National Wetland Conservation Programme, Revised Guidelines

Wetlands, natural and manmade, freshwater or brackish, provide numerous ecological services. The density of birds, in particular, is an accurate indication of the ecological health of a particular wetland. However, unsustainable use of wetlands without reckoning of their assimilative capacity constitutes major threat to the conservation and management of these vital biodiversity rich areas. Thus, restricting the prospects of future generation to utilize the benefits of the ecosystem services provided by these wetlands.
