BIODIVERSITY VALUES
Flora: More than 450 plant species have been
recorded. Aquatic plants with unique physiological adaptation are Water
Primrose (Ludwigia alscendens) and Bladderwort (Utricularia
australis). Biogeographically important as representatives of the Indo
Malayan realm are Sal (Shorea robusta) and Myrobalan (Terminalia
alata). Threatened plant species include the endangered Orchid (Aerides
odorata), religiously important and threatened Lotus (Nelumbo nucifera),
and rare wild rice (Hygrohiza aristata).
Fauna: The fauna comprises lower risk species on
the IUCN Red List like Ferruginous Duck (Aythya nyroca), Grey-headed
fish eagle (Ichthyophaga ichthyaetus), and Asiatic Rock Python (Python
molurus). Further rare species include the lizard (Varanus flavescens).
In total 29 fish species have been recorded including the threatened Puntius chola and the endemics Notopterus notopterus and Oxygaster bacaila. Around 140 partly migrating bird species inhabit the area representing over16% of the national avifauna. Nearly 1% of the South Asian Cotton Teal (Nettapus coromandelianus) population is present.
The floating vegetation provides an excellent habitat for waterhen and jacanas; the surrounding forest for birds of prey (e.g. the rare osprey many globally threatened species (IUCN, 2002) such as the critically endangered Red-crowned Roofed Turtle (Kachuga kachuga), the endangered Tiger (Pantheratigris), Leopard (Panthera pardus), and Three-striped Roof Turtle (Kachuga dhongka), and the vulnerable Smooth-coated Otter (Lutra perpiscillata), Common Otter (Lutra lutra), Lesser Adjutant Stork (Leptotilos javanicus) and Marsh Crocodile (Crocodylus palustris).
The forest is used for grazing, fuel wood and to
harvest sal wood for timber. The lake has high potential value for tourism.
