Da Hinggan–Dzhagdy Mountains Conifer Forests
The Da Hinggan-Dzhagdy Mountains conifer forests ecoregion (WWF ID: PA0505) covers the Greater Khingan Mountains of Northeast China, and across the border north into the Russian Far East where it follows the mountain ridge for another 500 km to the east. The mountain forests exhibit a floral community called "Daurian flora", a combination of the Siberian taiga to the north and the Manchurian floral types to the south. The eastern slopes are steep and drained by many rivers, the western slopes are gentler, and there are grasslands on some slopes. The ecoregion is in the Palearctic realm, with a subarctic climate. It covers . Location and description The ecoregion covers the Greater Khingan mountains in Northeast China and crosses the Amur River north into the Dzhagdy in Russia. In China, this is in the northern parts of Inner Mongolia Autonomous Region and Heilongjiang Province. In Russia, most of the region is in Amur Oblast. Climate Because of its altitude and dista ...

Palearctic Realm
The Palearctic or Palaearctic is a biogeographic realm of the Earth, the largest of eight. Confined almost entirely to the Eastern Hemisphere, it stretches across Europe and Asia, north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Mediterranean Basin; North Africa; North Arabia; Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. Both the eastern and westernmost extremes of the Paleartic span into the Western Hemisphere, including Cape Dezhnyov in Chukotka Autonomous Okrug to the east and Iceland to the west. The term 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/ Indom ...

Larix Gmelinii
''Larix gmelinii'', the Dahurian larch or East Siberian larch, is a species of larch native to eastern Siberia and adjacent northeastern Mongolia, northeastern China (Heilongjiang), South Korea and North Korea. Description ''Larix gmelinii'' is a medium-sized deciduous coniferous tree reaching 10–30 m tall, rarely 40 m, with a trunk up to 1 m diameter. The crown is broad conic; both the main branches and the side branches are level, the side branches only rarely drooping. The shoots are dimorphic, with growth divided into long shoots (typically 5–30 cm long) and bearing several buds, and short shoots only 1–2 mm long with only a single bud. The leaves are needle-like, light green, 2–3 cm long; they turn bright yellow to orange before they fall in the autumn, leaving the variably downy reddish-brown shoots bare until the next spring. The cones are erect, ovoid, 1–2 cm (rarely to 2.5 cm; but 2–4 cm in var. ''principis-rupprechtii'') lon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zeya River
The Zeya (; from indigenous Evenki word "djee" (blade); zh, 结雅; mnc, m= , Mölendroff: jingkiri bira) is a northern, left tributary of the Amur in Amur Oblast, Russia. It is long, and has a drainage basin of . The average flow of the river is . History The first Russian documented to enter the area was Vassili Poyarkov. Course It rises in the Toko-Stanovik mountain ridge, a part of the Stanovoy Range. The Zeya flows through the Zeya Reservoir, at the junction of the Tukuringra Range and Dzhagdy Range, and joins the Amur near Blagoveshchensk, at the border with China. Regulation of river discharge by Zeya Dam mitigates extremities of river flow down to 5000 m³/s. The Zeya contributes around 16% of both the average and maximum flow of de Amur because of the flow regulations. In the past, the Zeya could have contributed up to almost 50% of the Amur's maximum flow of approximately 30,000 m³/s. The main tributaries of the Zeya are Tok, Mulmuga, Bryanta, Gilyuy, a ...

Nora River
Nora River is a waterway in the north of Spain, a tributary of the Nalón (river), Nalón River that flows through Asturias. It is one of the longest tributaries of Asturias. Beginning in Valvidares, Sariego, it continues through the concejos of Siero and Noreña. In its final kilometers, it serves as a natural border between Oviedo and Llanera, Asturias, Llanera first, and between Oviedo and Las Regueras later. It is located between Priañes (Oviedo), Santa María de Grado (Grado, Asturias, Grado) and Tahoces (Las Regueras). Near its outlet, the landscape is beautiful. The dam of the Priañes reservoir and the hydroelectric power station of the same name are owned by HC Energía. Sofoxo is a cave on the river's right bank; it was discovered by Count de la Vega del Sella. The Roman bridge, Puente del Romanon, spans the river at Pola de Siero, east of Oviedo.

