Himalayan Subtropical Broadleaf Forests
The Himalayan subtropical broadleaf forests is an ecoregion that extends from the middle hills of central Nepal through Darjeeling into Bhutan and also into the Indian States of Uttar Pradesh and Bihar. It represents the east-west-directed band of subtropical broadleaf forest at an altitude of between along the Outer Himalayan Range, and includes several forest types traversing an east to west moisture gradient.Rawat, G. S., Wikramanayake, E. D. (2002''Himalayan subtropical broadleaf forests'' In: Wikramanayake, E. D. (ed.) ''Terrestrial ecoregions of the Indo-Pacific: a conservation assessment''. Island Press Geography The ecoregion covers an area of and is bisected by the Kali Gandaki River, which has gouged the world's deepest river valley through the Himalayan Range. It forms a critical link in the chain of interconnected Himalayan ecosystems, where altitudinal connectivity between the habitat types is important for ecosystem function.

Kali Gandaki River
The Gandaki River, also known as the Narayani and the Gandak, is one of the major rivers in Nepal and a left bank tributary of the Ganges in India. Its total catchment area amounts to , most of it in Nepal. In the Nepal Himalayas, it is notable for its deep canyon. The basin also contains three mountains over , namely Dhaulagiri, Manaslu and Annapurna I. Dhaulagiri is the highest point of the Gandaki basin. River course Nepal The Kali Gandaki river source is at the border with Tibet at an elevation of at the Nhubine Himal Glacier in the Mustang region of Nepal. The headwaters stream on some maps is named the Chhuama Khola and then, nearing Lo Manthang, the Nhichung Khola or Choro Khola. The Kali Gandaki then flows southwest (with the name of Mustang Khola on old, outdated maps) through a sheer-sided, deep canyon before widening at the steel footbridge at Chele, where part of its flow funnels through a rock tunnel, and from this point the now wide river is called the Kali ...

Threatened Species
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species *Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data ( data deficient) also are not considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sal Tree
''Shorea robusta'', the sal tree, sāla, shala, sakhua, or sarai, is a species of tree in the family Dipterocarpaceae. The tree is native to India, Bangladesh, Nepal, Tibet and across the Himalayan regions . Evolution Fossil evidence from lignite mines in the Indian states of Rajasthan and Gujarat indicate that sal trees (or at least a closely related ''Shorea'' species) have been a dominant tree species of forests of the Indian subcontinent since at least the early Eocene (roughly 49 million years ago), at a time when the region otherwise supported a very different biota from the modern day. Evidence comes from the numerous amber nodules in these rocks, which originate from the dammar resin produced by the sal trees. Description ''Shorea robusta'' can grow up to tall with a trunk diameter of . The leaves are 10–25 cm long and 5–15 cm broad. In wetter areas, sal is evergreen; in drier areas, it is dry-season deciduous, shedding most of the leaves from February t ...

Siwalik
The Sivalik Hills, also known as the Shivalik Hills and Churia Hills, are a mountain range of the outer Himalayas that stretches over about from the Indus River eastwards close to the Brahmaputra River, spanning the northern parts of the Indian subcontinent. It is wide with an average elevation of . Between the Teesta and Raidāk Rivers in Assam is a gap of about . "Sivalik" literally means 'tresses of Shiva'. Sivalik region is home to the Soanian archaeological culture. Geology Geologically, the Sivalik Hills belong to the Tertiary deposits of the outer Himalayas. They are chiefly composed of sandstone and conglomerate rock formations, which are the solidified detritus of the Himalayas to their north; they are poorly consolidated. The remnant magnetisation of siltstones and sandstones indicates that they were deposited 16–5.2 million years ago. In Nepal, the Karnali River exposes the oldest part of the Shivalik Hills. They are bounded on the south by a fault system ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olea Cuspidata
''Olea europaea'' subsp. ''cuspidata'' is a subspecies of the well-known olive tree (''Olea europaea''), which until recently was considered a separate species (''Olea africana'') and is still mentioned as such in many sources. Native to northeast of Africa and the drier parts of subtropical Asia, it has various common names, including wild olive, African olive, brown olive and Indian olive. It is the ancestor of the cultivated olive and it has been introduced to Australia, New Zealand and the US. It is an aggressive invasive species that can infest dry woodland areas, riparian zones, headlands and dune systems.Olea europaea subsp. cuspidata (wild olive) CAB International.

