North Sentinel Island
North Sentinel Island is one of the Andaman Islands, an Indian archipelago in the Bay of Bengal which also includes South Sentinel Island. It is home to the Sentinelese, an indigenous people in voluntary isolation who have defended, often by force, their protected isolation from the outside world. The Andaman and Nicobar Islands Protection of Aboriginal Tribes Act of 1956 prohibits travel to the island, and any approach closer than , in order to protect the remaining tribal community from "mainland" infectious diseases which they (likely) have no acquired immunity against. The area is patrolled by the Indian Navy. Nominally, the island belongs to the South Andaman administrative district, part of the Indian union territory of Andaman and Nicobar Islands. In practice, Indian authorities recognise the islanders' desire to be left alone, restricting outsiders to remote monitoring (by boat and sometimes air) from a reasonably safe distance; the Indian government will not prosecu ...

Bay Of Bengal
The Bay of Bengal is the northeastern part of the Indian Ocean, bounded on the west and northwest by India, on the north by Bangladesh, and on the east by Myanmar and the Andaman and Nicobar Islands of India. Its southern limit is a line between Sangaman Kanda, Sri Lanka, and the north westernmost point of Sumatra, Indonesia. It is the largest water region called a bay in the world. There are countries dependent on the Bay of Bengal in South Asia and Southeast Asia. During the existence of British India, it was named as the Bay of Bengal after the historic Bengal region. At the time, the Port of Kolkata served as the gateway to the Crown rule in India. Cox's Bazar, the longest sea beach in the world and Sundarbans, the largest mangrove forest and the natural habitat of the Bengal tiger, are located along the bay. The Bay of Bengal occupies an area of . A number of large rivers flow into the Bay of Bengal: the Ganges– Hooghly, the Padma, the Brahmaputra–Yamuna, the Barak†...

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the Program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking. History In 1985, following a specific request from the European Economic Community, Birdlife International ...

Coconut Crab
The coconut crab (''Birgus latro'') is a species of terrestrial hermit crab, also known as the robber crab or palm thief. It is the largest terrestrial arthropod in the world, with a weight of up to . It can grow to up to in width from the tip of one leg to the tip of another. It is found on islands across the Indian Ocean, and parts of the Pacific Ocean as far east as the Gambier Islands, Pitcairn Islands and Caroline Island, similar to the distribution of the coconut palm; it has been extirpated from most areas with a significant human population, including mainland Australia and Madagascar. Coconut crabs also live off the coast of Africa near Zanzibar. The coconut crab is the only species of the genus ''Birgus'', and is related to the other terrestrial hermit crabs of the genus ''Coenobita''. It shows a number of adaptations to life on land. Juvenile coconut crabs use empty gastropod shells for protection like other hermit crabs, but the adults develop a tough exoskeleton on ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ...

Bombax Ceiba
''Bombax ceiba'', like other trees of the genus ''Bombax'', is commonly known as cotton tree. More specifically, it is sometimes known as Malabar silk-cotton tree; red silk-cotton; red cotton tree; or ambiguously as silk-cotton or kapok, both of which may also refer to ''Ceiba pentandra''. This Asian tropical tree has a straight tall trunk and its leaves are deciduous in winter. Red flowers with 5 petals appear in the spring before the new foliage. It produces a capsule which, when ripe, contains white fibres like cotton. Its trunk bears spikes to deter attacks by animals. Although its stout trunk suggests that it is useful for timber, its wood is too soft to be very useful. Description ''Bombax ceiba'' grows to an average of 20 meters, with old trees up to 60 meters in wet tropical regions. The trunk and limb bear numerous conical spines particularly when young, but get eroded when older. The leaves are palmate with about 6 leaflets radiating from a central point (tip of pe ...

Buttress Root
Buttress roots also known as plank roots are large, wide roots on all sides of a shallowly rooted tree. Typically, they are found in nutrient-poor tropical forest soils that may not be very deep. They prevent the tree from falling over (hence the name buttress) while also gathering more nutrients. Buttresses are tension elements, being larger on the side away from the stress of asymmetrical canopies. The roots may intertwine with buttress roots from other trees and create an intricate mesh, which may help support trees surrounding it. They can grow up to tall and spread for 30 metres above the soil then for another 30 metres below. When the roots spread horizontally, they are able to cover a wider area for collecting nutrients. They stay near the upper soil layer because all the main nutrients are found there. Buttress roots vary greatly in size from barely discernable to many square yards (square meters) of surface. The largest for which there is photographic evidence is a More ...

Manilkara
''Manilkara'' is a genus of trees in the family Sapotaceae. They are widespread in tropical and semitropical locations, in Africa, Madagascar, Asia, Australia, and Latin America, as well as various islands in the Pacific and in the Caribbean. A close relative is the genus ''Pouteria''. Trees of this genus yield edible fruit, useful wood, and latex. The best-known species are '' M. bidentata'' (''balatá''), '' M. chicle'' (chicle) and '' M. zapota'' (sapodilla). ''M. hexandra'' is the floral emblem of Prachuap Khiri Khan Province in Thailand, where it is known as ''rayan''. ''M. obovata'' shares the vernacular name of African pear with another completely different species, '' Dacryodes edulis'', and neither should be confused with '' Baillonella toxisperma'', known by the very similar name, African pearwood. The generic name, ''Manilkara'', is derived from ''manil-kara'', a vernacular name for '' M. kauki'' in Malayalam. ''Manilkara'' trees are often significant, or even do ...

Maurice Vidal Portman
Maurice Vidal Portman (21 March 1860 – 14 February 1935) was a British naval officer, who is best known for documenting several Andamanese tribes between 1879 and 1901 when he was posted as a superintendent of the Andaman Island Penal Colony. Life and career Portman was born in Canada, the third son of Maurice Berkeley Portman and Helen Vidal Harris. His father was in turn the third son of Edward Portman, 1st Viscount Portman, and Emma Portman, Baroness Portman. He joined the Royal Indian Marine at the age of 16 and was some time in charge of the Viceroy's yacht. In July 1879 he was stationed at Port Blair in the Andaman Islands and made Officer in Charge of the Andamanese, a post which he held for more than 20 years with few interruptions (including December 1880 to December 1883 on sick leave, March 1887 to March 1888 on furlough).
