Mangroves in India account for about 5 per cent of the world's mangrove vegetation and are spread over an area of about 4,500 km 2 along the coastal States/UTs of the country. There have been significant changes in the traditional and present uses of resources within the mangrove system, which have implications on its depletion. Various studies showed that mangrove vegetation cover only 1,095 ha in Kerala (Kurien, et al., 1994). Natural regeneration in underutilized lands in backwater systems, afforestation programmes, conservation initiatives and growing awareness on the mangrove ecosystems have highlighted the need to conserve and manage them sustainably. 1999.
