The Bengal tiger is a population of the Panthera tigris tigris subspecies and the nominate tiger subspecies. It ranks among the biggest wild cats alive today. It is considered to belong to the world's charismatic megafauna.
The Ganges Delta is a river delta in Eastern South Asia predominantly covering the Bengal region of the subcontinent, consisting of Bangladesh and the Indian state of West Bengal. It is the world's largest river delta and it empties into the Bay of Bengal with the combined waters of several river systems, mainly those of the Brahmaputra River and the Ganges River. It is also one of the most fertile regions in the world, thus earning the nickname the Green Delta. The delta stretches from the Hooghly River east as far as the Meghna River.
Sundarbans is a mangrove area in the delta formed by the confluence of the Ganges, Brahmaputra and Meghna Rivers in the Bay of Bengal. Spread across parts of India and Bangladesh, this forest is the largest mangrove forest in the world. It spans the area from the Baleswar River in Bangladesh's division of Khulna to the Hooghly River in India's state of West Bengal. It comprises closed and open mangrove forests, land used for agricultural purpose, mudflats and barren land, and is intersected by multiple tidal streams and channels. Sundarbans is home to the world's largest area of mangrove forests. Four protected areas in the Sundarbans are enlisted as UNESCO World Heritage Sites, viz. Sundarbans West (Bangladesh), Sundarbans South (Bangladesh), Sundarbans East (Bangladesh) and Sundarbans National Park (India).
Lohachara Island was an islet which was permanently flooded in the 1980s. It was located in the Hooghly River as part of the Sundarban delta in the Sundarban National Park, located near the Indian state of West Bengal. The definite disappearance of the island was reported by Indian researchers in December 2006, which led to international press coverage. No specific study was ever done to prove that the island was permanently inundated because of sea level rise.
Gosaba is a village and a gram panchayat within the jurisdiction of the Gosaba police station in the Gosaba CD block in the Canning subdivision of the South 24 Parganas district in the Indian state of West Bengal.
Sundarbans usually refers to the Sundarbans' freshwater swamp forests, the term applying generally to a tropical moist broadleaf forest ecoregion of Bangladesh and India. It may specifically refer to:
Tiger attacks in the Sundarbans, in India and Bangladesh are estimated to kill from 0-50 people per year. The Sundarbans is home to over 100 Bengal tigers, one of the largest single populations of tigers in one area. Before modern times, Sundarbans tigers were said to "regularly kill fifty or sixty people a year".
Thakuran River is a tidal estuarine river that forms a wide estuary in and around the Sundarbans in South 24 Parganas district in the Indian state of West Bengal.
Global mangrove distributions have fluctuated throughout human and geological history. The area covered by mangroves is influenced by a complex interaction between land position, rainfall hydrology, sea level, sedimentation, subsidence, storms and pest-predator relationships). In the last 50 years, human activities have strongly affected mangrove distributions, resulting in declines or expansions of worldwide mangrove area. Mangroves provide several important ecological services including coastal stabilization, juvenile fish habitats, and the filtration of sediment and nutrients). Mangrove loss has important implications for coastal ecological systems and human communities are dependent on healthy mangrove ecosystems. This article presents an overview of global mangrove forest biome trends in mangrove ecoregions distribution, as well as the cause of such changes.
Sundarbans East Wildlife Sanctuary, a protected forest in Bangladesh, extends over an area of 31,227 ha. of mangrove forest. It was established in 1977 under the Bangladesh Wildlife (Preservation) (Amendment) Act, 1974, having previously been a forest reserve. It is the most fertile of the three, non-adjoining wildlife sanctuaries established in the Sundarbans at that time, the others being the Sundarbans West Wildlife Sanctuary and the Sundarbans South Wildlife Sanctuary. The dominant mangrove species is "sundri" from which the Sundarbans region gets its name.
