Site description Alniya is an irrigation tank that supports agriculture in the surrounding areas through minor and major canals. Many pairs of Sarus Crane Grus antigone use the habitat around the lake for breeding. In February 2002, Manoj Kulshreshtha, State Coordinator of IBCN, conducted a survey. He found 20-21,000 waterfowl in the lake, and 16 pairs of Sarus raising their chicks. Due to scanty rainfall in 2002, this lake was affected and reduced to one-fourth of its total capacity. With normal rainfall and consequently normal waterspread, there could be 30,000 waterfowl here. This is identified as an IBA on the basis of the large number of waterfowl that gather in this wetland in winter. No proper floral study has been conducted in this wetland. Common plants found in the waterbody were Ceratophyllum muricatum, Eichhornia crassipes, Ipomoea aquatica, Lemna aequinoctalis, Phragmites karka, Polygonum glabrum, Potamogeton pectinatus and Vallisneria spiralis.
