mekong river species

For decades, Cambodia’s Mekong River population of Irawaddy dolphins has verged on extinction. The goal of the Mekong Conservation Heroes program is to shine a spotlight on inspiring individuals in the Lower Mekong Basin working to study, protect, or raise awareness about the Mekong River’s unique ecosystem, biodiversity, habitats, and cultural heritage. [43][44][48] They provide a principal form of income for numerous people and act as a safety net and coping strategy in times of poor agricultural harvests or other difficulties. Economy. The mountainous landscape means that only 16% of the country is farmed under lowland terrace or upland shifting cultivation. One campaign in particular that he takes special pride in involved the efforts to protect Cantor’s Giant Softshell Turtle, an endangered species inhabiting the Mekong River and the largest freshwater turtle in the world. Then the Mekong shortly afterwards splits up again into two big arms; one of them is called the Bassac River, the other one is still called the Mekong, although both are Mekong streams. National Geographic term it as the “world’s most productive river” due to its plethora of fish and its tendency to product array of “mega-fish” such as the giant catfish. Migration status is known for only 24% of those species, and of those, 87% are migratory . This reach is almost entirely mountainous and covered with natural forest although there has been widespread slash and burn agriculture. Kuenzer, C., I. Campbell, M. Roch, P. Leinenkugel, V. Q. Tuan and S. Dech (2012): Understanding the impact of hydropower developments in the context of upstream–downstream relations in the Mekong river basin. Sun bear The Mekong Basin houses over 850 species of fish, making it second only to the Amazon. The species is considered virtually extinct in the wild with numbers estimated between 50 and 4,000 in Thailand due to habitat destruction and hunting for skins. [12], The internal drainage patterns of the Mekong are unusual when compared to those of other large rivers. 15°6′19.95″N 105°48′49.51″E / 15.1055417°N 105.8137528°E / 15.1055417; 105.8137528 (Pakxe)). The very flat Mekong delta area in Vietnam is thus prone to flooding, especially in the provinces of An Giang and Dong Thap (Đồng Tháp), near the Cambodian border. This makes the Mekong second to only the Amazon for the variety of fish species present. Runoff in the mainstream increases again with the entry from the left bank of the Se Kong from southern Laos and Se San and Sre Pok from Vietnam and Cambodia. Some of the highlights of the city are its Tropical Plant Institute, which boasts 13,000 species on site, and Manting Park, which has over 1,300 years of history behind it. The Mekong River is a globally important river system, known for its unique flood pulse hydrology, ecological productivity, and biodiversity. The Mekong is also home to some of the world’s largest freshwater animal species. The focus turns from hydrology and water discharge to the assessment of water level, over- bank storage and flooding and the hydrodynamics that determine the timing, duration and volume of the seasonal flow reversal into and out of the Great Lake. [25] At this time the delta was advancing at a rate of 17–18 m per year. Little is known about these magnificent species of the Greater Mekong region, some attaining five metres in length and over half a ton in weight. The Mekong River is the world’s second-most biodiverse river, after the Amazon River, with the largest freshwater fishery [3]. Only the Amazon boasts a higher level of bio-diversity. It swells over four times its smallest size to 14,500 square kilometres at the height of the floods, according to the Mekong River Commission (MRC) - an area bigger than Lebanon.

The Mekong River is the second most biodiverse river in the world (after the Amazon River). The most important and abundant resource of the Mekong River is water and biodiversity. [12], Reach 4: Pakse to Kratie. The declines of the Murray cod of the Murray-Darling river system in Australia, some sturgeon stocks of Eurasia, the tilapiine species Oreochromis esculentus and Oreochromis variabilisof Lake Victoria, and perhaps the Pacific salmon of the Columbia River are examples of the historical influence of overharvest. Excavations at Oc Eo, near modern An Giang, have found coins from as far away as the Roman Empire. Just after the Amazon River Basin, the Mekong River is often considered to be the second most diverse area on Earth. Background: The Lower Mekong river basin supports a high diversity of aquatic species. Officials are particularly concerned as July is in the wet season, when mainstream flows are abundant historically. Freshwater ecosystems are however undervalued and receive insufficient funding, political attention and protection. The main hydrological contributions to the mainstream in this reach come from the Se Kong, Se San, and Sre Pok catchments. The Mekong giant catfish and the Nile perch of Lake Victoria provide contemporary cases. In Yunnan Province in China, the river and its tributaries are confined by narrow, deep gorges. There are approximately 20,000 plant species, 850 fish species, 430 mammals, 800 reptiles and 1,200 species of bird. Kuenzer, C., P. Leinenkugel, M. Vollmuth and S. Dech (2014): Comparing global land-cover products – implications for geoscience applications: an investigation for the trans-boundary Mekong Basin. ► Find out more about these species. Working to sustain the natural world for the benefit of people and nature. They urge an immediate moratorium on new construction and a shift to solar and other forms of renewable energy, already highly competitive and faster to install.[69]. Only the Amazon boasts a higher level of bio-diversity. Flussname. But really peculiar is here that the Tonle Sap , who is over months in the dry season feeding the Mekong, in monsoon turns into a sidearm of the Mekong, receiving water from the main stream. It is 1,380 meters (4,528 ft) long, and was completed in 2000. Kuenzer, C., H. Guo, J. Huth, P. Leinenkugel, X. Li and S. Dech (2013): Flood Mapping and Flood Dynamics of the Mekong Delta. 2747–2751. From the Tibetan Plateau the river runs through China, Myanmar, Laos, Thailand, Cambodia, and Vietnam. Cargos carried are timber, agricultural products, and construction materials. Khon Pi Long is a series of rapids along a 1.6-kilometre section of the Mekong River dividing Chiang Rai and Bokeo Province in Laos. Many people choose to explore this part of South East Asia through a cruise or boat journey down a section of the Mekong River. Consequently, although the Mun and Chi basins drain 15% of the entire Mekong basin, they only contribute 6% of the average annual flow. The Mekong rises as the Za Qu (Tibetan: .mw-parser-output .uchen{font-family:"BabelStone Tibetan Slim",Jomolhari,"Noto Sans Tibetan","Microsoft Himalaya",Kailash,"DDC Uchen","TCRC Youtso Unicode","Tibetan Machine Uni","Qomolangma-Uchen Sarchen","Qomolangma-Uchen Sarchung","Qomolangma-Uchen Suring","Qomolangma-Uchen Sutung","Qomolangma-Title","Qomolangma-Subtitle","DDC Rinzin","Qomolangma-Woodblock","Qomolangma-Dunhuang"}.mw-parser-output .ume{font-family:"Qomolangma-Betsu","Qomolangma-Chuyig","Qomolangma-Drutsa","Qomolangma-Edict","Qomolangma-Tsumachu","Qomolangma-Tsuring","Qomolangma-Tsutong","TibetanSambhotaYigchung","TibetanTsugRing","TibetanYigchung"}རྫ་ཆུ་, Wylie: rDza chu, ZYPY: Za qu; Chinese: 扎曲; pinyin: Zā Qū) and soon becomes known as the Lancang (simplified Chinese: 澜沧江; traditional Chinese: 瀾滄江; pinyin: Láncāng Jiāng, from the old name of Lao kingdom Lan Xang; the characters may also be literally understood as "turbulent green river").
