wetlands in India

Wetlands in India are areas where water is the primary factor controlling the environment and the associated plant and animal life.

They occur where the water table is at or near the surface of the land, or where the land is covered by water. Once treated as transitional habitats or seral stages in succession from open water to land, the wetlands are now considered to be distinct ecosystems with specific ecological characteristics, functions and values.

Wetlands in India is very rich in wetland habitats exhibiting different ecological diversities, climatic conditions and changing topography.

A great number of these wetland habitats have been affected by various human impacts but realising the crucial role of the wetlands in ground water recharge, ground water discharge, flood storage and desynchronization, shoreline anchoring and dissipation of erosive forces, sediment traping, nutrient retention and removal, food chain support, habitat for fisheries, habitat for wild life, active recreation, passive recreation and heritage value.

Wetlands in India On the basis of topographical variation, Indian Wetlands are of four major types-

1) Himalayan Wetlands

2) Wetlands in the Gangetic plain

3) Wetlands in the desert

4) Coastal Wetlands.

Along the 7,500 km coast line of India, there is a great diversity of wetland habitat with lagoons, estuaries, mangrove swamps and coral reefs.

Among the coastal wetlands, coastal lagoons are the shallow coastal water bodies separated from the ocean by a barrier connected at least intermittently to the ocean by one or more restricted inlets and usually oriented parallel to shore

Coastal lagoons are usually found on low-lying coasts and are normally aligned with their largest diameter parallel to the seashore.  A number of lagoons are distributed all along the East and the West Coasts of India.  There are 17 noteworthy lagoons in Indian coast with 8 on the east and 9 on the west.