Zapovednik
A zapovednik is an established term on the Post-Soviet states, territory of the former Soviet Union for a protected area which is kept "forever wild". It is the highest degree of environmental protection for the assigned areas, which are strictly protected. Access to the public is restricted. Overview The literal English translation of ''zapovednik'' is "nature sanctuary" (like animal sanctuary); however, in practice, zapovedniks sometimes have to do with the protection of things other than nature and can incorporate historical-cultural, historical–archaeological, and other types of cultural or natural heritage. They also function as important sites for historical research and education and so are comparable to the Site of Special Scientific Interest, Sites of Special Scientific Interest as found in the United Kingdom and Site of Special Scientific Interest (Hong Kong), Hong Kong. The term ''zapovednik'', which refers to the reserve, staff and infrastructure, was used in the for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nora Nature Reserve
Nora Nature Reserve () (also Norsky) is a Russian 'zapovednik' (strict nature reserve) on the northeastern part of the Amur- Zeya lowland plain between the Nora River and the Selemdzha River. The reserve is known for its herd of Norsk roe deer, the largest migrating herd in the world, with 5,000-7,000 individuals migrating through every September. The terrain is half forested, and half wetland and bogs, in the meeting zone between Siberian, Okhotsk, and Mongolian plant and animal communities. The reserve is situated in the Selemdzhinsky District of Amur Oblast. Topography The Nora Reserve is roughly triangular shaped, 50 km west-to-east across the base, and 70 km north-to-south. The western border follows the meandering Nora River (running north to south at this point), while the southern border follows the northern edge of the floodplain of the Selemdzha River (running east to west towards the Zeya River).

Birch
A birch is a thin-leaved deciduous hardwood tree of the genus ''Betula'' (), in the family Betulaceae, which also includes alders, hazels, and hornbeams. It is closely related to the beech- oak family Fagaceae. The genus ''Betula'' contains 30 to 60 known taxa of which 11 are on the IUCN 2011 Red List of Threatened Species. They are typically short-lived pioneer species and are widespread in the Northern Hemisphere, particularly in northern areas of temperate climates and in boreal climates. Birch wood is used for a wide range of purposes. Description Birch species are generally small to medium-sized trees or shrubs, mostly of northern temperate and boreal climates. The simple leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate. They often appear in pairs, but these pairs are really borne on spur-like, two-leaved, lateral branchlets. The fruit is a small samara, although the wings may be obscure in some species. They differ from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alder
Alders are trees of the genus ''Alnus'' in the birch family Betulaceae. The genus includes about 35 species of monoecious trees and shrubs, a few reaching a large size, distributed throughout the north temperate zone with a few species extending into Central America, as well as the northern and southern Andes. Description With a few exceptions, alders are deciduous, and the leaves are alternate, simple, and serrated. The flowers are catkins with elongate male catkins on the same plant as shorter female catkins, often before leaves appear; they are mainly wind-pollinated, but also visited by bees to a small extent. These trees differ from the birches (''Betula'', another genus in the family) in that the female catkins are woody and do not disintegrate at maturity, opening to release the seeds in a similar manner to many conifer cones. The largest species are red alder (''A. rubra'') on the west coast of North America, and black alder (''A. glutinosa''), native to ...

Hazel
Hazels are plants of the genus ''Corylus'' of deciduous trees and large shrubs native to the temperate Northern Hemisphere. The genus is usually placed in the birch family, Betulaceae,Germplasmgobills Information Network''Corylus''Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins .Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan . though some botanists split the hazels (with the hornbeams and allied genera) into a separate family Corylaceae. The fruit of the hazel is the hazelnut. Hazels have simple, rounded leaves with double-serrate margins. The flowers are produced very early in spring before the leaves, and are monoecious, with single-sex catkins. The male catkins are pale yellow and long, and the female ones are very small and largely concealed in the buds, with only the bright-red, 1-to-3 mm-long styles visible. The fruits are nuts long and 1–2 cm diameter, surrounded by an involucre (husk) which partly to fully encloses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
