Environmental Hazards and Conservation Approach to the Biodiversity and Ecosystem of the St. Martin’s Island in Bangladesh

St. Martin’s Island, a unique island of Bangladesh, is of high ecological significance as it is the only island in Bangladesh that has coral colonies in the shallows including large areas of sand dunes and mangrove formations (Tomascik 1997). It is recognized as one of the richest biodiversity hotspot in terms of marine biotic resources, unparallel in the country. The island is endowed with vast marine and land resources having global biodiversity significance. The island is a good example of co-occurrence of corals, algae, sea weeds, grasses and mangroves (UNDP 2010). Besides the ecological importance St Martin’s is one of the most attractive tourist spots in Bangladesh because of its panoramic landscapes, clear sea water, and natural treasures of coral colonies.
