The mangrove ecosystem has been identified as very unique but fragile, dynamic and most productive as any other ecosystem. Increasing human pressure on the limited mangrove resources due to increase in population. Increasing awareness regarding environmental and economic use of mangroves has highlighted the need for mangrove conservation and management. In India, mangroves occur on the West Coast, on the East Coast and on Andaman and Nicobar Islands, but in many places they are highly degraded. According to the Government of India (1987), India lost 40% of its mangrove area in the last century. The National Remote Sensing Agency (NRSA) recorded a decline of 7000 ha of mangroves in India within the six-year period from 1975-1981. Increasing human population in coastal areas is resulting in increased pressure on mangrove ecosystems in many countries, with the growing demand for timber, fuel wood, fodder and other non-wood forest products.
