Brahmaputra Valley Semi-evergreen Forests
The Brahmaputra Valley semi-evergreen forests is a tropical moist broadleaf forest ecoregion of Northeastern India, southern Bhutan and adjacent Bangladesh. Location and description The ecoregion covers and encompasses the alluvial plain of the upper Brahmaputra River as it moves westward through India's Assam state (with small parts of the ecoregion in the states of Arunachal Pradesh and Nagaland and also south Bhutan and northern Bangladesh). The valley lies between the Himalayas to the north and the Lushai hills to the south and when the river floods during the June to September monsoon it brings up to 300 cm of water onto the plain carrying rich soils to create a fertile environment which has been extensively farmed for thousands of years. Other rivers that water the plains as well as the Brahmaputra include the Manas River, Manas and the Subansiri River, Subansiri. Flora The extensive farming has meant that the original semi-evergreen forest now exists only in patches. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manas National Park
Manas National Park is a national park, Project Tiger reserve, and an elephant reserve in Assam, India. Located in the Himalayan foothills, it borders the Royal Manas National Park in Bhutan. The park is known for its rare and endangered endemic wildlife such as the Assam roofed turtle, hispid hare, golden langur and pygmy hog. It also hosts the only known population of Pygmy hog, pygmy hogs in the world. Manas is also famous for its population of the wild water buffalo. Because of its exceptional biodiversity, scenery, and variety of habitats, Manas National Park is a Biosphere Reserve, biosphere reserve and a UNESCO World Heritage Site. Origin of the name The name of the park is originated from the Manas River. The Manas river is a major tributary of Brahmaputra River, which passes through the heart of the national park. History The area today consisting of the Manas National Park was under the Kingdom of Bhutan till the Duar War of 1865 when it was ceded to British Ind ...

Alluvial Plain
An alluvial plain is a plain (an essentially flat landform) created by the deposition of sediment over a long period by one or more rivers coming from highland regions, from which alluvial soil forms. A ''floodplain'' is part of the process, being the smaller area over which the rivers flood at a particular time. In contrast, the alluvial plain is the larger area representing the region over which the floodplains have shifted over geological time. As the highlands erode due to weathering and water flow, the sediment from the hills is transported to the lower plain. Various creeks will carry the water further to a river, lake, bay, or ocean. As the sediments are deposited during flood conditions in the floodplain of a creek, the elevation of the floodplain will be raised. As this reduces the channel floodwater capacity, the creek will, over time, seek new, lower paths, forming a meander (a curved path). The leftover higher locations, typically natural levees at the margins of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lauraceae
Lauraceae, or the laurels, is a plant Family (biology), family that includes the bay laurel, true laurel and its closest relatives. This family comprises about 2850 known species in about 45 genus (biology), genera worldwide. They are dicotyledons, and occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Many are aromatic evergreen trees or shrubs, but some, such as ''Sassafras'', are deciduous, or include both deciduous and evergreen trees and shrubs, especially in tropical and temperate climates. The genus ''Cassytha'' is unique in the Lauraceae in that its members are parasite, parasitic vines. Most laurels are highly poisonous. Overview The family has a worldwide distribution in tropical and warm climates. The Lauraceae are important components of tropical forests ranging from low-lying to Montane forest, montane. In several forested regions, Lauraceae are among the top five families in terms of the number of species present. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetrameles
''Tetrameles'' is a genus of flowering plants in the family Tetramelaceae with one species, ''Tetrameles nudiflora''. It grows as a large deciduous tree and is found across southern Asia from India through southeast Asia, Malesia, and into northern Australia. The largest tree in Thailand is of this species, and was measured on February 29, 2016 by dendrologist Marc Meyer using a Nikon Forestry 500/pro laser. Its height is exactly 64.20 meters (210ft 7in) with a girth of exactly 24.20 meters ( 25ft 6in). Taxonomy Robert Brown described ''Tetrameles nudiflora'' in 1844, from material collected in Java. It is the only species in its genus ''Tetrameles'', and together with '' Octomeles sumatrana'' comprise the only two species in the family Tetramelaceae. They were previously classified in the Datiscaceae but found genetically to not form a natural clade with the other members of that family.

Magnoliaceae
The Magnoliaceae () are a flowering plant family, the magnolia family, in the order Magnoliales. It consists of two genera: '' Magnolia'' and ''Liriodendron'' (tulip trees). Unlike most angiosperms, whose flower parts are in whorls (rings), the Magnoliaceae have their stamens and pistils in spirals on a conical receptacle. This arrangement is found in some fossil plants and is believed to be a basal or early condition for angiosperms. The flowers also have parts not distinctly differentiated into sepals and petals, while angiosperms that evolved later tend to have distinctly differentiated sepals and petals. The poorly differentiated perianth parts that occupy both positions are known as tepals. The family has about 219 species and ranges across subtropical eastern North America, Mexico and Central America, the West Indies, tropical South America, southern and eastern India, Sri Lanka, Indochina, Malesia, China, Japan, and Korea.

Syzygium
''Syzygium'' () is a genus of flowering plants that belongs to the myrtle family, Myrtaceae. The genus comprises about 1200 species, and has a native range that extends from Africa and Madagascar through southern Asia east through the Pacific. Its highest levels of diversity occur from Malaysia to northeastern Australia, where many species are very poorly known and many more have not been described taxonomically. One indication of this diversity is in leaf size, ranging from as little as a half inch (one cm) to as great as 4 ft 11 inches (1.5 meters) by sixteen inches (38 centimeters) in '' Syzygium acre'' of New Caledonia. Most species are evergreen trees and shrubs. Several species are grown as ornamental plants for their attractive glossy foliage, and a few produce edible fruits called roseapples that are eaten fresh or used in jams and jellies.

Subansiri River
The Subansiri (Chayul Chu in Tibet) is a trans- Himalayan river and a tributary of the Brahmaputra River that flows through Tibet's Lhuntse County in the Shannan Prefecture in Southwestern China, and the Indian states of Arunachal Pradesh and Assam. The Subansiri is approximately long, with a drainage basin . It is the largest tributary of the Brahmaputra contributing 7.92% of the Brahmaputra's total flow. Name and etymology The name is derived from a Sanskrit word ''svarṇa'' (), meaning 'gold'. Originally the name applied to the river only after the confluence of the Chayul Chu and Tsari Chu rivers at Gelensiniak. In early maps of independent India, Tsari Chu was marked as the main Subansiri river. However, over time, the name has been transferred to Chayul Chu. Within Tibet, the rivers are named after the locations they flow from such as Loro Chu, Nye Chu, Char Chu and Chayul Chu, all of which apply to the Subansirir or its tributaries.

Manas River
The Manas River (pron: �mʌnəs, known in Bhutan as the Drangme Chhu, is a transboundary river in the Himalayan foothills between southern Bhutan, India, and China. It is the largest of Bhutan's four major river systems, with the other three being the Amo Chu or Torsa River, the Wang Chu or Raidak, and the Puna Tshang Chu or Sankosh. It is met by three other major streams before it again debouches into India in western Assam. The river flows for a total length of , including through Tibet for , Bhutan for , and Assam for before it joins the mighty Brahmaputra River at Jogighopa. A major tributary of the Manas, the Aie River, joins it in Assam at Bangpari. The Manas river valley has two major forest reserves, namely Royal Manas National Park (, established in 1966) in Bhutan and the contiguous Manas Wildlife Sanctuary (established at in 1955 and increased to in December 1985), encompassing a Project Tiger reserve, an elephant reserve and a biosphere reserve, which con ...
