It is a vast mangrove forest in the Ganges Delta, formed by the confluence of the Ganges, Brahmaputra, and Meghna rivers, stretching from India’s Hooghly River in West Bengal to Bangladesh’s Baleswar River in Khulna. It serves as a vital storm barrier, shoreline stabilizer and sediment trap, while also providing timber, natural resources, and habitat for diverse aquatic and terrestrial life.
