ABSTRACT- While the forests and green cover are regarded as lungs of nature, wetlands are regarded as kidney of nature. Despite their great importance, wetlands are worst sufferers in recent years due to effluent and sewage discharge, solid waste disposal, land-fill activities to extend agriculture or house buildings etc. Wetlands are of multiple uses, both conventional for fish domestic and irrigation water to otherwise less conventional as site of worship, religious congregations and cremation of dead bodies, seasonal as well as perennial rivers like Ganga, Son, Gandak drain this most densely populated state. Our studies on lentic wetlands of Aurangabad district in rural, rather quiet and unpolluted to urban highly disturbed, polluted by city garbage encroachment, over exploitation of fishes and water chestnut (Trapa bispinosa) for its edible fruit and starchy flour have been carried out for biodiversity of plants, animal and planktonic forms and ecology like water chemistry, food chain etc. The rural ponds rich in different species of self grown lilies and lotus (Nymphaea spp. Nelumbium Spp.), Hydrilla sp. Naja sp. Vellisneria sp. are dominant. Maximum diversity and phytomass is recorded in emergent vegetation marginal marshy areas dominated by Eleocharis, Cyperus, Polygonum, Typha etc. For founal biodiversity, the common fishes recorded are Rohu (Labeo rohita), Singhi (Heteropneustes fossilis), Katla (Catla catla), Mangur (Clarias batrachus), Boari (Wallgo attu) and for Zooplanktons Daphnia, Cyclop Zoaea, Nauplius Hirudinaria, Unio, amphibians like Rana tigrina etc. Seasonas play Important-controlling force in periodicity occurrence and population size.
