Eastern Himalayan Broadleaf Forests
The Eastern Himalayan broadleaf forests is a temperate broadleaf forest ecoregion found in the middle elevations of the eastern Himalayas, including parts of Nepal, India, and Bhutan. These forests have an outstanding richness of wildlife. Setting This ecoregion covers an area of and constitutes a band of temperate broadleaf forests lying on steep mountain slopes of the Himalayas between approximately . It extends from the Kali Gandaki River in Nepal across Sikkim and West Bengal in India, Bhutan, and the Indian state of Arunachal Pradesh. The temperate broadleaf forests transition into the Himalayan subtropical pine forests and the Himalayan subtropical broadleaf forests at lower elevations, and into the Eastern Himalayan subalpine conifer forests at higher elevations. This area receives over 2000 mm of rainfall per year, mostly falling from May to September during the monsoon. Flora The Eastern Himalayan broadleaf forests are diverse and species-rich, with a great diversity (o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jigme Dorji National Park
The Jigme Dorji National Park (JDNP), named after the late Jigme Dorji Wangchuck, is the second-largest National Park of Bhutan. It occupies almost the entire Gasa District, as well as the northern areas of Thimphu District, Paro District, Punakha, and Wangdue Phodrang Districts. It was established in 1974 and stretches over an area of 4316 km², thereby spanning all three climate zones of Bhutan, ranging in elevation from 1400 to over 7000 meters.

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 The Kali Gandaki then flows southwest (with the name of Mustang Khola on old, outdated maps) through a sheer-sided, deep canyon before widening at the steel footbridge at Chele, where part of its flow funnels through a rock tunnel, and from this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 ...

Lithocarpus Pachyphylla
''Lithocarpus'' is a genus in the beech family, Fagaceae. Trees in this genus are commonly known as the stone oaks and differ from ''Quercus'' primarily because they produce insect-pollinated flowers on erect spikes and the female flowers have short styles with punctate stigmas. At current, around 340 species have been described, mostly restricted to Southeast Asia. Fossils show that ''Lithocarpus'' formerly had a wider distribution, being found in North America and Europe during the Eocene to Miocene epochs. The species extend from the foothills of the Hengduan Mountains, where they form dominant stands of trees, through Indochina and the Malayan Archipelago, crossing Wallace's Line and reaching Papua. In general, these trees are most dominant in the uplands (more than above sea level) and have many ecological similarities to the Dipterocarpaceae, the dominant lowland tree group. These trees are intolerant of seasonal droughts, not being found on the Lesser Sunda Islands, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Lamellosa
''Quercus lamellosa'' (syn. ''Cyclobalanopsis lamellosa'') is a species of oak native to the Himalaya and adjoining mountains from Tibet and Nepal east as far as Guangxi and northern Thailand, growing at altitudes of 1300–2500 m. The Lepcha of Sikkim call it . ''Quercus lamellosa'' is a medium-sized to large evergreen tree growing to 40 m tall with a trunk up to 1.5 m diameter.

The flowers are catkins, the female flowers maturing into broad acorns 2–3 cm long and 3–4 cm broad, set in a deep cupule with concentric rings of woody scales. Joseph Dalton Hooker commented, :"The present is one of the commonest trees about Dorjiling, and is certainly by far the noblest species of Oak known, whether from the size of the foliage or acorns, the texture and colour, or the imposing appearance of the tree." ''Quercus lamellosa'' is occasionally c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gondwana
Gondwana () was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic period (about 180 million years ago). The final stages of break-up, involving the separation of Antarctica from South America (forming the Drake Passage) and Australia, occurred during the Paleogene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it. To differentiate it from the Indian region of the same name (see ), it is also commonly called Gondwanaland. Gondwana was formed by the accretion of several cratons. Eventually, Gondwana became the largest piece of continental crust of the Palaeozoic Era, covering an area of about , about one-fifth of the Earth's surface. During the Carboniferous Period, it merged with Laurasia to form a larger supercontinent called Pangaea. Gondwana (and Pan ...

Eastern Asiatic Region
The Eastern Asiatic Region (also known as Oriasiaticum, Sino-Japanese Region, East Asian Region, Temperate Eastern Region) is the richest floristic region within the Holarctic Kingdom and situated in temperate East Asia. It has been recognized as a natural floristic area since 1872 August Grisebach's volume ''Die Vegetation der Erde'' and later delineated by such geobotanists as Ludwig Diels, Adolf Engler (as Temperate Eastern region), Ronald Good (as Sino-Japanese Region) and Armen Takhtajan. The Eastern Asiatic Region is dominated by very old lineages of gymnosperms and woody plant families and is thought to be the cradle of the Holarctic flora. Moreover, this floristic region wasn't significantly glaciated in the Pleistocene, and many relict Tertiary genera (such as ''Metasequoia glyptostroboides'', ancestors of which were once common throughout the Northern Hemisphere up to subpolar latitudes) found refuge here. Endemic flora The Eastern Asiatic Region endemic flora is chara ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indochina
Mainland Southeast Asia, also known as the Indochinese Peninsula or Indochina, is the continental portion of Southeast Asia. It lies east of the Indian subcontinent and south of Mainland China and is bordered by the Indian Ocean to the west and the Pacific Ocean to the east. It includes the countries of Cambodia, Laos, Myanmar, Thailand and Vietnam, with peninsular Malaysia sometimes also being included. The term Indochina (originally Indo-China) was coined in the early nineteenth century, emphasizing the historical cultural influence of Indian and Chinese civilizations on the area. The term was later adopted as the name of the colony of French Indochina (today's Cambodia, Laos, and Vietnam). Today, the term, Mainland Southeast Asia, in contrast to Maritime Southeast Asia, is more commonly referenced. Terminology The origins of the name Indo-China are usually attributed jointly to the Danish-French geographer Conrad Malte-Brun, who referred to the area as in 1804, and the ...

Rhododendron
''Rhododendron'' (; from Ancient Greek ''rhódon'' "rose" and ''déndron'' "tree") is a very large genus of about 1,024 species of woody plants in the heath family (Ericaceae). They can be either evergreen or deciduous. Most species are native to eastern Asia and the Himalayan region, but smaller numbers occur elsewhere in Asia, and in North America, Europe and Australia. It is the national flower of Nepal, the state flower of Washington and West Virginia in the United States, the state flower of Nagaland in India, the provincial flower of Jiangxi in China and the state tree of Sikkim and Uttarakhand in India. Most species have brightly colored flowers which bloom from late winter through to early summer. Azaleas make up two subgenera of ''Rhododendron''. They are distinguished from "true" rhododendrons by having only five anthers per flower. Species Description ''Rhododendron'' is a genus of shrubs and small to (rarely) large trees, the smallest species growing to t ...

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.
