Subsequently, the surrounding 5 km (3.1 mi) zone were declared as part of the sanctuary as per the Wildlife Protection Act, 1972 in 1996 and the final notification was issued on 8 July 1998.

[2][8] The sanctuary consists of many small water bodies interconnected with the main tank, located at an altitude of about 122 m (400 ft).

[11] The sanctuary consists of a mixture of tropical and sub-tropical dry broadleaf forests interspersed with thorns and shrubs.

[1][2] The wetland and the surrounding areas have been subject to deforestation and over grazing from domestic livestock, which resulted in the stunted scrub vegetation.

The Barringtonia trees also serve as roosts for the non-breeding birds and safe high perches for the young lings.

There are other species such as Acacia nilotica, Alangium salviifolium, Albizzia lebbek, Azadirachta indica, Morinda tinctoria, Borassus flabellifer, Cassia fistula, and Solanum trilobatum on the area surrounding the tank.

The partly submerged scrubs around the tank provides twigs for the birds to build nests and also serve as roosting grounds.

There are also reptiles and amphibians such as water snakes, Indian cobra, sand boas, terrapins, tortoises, lizards, and frogs.
