Red River Freshwater Swamp Forests
The Red River freshwater swamp forests ecoregion (WWF ID:IM0147) covers the freshwater portion of the Hong River ("Red River") delta in northern Vietnam. The ecoregion is separated from the sea by a thin coastal strip of the saltwater mangroves of the Indochina mangroves ecoregion. Very little of the little ecosystem remains; most of the delta has been converted to urbanization, industry, or agriculture. Less than 1% of the ecoregion is protected in significantly sized tracts. Location and description The ecoregion is relatively small, just under 11,000 km2, limited to the flat river delta of the Hong River, centered on the cities of Hanoi in the center and Haiphong at the river mouth. The ecoregion is separated from the actual sea coast by a thin strip of the Indochina mangroves ecoregion in the saltwater-affected zone. To the north is the South China-Vietnam subtropical evergreen forests ecoregion, and to the west are the Northern Indochina subtropical forests and Northern ...

Vietnam
Vietnam or Viet Nam ( vi, Việt Nam, ), officially the Socialist Republic of Vietnam,., group="n" is a country in Southeast Asia, at the eastern edge of mainland Southeast Asia, with an area of and population of 96 million, making it the world's sixteenth-most populous country. Vietnam borders China to the north, and Laos and Cambodia to the west. It shares maritime borders with Thailand through the Gulf of Thailand, and the Philippines, Indonesia, and Malaysia through the South China Sea. Its capital is Hanoi and its largest city is Ho Chi Minh City (commonly known as Saigon). Vietnam was inhabited by the Paleolithic age, with states established in the first millennium BC on the Red River Delta in modern-day northern Vietnam. The Han dynasty annexed Northern and Central Vietnam under Chinese rule from 111 BC, until the first dynasty emerged in 939. Successive monarchical dynasties absorbed Chinese influences through Confucianism and Buddhism, and expanded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hanoi
Hanoi or Ha Noi ( or ; vi, Hà Nội ) is the capital and second-largest city of Vietnam. It covers an area of . It consists of 12 urban districts, one district-leveled town and 17 rural districts. Located within the Red River Delta, Hanoi is the cultural and political centre of Vietnam. Hanoi can trace its history back to the third century BCE, when a portion of the modern-day city served as the capital of the historic Vietnamese nation of Âu Lạc. Following the collapse of Âu Lạc, the city was part of Han China. In 1010, Vietnamese emperor Lý Thái Tổ established the capital of the imperial Vietnamese nation Đại Việt in modern-day central Hanoi, naming the city Thăng Long (literally 'Ascending Dragon'). Thăng Long remained Đại Việt's political centre until 1802, when the Nguyễn dynasty, the last imperial Vietnamese dynasty, moved the capital to Huế. The city was renamed Hanoi in 1831, and served as the capital of French Indochina from 1902 to 1945. O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indomalayan
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 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 Fabaceae. Major ecolog ...

Tropical And Subtropical Moist Broadleaf Forests
Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forest, is a subtropical and tropical forest habitat type defined by the World Wide Fund for Nature. Description TSMF is generally found in large, discontinuous patches centered on the equatorial belt and between the Tropic of Cancer and Tropic of Capricorn, TSMF are characterized by low variability in annual temperature and high levels of rainfall of more than annually. Forest composition is dominated by evergreen and semi-deciduous tree species. These trees number in the thousands and contribute to the highest levels of species diversity in any terrestrial major habitat type. In general, biodiversity is highest in the forest canopy. The canopy can be divided into five layers: overstory canopy with emergent crowns, a medium layer of canopy, lower canopy, shrub level, and finally understory. These forests are home to more species than any other terrestrial ecosystem: Half of the world's sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hong River
The Red River, also known as the Hong River (; vi, Sông Hồng; Chữ Nôm: 瀧紅; Chữ Hán: 紅河), the ' and ' (lit. "Mother River") in Vietnamese, and the (, ' Nguyên Giang) in Chinese, is a -long river that flows from Yunnan in Southwest China through northern Vietnam to the Gulf of Tonkin. According to C. Michael Hogan, the associated Red River Fault was instrumental in forming the entire South China Sea at least as early as 37 million years before present. The name red and southern position in China are associated in traditional cardinal directions. Geography The Red River begins in China's Yunnan province in the mountains south of Dali. Main headstreams Leqiu River, Xi River and Juli River confluence at Nanjian where they form the Lishe River. The Lishe River meets with another headstream, the Yijie River at Hongtupo, Chuxiong Prefecture. It flows generally southeastward, passing through Yi and Dai ethnic minority areas before leaving ...

