ABSTRACT:
Rajasthan is the largest State of India constituting 10.4% of country's geographical area. The State is poor in water resources. However, 40 % of the country's Avifauna has been reported from this State out of which about two-fifth species are dependent on wetlands or opportunistically exploit wetlands. A survey of about 40 lakes of six districts of Eastern Rajasthan, which receives moderate rainfall (between 60-70 cm annually), was carried out during 2004-2006. The study area falls in semi-arid bio-geographical province (4A and 4B) of India. This area has got one of two Ramsar sites of Rajasthan, two national parks and 7 Wildlife Sanctuaries and comprises about 9% geographical area of the State.
The study was conducted to prepare an inventory of all major wetlands of the region; find out avian bio-diversity of lakes of the region and to record status of aquatic vegetation, weed-infestation, and use of lakes by local communities. Occurrence of some other indicator or important aquatic species, such as sponges, crabs, mollusks, crocodile, otters was also recorded.
The study revealed that the lakes in the region were relatively free from weed-infestation and point source pollution but were overexploited for fishery operations and irrigation. Majority of the lakes are man-made or man-modified lakes. Nearly all lakes get fully dried up at least once in 4-5 years. The representation of characteristic and specialized wetland/aquatic species or species that prefer specific aquatic micro-habitat, such as otters, fishing cat, storks, curlew, avocet, bitterns, rails, snipes, blue-throat, was very poor. None of the lake was found occupied by otters. Only 3 had a species of sponge.
The study also recommends certain landscaping measures to enhance species richness of these lakes.
