Sundarbans freshwater swamp forests

This almost extinct ecoregion, intensely exploited, cultivated and built over with dense human populations is in the vast delta formed by the confluence of several of South Asia’s largest rivers. It includes swamp forests surrounding the Sundarbans Mangroves, in the zone where the freshwater from the rivers push back the saline waters of the intruding ocean. This ecoregion also straddles the political boundary between Bangladesh and India’s state of West Bengal. Forest and habitat loss are so extensive that it is difficult to ascertain the composition of the original vegetation of this ecoregion. Historical records suggest that the forests used to have mangrove tree species of Heritiera, Xylocarpus, Bruguiera, Avicennia, and Sonneratia.