Dodonaea
''Dodonaea'' is a genus of about 70 species of flowering plants, often known as hop-bushes, in the soapberry family, Sapindaceae. It has a cosmopolitan distribution in tropical, subtropical and warm temperate regions of Africa, the Americas, southern Asia and Australasia. By far the highest species diversity is in Australia. The genus is named after Rembert Dodoens, traditionally known as 'Dodonaeus'. They are shrubs and small trees growing to tall. The leaves are alternate, simple or pinnate. The flowers are produced in short racemes. The fruit is a capsule, often with two or three wings. ''Dodonaea'' species are used as food plants by the larvae of some Lepidoptera species including '' Aenetus eximia'' and '' Aenetus ligniveren''. Systematics ''Dodonaea'' is one of the largest genera in the Sapindaceae, and includes 70 species widely distributed in continental Australia. The only other species of the ''Dodonaea'' widely spread beyond mainland Australia, ''Dodonaea vis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biogeographic Realm
A biogeographic realm or ecozone is the broadest biogeographic division of Earth's land surface, based on distributional patterns of terrestrial organisms. They are subdivided into bioregions, which are further subdivided into ecoregions. Description The realms delineate large areas of Earth's surface within which organisms have evolved in relative isolation over long periods of time, separated geographic features, such as oceans, broad deserts, or high mountain ranges, that constitute natural barriers to migration. As such, biogeographic realm designations are used to indicate general groupings of organisms based on their shared biogeography. Biogeographic realms correspond to the floristic kingdoms of botany or zoogeographic regions of zoology. From 1872, Alfred Russel Wallace developed a system of zoogeographic regions, extending the ornithologist Philip Sclater's system of six regions. Biogeographic realms are characterized by the evolutionary history of the orga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palearctic
The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Siberian region; the Mediterranean Basin; the Sahara and Arabian Deserts; and Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. The term 'Palearctic' was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/Afrotropic, Indian/Indomalayan, Australasian, Nearctic, and Neotropical. The six indicated general groupings of fauna, based on shared biogeography and large-scale geographic barriers to migration. Alfred Wallace a ...

Indomalaya
The Indomalayan realm is one of the eight biogeographic realms. It extends across most of South and Southeast Asia and into the southern parts of East Asia. Also called the Oriental realm by biogeographers, Indomalaya spreads all over the Indian subcontinent and Southeast Asia to lowland southern China, and through Indonesia as far as Sumatra, Java, Bali, and Borneo, east of which lies the Wallace line, the realm boundary named after Alfred Russel Wallace which separates Indomalaya from Australasian realm, Australasia. Indomalaya also includes the Philippines, lowland Taiwan, and Japan's Ryukyu Islands. Most of Indomalaya was originally covered by forest, and includes tropical and subtropical moist broadleaf forests, with tropical and subtropical dry broadleaf forests predominant in much of India and parts of Southeast Asia. The tropical forests of Indomalaya are highly variable and diverse, with economically important trees, especially in the families Dipterocarpaceae and Faba ...

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 ...

Monsoon
A monsoon () is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator. Usually, the term monsoon is used to refer to the rainy phase of a seasonally changing pattern, although technically there is also a dry phase. The term is also sometimes used to describe locally heavy but short-term rains. The major monsoon systems of the world consist of the West African, Asia–Australian, the North American, and South American monsoons. The term was first used in English in British India and neighboring countries to refer to the big seasonal winds blowing from the Bay of Bengal and Arabian Sea in the southwest bringing heavy rainfall to the area.
