Some believe that the name Sundarbans is derived from 'Sundri' - a plant found in the local mangroves - and 'bans' meaning forest. Others believe the name means 'beautiful forest' ('sunder' = beautiful, and 'bans' = forest). The Sundarbans, extending over an area of 1,000,000 hectares, is the world's largest delta, formed by the Ganges, Brahmaputra and Meghana rivers. The region has extensive mangrove forests and the contours are in a constant state of flux, caused by the monsoon flooding each year. Roughly a third of the delta is water, consisting of rivers, channels and tidal creeks up to 5 kilometers wide. The Sundarbans falls both within the India and Bangladesh, the latter having the larger share of the delta. On the Indian side there is a national park overlooking the Bay of Bengal.
The Sundarbans West, South and East wildlife sanctuaries in Bangladesh are also at the southern extremities of the delta. The Sundarbans parks are covered in mangrove forests of which there are 3 main zones, depending on the level of salt in the soil and water a freshwater zone, a moderately saline zone, and a saline zone. Fishing, timber extraction and honey collection are the main human activities allowed within the Sundarbans. The four Sundarbans national parks have been lumped together as they all share common features of the estuarine mangrove ecosystem. The main attractions of the Sundarbans are the Tiger, of which the delta harbor large reptiles like the Monitor Lizard, Estuarine Crocodile and the Olive Ridley Turtle, for which there is a conservation programme in the Indian park. The Leopard, Indian Rhinoceros, Javan Rhinoceros, Swamp Deer, Hog Deer and Water Buffalo have all become locally extinct from the delta in recent decades.
