Changbai Mountains Mixed Forests
The Changbai Mountains mixed forests ecoregion (WWF ID: PA0414) covers the Changbai Mountains and surrounding foothills in China and North Korea. The region features extensive and naturally preserved deciduous and conifer forests. The region exhibits high biodiversity due to its relative isolation, temperate climate with high rainfall, and centrality to central Chinese, Siberian, and European floral communities. In 1979, a significant portion of the ecoregion was designated the Changbaishan Man and the Biosphere Programme, Biosphere Reserve by UNESCO. Location and description The Changbai Mountains area ranges across the foothills and higher elevations of a volcanic plateau on the north of the Korean peninsula, straddling the border between China and North Korea. The region is surrounded by the lower terrain of the Manchurian mixed forests ecoregion, but is centered on the volcanic crater of Paektu Mountain. Climate The climate of the Changbai ecoregion is ''Humid contin ... [...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 ...

Tilia
''Tilia'' is a genus of about 30 species of trees or bushes, native throughout most of the temperateness, temperate Northern Hemisphere. The tree is known as linden for the European species, and basswood for North American species. In Britain and Ireland they are commonly called lime trees, although they are not related to the citrus Lime (fruit), lime. The genus occurs in Europe and eastern North America, but the greatest species diversity is found in Asia. Under the Cronquist system, Cronquist classification system, this genus was placed in the family Tiliaceae, but genetic research summarised by the Angiosperm Phylogeny Group has resulted in the incorporation of this genus, and of most of the previous family, into the Malvaceae. ''Tilia'' species are mostly large, deciduous trees, reaching typically tall, with oblique-cordate (heart-shaped) leaves across. As with elms, the exact number of species is uncertain, as many of the species can Hybrid (biology), hybridise readily, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ecoregions Of North Korea
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] |

Picea Jezoensis
''Picea jezoensis'' (sometimes misspelled ''Picea yezoensis''), the dark-bark spruce, Ezo spruce, Yezo spruce, or Jezo spruce, is a large evergreen tree growing to 30–50 m tall and with a trunk diameter of up to 2 m. It is native to northeast Asia, from the mountains of central Japan and the Changbai Mountains on the China-North Korea border, north to eastern Siberia, including the Sikhote-Alin, Kuril Islands, Sakhalin and Kamchatka. It is found in cold but humid temperate rain forests, and nowhere does its range extend more than 400 km from the Pacific Ocean. The specific epithet ''jezoensis'' derives from Ezo, an old name for Hokkaido and other islands north of the Japanese island of Honshu, where the species is found. The bark is thin and scaly, becoming fissured in old trees. The crown is broad conic. The shoots are pale buff-brown, glabrous (hairless) but with prominent pulvini.

Abies Holophylla
''Abies holophylla'', also called needle fir or Manchurian fir, is a species of fir native to mountainous regions of northern Korea, southern Ussuriland, and China in the provinces of Heilongjiang, Jilin, and Liaoning. It is an evergreen coniferous tree growing to tall and in trunk diameter with a narrowly conical crown of horizontal spreading branches. The bark is scaly and gray-brown with resin blisters. The leaves ("needles") are flattened, long and thick, spread at right angles from the shoot, and end in a point. They spread on two sides, but not flat like for example in silver fir. Usually they more or less rise up forming with the shoot a V-shape empty compartment above it. Unlike in silver fir, the leaves here are sharp and prickly, without any indentation at the top. They are bright green above and whitish-green below with 2 whitish strips, each of which is formed by 7–10 wax-covered stomatal bands. The shoots are glabrous, shiny yellow-gray when young and tu ...
