The Bay of Bengal is an area of high biodiversity, with many endangered and vulnerable species. The major transboundary issues relating to habitats are: the loss and degradation of mangrove habitats; degradation of coral reefs; and the loss of, and damage to, seagrasses. The transboundary nature of these major issues are: that all three critical habitats occur in all BOBLME countries. Coastal development for several varying uses of the land and sea are common in all BOBLME countries. Trade in products from all the habitats is transboundary in nature. Climate change impacts are shared by all BOBLME countries.