Indochina Mangroves
The Indochina mangroves are a large mangrove ecoregion on the coasts of Thailand, Cambodia, Vietnam and Malaysia in Southeast Asia. Location and description Mangrove forests occur on coasts that are regularly washed with saltwater by tidal movements. There are patches of mangrove throughout the region and there were once much more. Today the largest areas remain in the Mekong delta in U Minh District and other parts of Cà Mau Province at the southern tip of Vietnam. There are smaller patches in Vietnam in Cam Ranh Bay in the south and in the Red River delta in the north. Much larger areas of mangrove habitat on the coasts of southern Vietnam including the Mekong and Red River deltas were affected by the Vietnam War when areas of mangrove were cleared or destroyed by bombing and the defoliant Agent Orange, while mangroves around Pattaya and in the Chao Phraya delta in Thailand and the Bay of Kompong Som in Cambodia have been cleared for agricultural and coastal development.

Haiphong
Haiphong ( vi, Hải Phòng, ), or Hải Phòng, is a major industrial city and the third-largest in Vietnam. Hai Phong is also the center of technology, economy, culture, medicine, education, science and trade in the Red River delta. Haiphong was founded in 1887 as a major seaport city of Vietnam. In 1888, the president of the French Third Republic, Sadi Carnot, promulgated a decree to establish Haiphong. From 1954 to 1975, Haiphong served as the most important maritime city of North Vietnam, and it became one of direct-controlled municipalities of a reunified Vietnam with Hanoi and Ho Chi Minh City in 1976. In the 21st century, Haiphong has emerged as a trading gateway, modern, green industrial city of Vietnam, oriented to become the third special-class city of Vietnam by 2030 to 2050 at the latest. Haiphong has a Human Development Index of 0.782 (high), ranking fourth among all municipalities and provinces of Vietnam. History Dynastic Vietnam Haiphong was the home of Lê C ...

South China-Vietnam Subtropical Evergreen Forests
South is one of the cardinal directions or Points of the compass, compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic language, Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European language, Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', cf English meridional), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the ...

Northern Indochina Subtropical Forests
The Northern Indochina subtropical moist forests are a subtropical moist broadleaf forest ecoregion of northern Indochina, covering portions of Vietnam, Laos, Thailand, Myanmar, and China's Yunnan Province. Setting The Northern Indochina subtropical forests occupy the highlands of northern Indochina, extending from northeastern Vietnam, where they cover the upper portion of the Red River watershed and the northern Annamite Range, across northern Laos, northernmost Thailand, and southeastern Yunnan to Shan State in eastern Myanmar. The ecoregion includes Fan Si Pan (), Vietnam's highest mountain. The Northern Indochina subtropical forests are a transition between the tropical forests of Indochina and the subtropical and temperate forests of China and the Tibetan Plateau.Wikramanayake, Eric; Eric Dinerstein; Colby J.

Northern Vietnam Lowland Rain Forests
The Northern Vietnam lowland rain forests ecoregion (WWF ID: IM0141) covers the central-eastern coast of Vietnam from the Red River delta in the north to Tam Kỳ in the center of the country and neighboring adjacent parts of Laos. The region is one of the wet evergreen forests, with rain over 50 mm in every month. The forests have been highly degraded by human use, and the high levels of biodiversity have been pushed back into relatively small protected areas like Pu Mat National Park. Location and description The region is about 380 km from north to south, and about 50 km wide on average. It is bounded by the coast on the east, and the Northern Annamites rain forests to the west. The geological base features extensive limestone ('karst') mountains and valleys. Elevations range from sea level to 1,000 meters, with an average of 88 meters. The primary wet evergreen forest has mostly been cleared in the past by humans; by one estimate only 10% of the original remains. ...