Sundarbans South Wildlife Sanctuary is a reserve forest in Bangladesh that extends over an area of 36,970 hectares of mangrove forest. It is situated next to the Sundarbans National Park in West Bengal, India. The sanctuary is one of three Sundarbans wildlife sanctuaries, the others being the Sundarbans East Wildlife Sanctuary and the Sundarbans West Wildlife Sanctuary.
Sundarbans West Wildlife Sanctuary is a UNESCO World Heritage Site and animal sanctuary in Bangladesh. The area of the reserve covers 715 km2. It is part of the larger Sundarbans region, one of the largest mangroveforests in the world. It is formed at the unified delta of the Ganges, Brahmaputra and Meghna rivers on the Bay of Bengal. The total area of the entire Sundarbans is about one million ha, 60% of which is found in Bangladesh, with the remainder 40% in India. The region is divided by the Raimangal River. Within the Bangladeshi area of Sundarbans, there are three wildlife sanctuaries: Sundarbans East, Sundarbans South, and Sundarbans West.
Three species of crocodilian are present in India. The mugger crocodile is found in lakes and rivers throughout the country. The saltwater crocodile is found along the eastern coast of the country and the Nicobar and Andaman Islands. The gharial is found in river areas, though is greatly reduced from its previous range. In the pre-historic period, seven species resided in India.
The 2014 Sundarbans oil spill was an oil spill that occurred on 9 December 2014 at the Shela River in Sundarbans, Bangladesh, a UNESCO World Heritage Site. The spill occurred when an oil-tanker named Southern Star VII, carrying 350,000 litres of furnace oil, was in collision with a cargo vessel and sank in the river. By 17 December, the oil had spread over a 350 km2 (140 sq mi) area. The oil spread to a second river and a network of canals in Sundarbans, which blackened the shoreline. The spill threatened trees, plankton, and vast populations of small fish and dolphins. The spill occurred at a protected mangrove area, home to rare Irrawaddy and Ganges river dolphins. By 12 January 2015, 70,000 litres of oil had been cleaned up by local residents, the Bangladesh Navy, and the government of Bangladesh.
Environmental impact of development in the Sundarbans, is the study of environmental impact on Sundarban, the largest single tract mangrove forest. It consist of a geographical area of 9,629 square kilometres (3,718 sq mi), including 4,185 square kilometres (1,616 sq mi) of reserve forest land, and is a natural region located partly in southern Bangladesh and partly in the Indian state of West Bengal. It is ecologically a southern part of the Gangetic delta between the Hooghly river in India on the west and the Meghna river in Bangladesh on the east and is bounded by the Ganga-Padma, the Padma-Meghna on the north and by the Bay of Bengal on the south. The area that is not reserve forest land is inhabited by human settlements with a total population around 4 million (2003).
The Sundarbans settlements refer to the areas of the Sundarbans that were cleared of forests for human habitation in the present North 24 Paganas and the South 24 Parganas districts in the Indian state of West Bengal.
Nijhum Dweep National Park is a major national park and nature reserve in Bangladesh. The park is located at Hatiya Upazila, Noakhali District in the Southern region of the country. It is located on the banks of the river Meghana. It is also a part of Sunderbans Delta.
The Sundarbans Biosphere Reserve is a biosphere reserve in the Indian state of West Bengal, based on the UNESCO Man and the Biosphere (MAB) Programme list. It is one of the 18 biosphere reserves in India and the third largest in terms of area. The Biosphere Reserve is constituted of the Sundarbans area spread across South 24 Parganas and North 24 Parganas district districts of West Bengal. The Indian Sundarbans as a Biosphere Reserve is bounded by the Muri Ganga River in the west and the Hariabhanga and Raimangal rivers in the east. Sundarbans has a very rich diversity of aquatic and terrestrial flora and fauna. In fact, the highly productive ecosystems of the Sundarbans act as natural fish nurseries. It provides habitat for the Royal Bengal Tiger.
