Wetlands in India are distributed in different geographical regions ranging from Himalayas to Deccan plateau. The variability in climatic conditions and changing topography is responsible for significant diversity. Coastal wetlands include littoral zones, brackish water and estuarine regions, lagoons and coral reefs, and constitute ~ 70% of total wetlands of the country. The Ramsar Convention is an intergovernmental treaty, which provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources. In the present study, an attempt has been made to highlight the diverse floral resources and distribution of vegetation types in wetlands of Point Calimere, Nagapattinam District, Tamil Nadu. Exploratory surveys involving field visits and literature review were carried out to find out the present status of wetlands during 2008 – 2009. About 147 plant species of 110 genera belonging to 55 families are described.
