula and Northern Shoveller Anas clypeata when the water is shallow, also occur in winter. This IBA is a very rich birding area, where over 100 species can easily be recorded on a three-hour morning visit in winter (T. Shivanand pers. comm. 2003). This site easily fulfils A1 and A4i criteria for IBA selection, developed by BirdLife International (undated).
OTHER KEY FAUNA: As this artificial water body is surrounded by human habitation and cultivation, no large wild mammal is found here. No information is available on reptiles, amphibians or fish fauna.
