Northern Annamites Rain Forests
The Northern Annamites rain forests ecoregion (WWF ID: IM0136) covers the rugged and relatively unexplored northern Annamite Mountains of central Laos and Vietnam. There are high numbers of endemic plant species, and the relative remoteness and isolation of the area supports many rare and endangered animals. Rainfall is somewhat less than the lowland rainforest of the lower elevations in Vietnam, and the temperatures slightly cooler due to the higher altitude. Location and description Most of the ecoregion is in central Laos, with a small portion on the eastern edge of the higher ridge of Annamite Range in Vietnam. The region is about 350 km long, and is at most about 150 km wide. Mean elevation is , with a highest point of . Human density is relatively low due to the steep slopes and high elevations. Climate The climate of the ecoregion is '' Dry-winter humid subtropical climate'' (Köppen climate classification (Cwa)). This climate is characterized as having no month ...

Pù Mát National Park
Pù Mát National Park (Vietnamese: ''Vườn quốc gia Pù Mát'') is a national park in Nghệ An Province, in Vietnam's North Central Coast region. It is part of the Western Nghệ An Biosphere Reserve. In the Thai language, Pù Mát means "high slope". This park was established by Decision 174/2001/QĐ-TTg, dated November 8, 2001, by the Prime Minister of Vietnam on upgrading Pù Mát Preservation Zone. This park is situated from N 18°46′to 19°12′and from E 104°24′to 104°56′. The park covers an area of 94,804 ha, spreading in three districts of Tương Dương, Con Cuông and Anh Sơn of Nghệ An Province. Of the total area, the strictly protected area comprises 89.517 ha, and the ecological recovery area comprises 1.596 ha. A buffer area covers 86.000 ha. Biodiversity values 2,461 plant species have been confirmed to occur at Pù Mát, some of which may be new to science; taxonomic work is currently underway to confirm this.

Douc Langur
The doucs or douc langurs make up the genus ''Pygathrix''. They are colobine Old World monkeys, native to Southeast Asia, which consists of these 3 species: red-shanked douc, black-shanked douc, and gray-shanked douc. Description The doucs are colobine Old World monkeys, which make up the genus ''Pygathrix''. They are native to Southeast Asia. Classification The doucs make up the genus ''Pygathrix'', which consists of these 3 species: * Red-shanked douc, ''Pygathrix nemaeus'' * Black-shanked douc, ''Pygathrix nigripes'' * Gray-shanked douc, ''Pygathrix cinerea'' Even though they are known as "douc langurs", they are in fact more closely related to the proboscis monkey and snub-nosed monkeys than to any of the langurs.

Ecoregions Of Vietnam
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. Sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indomalayan Ecoregions
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 ...

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier ...

Phou Hin Poun National Biodiversity Conservation Area
The Phou Hin Poun National Biodiversity Conservation Area, formerly known as the Khammouane Limestone National Biodiversity Conservation Area, is one of 21 National Biodiversity Conservation Areas of the Lao People's Democratic Republic. Located in a limestone tower karst region of the Annamite Range in Khammouane Province, it is home to a number of rare or newly discovered species. National Biodiversity Conservation Areas are not protected by the government of Laos in any meaningful way; the budget for each is about $500. The human population of the NBCA is 29,603. Flora and fauna The vegetation of Phou Hin Poun National Biodiversity Conservation Area is shaped by its tropical savanna climate, and the rugged, cave-riddled and porous karst terrain. Over 50% of the landscape is estimated to be rocky outcroppings, and most of the rest is dry evergreen forest and scrubland. This diverse landscape is home to 113 species of mammal, 160 species of bird, 81 species of reptile, 47 speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dipterocarp
Dipterocarpaceae is a family of 16 genera and about 695 known species of mainly tropical lowland rainforest trees. The family name, from the type genus ''Dipterocarpus'', is derived from Greek (''di'' = two, ''pteron'' = wing and ''karpos'' = fruit) and refers to the two-winged fruit. The largest genera are ''Shorea'' (196 species), ''Hopea'' (104 species), ''Dipterocarpus'' (70 species), and ''Vatica'' (65 species).Ashton, P.S. Dipterocarpaceae.

Nam Kading National Protected Area is a national protected area in Bolikhamsai Province in central Laos. This rugged and largely inaccessible park, cut through by its namesake Nam Kading river, is home to a wide variety of plant and animal species, some endangered. Due to its ruggedness, the park lacks any significant human settlement.

Capricornis Sumatraensis
The mainland serow (''Capricornis sumatraensis'') is a serow species native to the Himalayas, Southeast Asia and China. The mainland serow is related closely to the red serow, Himalayan serow, Sumatran serow, and the Chinese serow (''C. milneedwardsii)''. Taxonomy In 1831, Brian Houghton Hodgson first described a goat-like animal with short annulated horns occurring in montane regions between the Sutlej and Teesta Rivers under the name "Bubaline Antelope". As "Bubaline" was preoccupied, he gave it the scientific name ''Antelope thar'' a few months later. When William Ogilby described the genus '' Capricornis'' in 1838, he determined the Himalayan serow as type species of this genus. Teeth from ''C. sumatraensis'' were found in a dig from Khok Sung, estimated to originate from the Middle Pleistocene. Characteristics The mainland serow possesses guard hairs on its coat that are bristly or coarse and cover the layer of fur closest to its skin to varying degrees. The animal ...
