Abstract
The present study was to assess the anthropogenic pressure on Samudram Lake, Thanjavur, with special reference to Water study, Biodiversity study and their sustainability. The lake has only a thin film of plankton and low rate of productivity. The nutrient status of the lake was negligible but the potassium content of the lake water increased when compared with the previous studies. The species diversity indices, abundance and lake potential were assessed based on the data obtained during the study period. Immediate corrective measures are needed to ensure ecological sustainability by way of integrated management, development and conservation of this important wetland ecosystem. Because the Lake, which is the main source of agricultural practices, is under serious threat due to sedimentation, siltation and pollution affecting the whole aquatic environment and consequently the unique biodiversity, land and people. This shows the silting and land erosion from the catchment area since the lake is an enclosed water body. Conservation strategies were also suggested to prevent the lake from further deterioration and finally the lake will turn to waste or barren land.
