The Sundarbans (Bengali: সুন্দরবন, Shundorbon) is a natural region in Bengal. It is the largest single block of tidal halophyticmangrove forest in the world. The Sundarbans covers approximately 10,000 square kilometres (3,900 sq mi) of which 60 percent is in Bangladesh with the remainder in India. The Sundarbans is a UNESCO World Heritage Site. The Sundarbans National Park is a National Park, Tiger Reserve, and a Biosphere Reserve located in the Sundarbans delta in the Indian state of West Bengal. Sundarbans South, East and West are three protected forests in Bangladesh. This region is densely covered by mangrove forests, and is one of the largest reserves for the Bengal tiger.
Sundarban National Park:
The Sundarban National Park is a National Park, Tiger Reserve, and a Biosphere Reserve in West Bengal, India. It is part of the Sundarbans on the Ganges Delta, and adjacent to the Sundarbans Reserve Forest in Bangladesh. The delta is densely covered by mangrove forests, and is one of the largest reserves for the Bengal tiger. It is also home to a variety of bird, reptile and invertebrate species, including the salt-water crocodile. The present Sundarbans National Park was declared as the core area of Sundarbans Tiger Reserve in 1973 and a wildlife sanctuary in 1977. On 4 May 1984 it was declared a National Park.
Sundarbans West Wildlife Sanctuary:
Sundarbans West Wildlife Sanctuary is a UNESCO World Heritage Site. The region supports several mangroves, including sparse stands of Gewa (Excoecaria agallocha) and dense stands of Goran (Ceriops tagal), with discontinuous patches of Hantal palm (Phoenix paludosa) on drier ground, river banks and levees. The fauna of the sanctuary is very diverse with some 40 species of mammals, 260 species of birds and 35 species of reptiles. The greatest of these being the Bengal Tiger of which an estimated 350 remain in the Bangladesh Sundarbans. Other large mammals are wild boar, Chital horin (spotted deer), Indian otter and macaque monkey. Five species of marine turtles frequent the coastal zone and two endangered reptiles are present – the estuarine crocodile and the Indian python.
Sundarbans East Wildlife Sanctuary:
Sundarbans East Wildlife Sanctuary extends over an area of 31,227 hectares (77,160 acres). Sundari trees (Heritiera fomes) dominate the flora, interspersed with Gewa (Excoecaria agallocha) and Passur (Xylocarpus mekongensis) with Kankra (Bruguiera gymnorrhiza) occurring in areas subject to more frequent flooding. There is an understory of Shingra (Cynometra ramiflora) where, soils are drier and Amur (Aglaia cucullata) in wetter areas and Goran (Ceriops decandra) in more saline places. Nypa palm (Nypa fruticans) is widespread along drainage lines.
Sundarbans South Wildlife Sanctuary:
Sundarbans South Wildlife Sanctuary extends over an area of 36,970 hectares (91,400 acres). There is evidently the greatest seasonal variation in salinity levels and possibly represents an area of relatively longer duration of moderate salinity where Gewa (Excoecaria agallocha) is the dominant woody species. It is often mixed with Sundri, which is able to displace in circumstances such as artificially opened canopies where Sundri does not regenerate as effectively. It is also frequently associated with a dense understory of Goran (Ceriops tagal) and sometimes Passur.
Sajnakhali Wildlife Sanctuary:
Sajnakhali Wildlife Sanctuary is a 362-square-kilometre (140 sq mi) area in the northern part of the Sundarbans delta in South 24 Parganas district, West Bengal, India. The area is mainly mangrove scrub, forest and swamp. It was set up as a sanctuary in 1976. It is home to a rich population of different species of wildlife, such as water fowl, heron,pelican, spotted deer, Rhesus Macaques, wild boar, tigers, Water Monitor Lizards, Fishing Cats, otters, Olive ridley turtle, crocodiles, Batagur Terrapins, and migratory birds.
Habitation:
The Sundarbans has a population of over 4 million but much of it is mostly free of permanent human habitation. Despite human habitations and a century of economic exploitation of the forest well into the late forties, the Sundarbans retained a forest closure of about 70% according to the Overseas Development Administration (ODA) of the United Kingdom in 1979.
Administration:
The Sundarbans area is one of the most densely populated in the world, and the population is increasing. As a result, half of this ecoregion's mangrove forests have been cut down to supply fuelwood and other natural resources. Despite the intense and large-scale exploitation, this still is one of the largest contiguous areas of mangroves in the world. Another threat comes from deforestation and water diversion from the rivers inland, which causes far more silt to be brought to the estuary, clogging up the waterways.
The Directorate of Forest is responsible for the administration and management of Sundarban National Park in West Bengal. The Principal Chief Conservator of Forests (PCCF), Wildlife & Bio-Diversity & ex-officio Chief Wildlife Warden, West Bengal is the senior most executive officer looking over the administration of the park. The Chief Conservator of Forests (South) & Director, Sundarban Biosphere Reserve is the administrative head of the park at the local level and is assisted by a Deputy Field Director and an Assistant Field Director. The park area is divided into two ranges, overseen by range forest officers. Each range is further sub-divided into beats. The park also has floating watch stations and camps to protect the property from poachers.
The park receives financial aid from the State Government as well as the Ministry of Environment and Forests under various Plan and Non-Plan Budgets. Additional funding is received under the Project Tiger from the Central Government. In 2001, a grant of US$20,000 was received as a preparatory assistance for promotion between India and Bangladesh from the World Heritage Fund.
A new Khulna Forest Circle was created in Bangladesh back in 1993 to preserve the forest, and Chief Conservators of Forests have been posted since. The direct administrative head of the Division is the Divisional Forest Officer, based at Khulna, who has a number of professional, subprofessional and support staff and logistic supports for the implementation of necessary management and administrative activities. The basic unit of management is the compartment. There are 55 compartments in four Forest Ranges and these are clearly demarcated mainly by natural features such as rivers, canals and creeks.
Protection:
The Bangladesh part of the forest lies under two forest divisions, and four administrative ranges viz Chandpai (Khulna District),Sarankhola (Khulna), and Burigoalini (Satkhira District) and has sixteen forest stations. It is further divided into fifty-five compartments and nine blocks. There are three wildlife sanctuaries established in 1977 under the Bangladesh Wildlife (Preservation) Order, 1973 (P.O. 23 of 1973).The West Bengal part of the forest lies under the district of South & North 24 Parganas.
Protected areas cover 15% of the Sundarbans mangroves including Sundarbans National Park and Sajnakhali Wildlife Sanctuary, inWest Bengal, Sundarbans East, Sundarbans South and Sundarbans West Wildlife Sanctuaries in Bangladesh.
