This wetland on the Deccan Plateau is an endorheic or closed basin, almost circular in shape, formed by a meteorite impact onto the basalt bedrock. The Site includes the lake as well as escarpments, which form the crater walls, and forested zones. The lake is high in salinity and alkalinity, as the lack of an outflow leads to a concentration of minerals as the lake water evaporates. Specialized micro-organisms such as anaerobes, cyanobacteria and phytoplankton survive in this harsh chemical environment. Outside the lake, there is considerable diversity of plant and animal life, as springs which help feed the lake provide a source of fresh water. Inhabiting the Site are 160 species of birds including the vulnerable Asian woollyneck (Ciconia episcopus) and common pochard (Aythya ferina), 46 species of reptiles, and 12 species of mammals including the iconic grey wolf (Canis lupus). Factors which threaten the site include household sewage and urban wastewater, and unsustainable tourism.
Site lies in Buldhana district in the state of Maharashtra
