UNESCO has decleared the Sundarbans a world Heritage site.

The Sundarban is the largest  mangrove forest in the world. The forests aren't also just mangrove swamps but also  include some of the last remaining stands of the mighty jungles which once covered the Gangetic plain. The Sundarban covers an area of 38,500 sq km, of which about one-third is covered in water. Since 1966 the Sundarban has been a wildlife sanctuary.It lies on the Ganges-Brahmaputra Delta at the point where it merges with the Bay of Bengal . The forest lies a little south to the Tropic of Cancer between the latitudes 21º30´N and 22º30´N, and longitudes 89º00´E and 89º55´E.The Bangla word ban means forest, and the name Sundarban was coined either from the forests of Sundari tree ie Sundari-ban, or from the forests of the samudra (sea) ie, Samudra-ban, or from its association with the primitive tribe Chandra-bandhe which was corrupted into Sundarban. The generally accepted explanation, however, is its derivation from the Sundari tree, the most common tree in these forests.

Sundarban is the home to many different species of birds, mammals, insects, reptiles and fishes. Over 120 species of fishes and over 260 species of birds have been recorded in the Sundarban. The Gangetic River Dolphin  is common in the rivers. The Sundarban now supports the only population of the Estuarine, or Salt-Water Crocodile (Crocodylus parasus) in Bangladesh.Its beauty lies in its unique natural surrounding. Sundarban is the natural habitat of the world famous Royal Bengal Tiger, spotted deer, crocodiles, jungle fowl, wild boar, lizards, theses monkey and an innumerable variety of beautiful birds. Migratory flock of Siberian ducks flying over thousands of sail boats loaded with timber, golpatta (round-leaf), fuel wood, honey, shell and fish further add to the serene natural beauty of the Sundarban.
