India is a rich biodiversity area. But our climate is changing continuously, therefore research and review of our precious ecosystem is necessary. Sirpur wetland is a freshwater ecosystem in Indore, M.P. It is important as 130 species of migratory and native bird’s dependent on the site for their habitat. Recently it is declared Ramsar site. One more pride of Indore city. Therefore, its conservation is our duty. Sirpur wetland provides important ecological services like source of water, fisheries, cultivation of medicinal plants, buffering communities which protect from floods and storm and helps to recharge ground water. Anthropogenic pressure on wetland led to direct impact on species diversity, population and quality of water. Comparative study of physicochemical parameters of Sirpur wetland done to find that these parameters are under permissible limit or not. The water is becoming eutrophic over a period of time and affecting macrophytes communities. The study of fresh water Bivalves Lamellidens corrianus inhabiting in Sirpur Lake of Indore used to determine a local environmental monitoring network and act as a bio-indicator to determine bioaccumulation of heavy metals (Zn, Cu, Pd, Cd) in freshwater ecosystem. And reaches from primary producers to humans through food web. There is a change in species composition of Lake also, Growth of highly invasive species (Eichhornia crassipes and Pistia stratiote etc.) in lake is a matter of concern. Plants absorbs these heavy metals and nutrients above their permissible limit and shows massive growth. These invasive species with massive growth reduces the growth of other species and algae. But simultaneously, they act as a water purifier by absorbing toxic substances like metal ions, organic and inorganic substances. But they need to be harvest regularly before they start to destroy other aquatic organisms like fish and some invertebrates. When they died, their decomposition releases nutrients into the water and disturbs food web and nutrient cycling. They have some beneficial uses along with harmful effects. Some studies shows that these plants may use to prepare ethanol by fermenting them. Crude extract of E, crassipes shows anticancer activity over several tumour type. Preparation of biogas by bio methanation of mixture of E. crassipes, Garden waste, Food waste and Municipal solid waste in different proportion. Sludge obtained from digester used to form fuel pellets and vermicompost. Our conclusion by this review suggested need of regular monitoring of lake water and harvesting of invasive species (E. crassipes) followed by using it as a useful product.
