Save the world's largest mangrove forest - "Sundarbans" - Mongla 4.45

Sundarban is the biggest mangrove forest in the world. Sundarban is in South West part of Bangladesh, in the district of greater Khulna. India shares a bit of the forest with Bangladesh. The total area is about 38,000 square kilo meters. Sundarban is a large block of littoral forests. The beauty lies in its unique natural surrounding. The Sundarbans are a part of the world's largest delta formed by the rivers Ganges, Brahmaputra and Meghna. Thousands of meandering streams, creeks, rivers and estuaries have enhanced its charm. For miles and miles, the lofty treetops form an unbroken canopy, while nearer the ground, works of high and ebb-tide marked on the soil and tree trunks and the many varieties of the natural mangrove forest have much to offer to an inquisitive visitor.

Sundarban is the natural habitat of the world’s famous Royal Bengal Tiger, spotted deer, crocodiles, jungle fowl, wild boar, lizards and many more. Migratory flock of Siberian ducks flying over thousands of sail boats loaded with timber, Golpata, fuel wood, honey, shell and fish further add to the serene natural beauty of the Sundarban.

In general, the northern boundary and new depositions are characterized by Baen (Avicennia marina , A. alba, A. officinalis ) flanked by foreshore grassland of Oryza coarctata (Dhani grass). Baen is gradually replaced by Genwa (Excoecaria agallocha) and then Goran (Ceriops spp.). The southern and eastern associates include Garjan (Rhizophora spp.), Kankra (Bruguiera spp.), and few patches of Sundari (Heritiera fomes) . Hental (Phoenix spp.) forest exists in relatively high land and compact soil. Dhundul (Xylocarpus granatum), Passur (Xylocarpus mekongensis) and Nipa fruticans (Golpata) palm swamps are extremely limited.

Famous spots
The main tourist point is Hiron Point (Nilkamal) for watching tiger, deer, monkey, crocodiles, birds and natural beauty. Katka is for watching deer, tiger, crocodiles, varieties of birds and monkey. Morning and evening symphony of wild fowls. Vast expanse of grassy meadows running from Katka to Kachikhali (Tiger Point) provide opportunities for wild tracking. Tin Kona Island for tiger and deer. Dublar Char (Island) for fishermen. It is a beautiful island where herds of spotted deer are often seen to graze. Here land and water meet in many novel fashions, Wildlife presents many a spectacle. No wonder, you may come across a Royal Bengal Tiger swimming across the streams or the crocodiles basking on the river banks. With the approach of the evening herds of deer make for the darking glades where boisterous monkeys shower Keora leaves from above for sumptuous meal for the former. For the botanist, the lover of nature, the poet and the painter this land provides a variety of wonder for which they all crave.




"The Sundarbans (Bengali: সুন্দরবন Shundorbôn) is the largest single block of tidal halophytic mangrove forest in the world. The name Sundarban can be literally translated as "beautiful jungle" or "beautiful forest" in the Bengali language (Sundar, "beautiful" and bans, "forest" or "jungle"). The name may have been derived from the Sundari trees that are found in Sundarbans in large numbers. Alternatively, it has been proposed that the name is a corruption of Samudraban (Bengali: সমুদ্রবন Shomudrobôn "Sea Forest") or Chandra-bandhe (name of a primitive tribe). But the generally accepted view is the one associated with Sundari trees.

The forest lies at the feet of the Ganges and is spread across areas of Bangladesh and West Bengal, India, forming the seaward fringe of the delta. The seasonally-flooded Sundarbans freshwater swamp forests lie inland from the mangrove forests. The forest covers 10,000 km2 of which about 6,000 are in Bangladesh.[2] It became inscribed as a UNESCO world heritage site in 1997, but while the Bangladeshi and Indian portions constitute the same continuous ecotope, these are separately listed in the UNESCO world heritage list as the Sundarbans and Sundarbans National Park, respectively. The Sundarbans is intersected by a complex network of tidal waterways, mudflats and small islands of salt-tolerant mangrove forests. The area is known for the eponymous Royal Bengal Tiger (Panthera tigris tigris), as well as numerous fauna including species of birds, spotted deer, crocodiles and snakes. It is estimated that there are now 500[citation needed] Bengal tigers and about 30,000 spotted deer in the area. Sundarbans was designated a Ramsar site on May 21, 1992. The fertile soils of the delta have been subject to intensive human use for centuries, and the ecoregion has been mostly converted to intensive agriculture, with few enclaves of forest remaining. The remaining forests, together with the Sundarbans mangroves, are important habitat for the endangered tiger. Additionally, the Sundarbans serves a crucial function as a protective flood barrier for the millions of inhabitants in and around Kolkata (Calcutta) against the result of cyclone activity.


