Abstract: The coastal regions are most suitable for biodiversity, because it acts as the interlink between ocean and land biomass. The sustain ecosystem in the coastal region is most important condition to have a stable ecological succession in its neighbour habitats. The coastal belt is about 14km length from the Orissa border to Jaldha mouja, situated between 213650N to 2141 59.52N and 872940E to 873700E in the district of Purba Medinipur of Westbengal, India, and it is well known as Digha coast. It is a hot spot for biodiversity. As well as a very popular coastal tourist spot in the North East India. Almost every days of the year it is crowded by domestic and international tourists. The newly taken government plans is increasing its importance of tourist. In the respect the construction of resorts, lodges, roads, shopingmals, parking zones, the used and rejected materials by the tourists etc. Are gradually affecting the coastal ecosystem, both Geomorphologic ally and culturally as well environmental. In my present work it is found that different flora and fauna species are in great trouble, some are going to be abolished, some are finished. The environmental balance or equilibrium and biological balance have been lost. This in turn is destroying the natural beauty. This was the main reason for it to become a tourist spot. In the present work both primary and secondary data have been collected by me. The thematic map technique, cartographic technique and statistical methods are used to interpret the collected data. The founding is very significant to make decision to create a eco-friendly situation in spite of the development of tourism in this site.
