Abstract :

The state West Bengal comprises a good number of floodplain wetlands. These wetlands possess a unique type of ecosystem and play a vital role in maintenance of socio economic condition of concerned area. A yearlong study was conducted in two wetlands of the state West Bengal viz., Hansadangabeel of district Nadia and Purbasthalibeel of district Burdwan to analyse the nutrient status of sediment and their role in Net and Gross primary productivity. The present study recorded comparatively high primary productivity in Hansadangabeel (L1) than Purbasthalibeel (L2) due to its high range of nutrient status. Furthermore, due to rapid urbanisation and various anthropogenic entries the overall nutrient status of these wetlands is being disturbed. So a proper management approach is needed to conserve these unique ecosystems through their rich nutrient status