History:
During the Mughal period, local kings leased the forests of the Sundarbans to residents. The legal status of the forests underwent a series of changes, including the distinction of being the first mangrove forest in the world to be brought under scientific management. The area was mapped by the Surveyor General as early as 1764 following soon after proprietary rights were obtained from the Mughal Emperor, Alamgir II, by the East India Company in 1757. Systematic management of this forest tract started in the 1860s after the establishment of a Forest Department in the Province of Bengal, in India.
The first Forest Management Division to have jurisdiction over the Sundarbans was established in 1869. The Sundarbans was declared a reserved forest in 1875-76, under the Forest Act, 1865 (Act VIII of 1865). The first management plan was written for the period 1893-98. In 1875 a large portion of the mangrove forests was declared as reserved forests under the Forest Act, 1865 (Act VIII of 1865). The remaining portions of forests was declared as reserve forest the following year and the forest, which was so far was administered by the civil administration district, was placed under the control of the Forest Department. A Forest Division, which is the basic forest management and administration unit, was created in 1879 with the headquarter in Khulna.
In 1911, it was described as a tract of waste country which had never been surveyed, nor had the census been extended to it. It then stretched for about 165 miles (266 km) from the mouth of the Hugli to the mouth of the Meghna and was bordered inland by the three settled districts of the 24 Parganas, Khulna and Backergunje. The total area (including water) was estimated at 6,526 square miles (16,902 km2). It was a water-logged jungle, in which tigers and other wild beasts abounded. Attempts at reclamation had not been very successful. The characteristic tree was the sundari (Heritiera littoralis), from which the name of the tract had probably been derived. It yields a hard wood, used for building, and for making boats, furniture, etc. The Sundarbans were everywhere intersected by river channels and creeks, some of which afforded water communication between Calcutta and the Brahmaputra Valley, both for steamers and for native boats.

Physiography:
The mangrove-dominated Ganges Delta – the Sundarbans - is a complex ecosystem comprising one of the three largest single tract of mangrove forests of the world. Shared between two neighbouring countries, Bangladesh and India, the larger part (62%)is situated in the southwest corner of Bangladesh. To the south the forest meets the Bay of Bengal; to the east it is bordered by the Baleswar River and to the north there is a sharp interface with intensively cultivated land. The natural drainage in the upstream areas, other than the main river channels, is everywhere impeded by extensive embankments and polders. The Sundarbans was originally measured (about 200 years ago) to be of about 16,700 km². Now it has dwindled to about 1/3 of the original size. The total land area today is 4,143 km² (including exposed sandbars: 42 km²) and the remaining water area of 1,874 km² encompasses rivers, small streams and canals. Rivers in the Sundarbans are meeting places of salt water and freshwater. Thus, it is a region of transition between the freshwater of the rivers originating from the Ganges and the saline water of the Bay of Bengal.

Climate change impact:
The physical development processes along the coast are influenced by a multitude of factors, comprising wave motions, micro and macro-tidal cycles and long shore currents typical to the coastal tract. The shore currents vary greatly along with the monsoon. These are also affected by cyclonic action. Erosion and accretion through these forces maintains varying levels, as yet not properly measured, of physiographic change whilst the mangrove vegetation itself provides a remarkable stability to the entire system. During each monsoon season almost all the Bengal Delta is submerged, much of it for half a year. The sediment of the lower delta plain is primarily advected inland by monsoonal coastal setup and cyclonic events. One of the greatest challenges people living on the Ganges Delta may face in coming years is the threat of rising sea levels caused mostly by subsidence in the region and partly by climate change. The average maximum and minimum temperature is 34 °C and 20 °C respectively. Rainfall is heavy with high humidity as high as 80% as it is close to the Bay of Bengal. The monsoon lasts from mid-June to mid-September. Prevailing wind is from the north and north-east from October to mid-March and south west westerlies prevails from mid-March to September. Storms which sometimes develop into cyclones are common during the month of May and October.

Economy:
The Sundarbans has a population of over 4 million but much of it is mostly free of permanent human habitation. The Sundarbans play an important role in the economy of the southwestern region of Bangladesh as well as in the national economy. It is the single largest source of forest produce in the country. The forest provides raw material for wood based industries. In addition to traditional forest produce like timber, fuelwood, pulpwood etc., large scale harvest of non wood forest products such as thatching materials, honey, bees-wax, fish, crustacean and mollusk resources of the forest takes place regularly. The vegetated tidal lands of the Sundarbans also function as an essential habitat, nutrient producer, water purifier, nutrient and sediment trap, storm barrier, shore stabilizer, energy storage unit and aesthetic attraction.

Tourist attraction in Sundarban:
Moving through the largest estuarine delta in the world is quite a thrilling experience. The flora and fauna of the region are the major attractions here. The mangrove forest presents a unique ecosystem. The wildlife includes the world famous Royal Bengal Tiger, a major attraction in the tiger reserve. Some of the other attractions include chital, crocodile, monkeys, estuarine and marine turtle, dolphins and various kinds of birds. The Bhagabatpur Crocodile Project besides being a hatchery and a sanctuary is the home to the biggest estuarine crocodiles."
