Amur Meadow Steppe
The Amur meadow steppe ecoregion (WWF ID: PA0901) is spread over two sections of the middle Amur River valley in the Russian Far East. The terrain is one of flat floodplains on alluvial soil. Due to high water table and frequent flooding, the area has remained relatively forest-free, and is today characterized by extensive wetlands of bogs and grasslands. The area remained ice-free during the Pleistocene glaciation, creating a refuge for many plant and animal species. It has an area of . Location and description The northern section stretches about 300 km in a northwest-to-southeast direction on the Russian side of the south-flowing Amur River. it is roughly centered on the city of Blagoveshchensk in Amur Oblast, Russia. This section is mostly surrounded by higher ground in the Manchurian mixed forests ecoregion. Separated by 150 km, the southern section is about 100 km longer, and straddles the Amur as it turns northeast between Heilongjiang province in Ch ...

Bolshekhekhtsirsky Nature Reserve
Bolshekhekhtsirsky Nature Reserve () (Big Khekhtsir) is a Russian 'zapovednik' (strict ecological reserve) covering and named for the Big Khekhtsir Ridge, about 20 km south of the city of Khabarovsk, in the Russian Far East. The area is noteworthy for its position - close to a city and relatively open to public hikers on certain trails - and for being an island of mountain-forest biodiversity surrounded by lower river floodplains. The reserve is situated in the Khabarovsk Krai. The reserve was created in 1963, and covers an area of . Topography The Khetskir Ridge is an "island ridge" covered in coniferous forest, surrounded on all sides by low flatlands of the Amur River, which runs west-to-east to the north of the ridge, the lower reaches of the Ussuri River, which runs to the west of the reserve before meeting the Amur, and the Cirka River, which wraps around the ridge on its east, south and west sides. About 20 km of the reserve's western border faces China acro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Khingan Nature Reserve
Khingan Nature Reserve ( ''Khinganskiy zapavyednik'') (also Khingansky) is a Russian 'zapovednik' (strict nature reserve), located in the extreme south-east of the Amur River region of the Russian Far East. The reserve covers two types of habitat: the flat Arkharinskaya lowlands with abundant wetlands, and forested spurs of the Lesser Khingan mountains. In particular, Khingan Reserve was created to protect steppe and forest-steppe landscapes, and nesting sites of the endangered Red-crowned crane (Ussuri crane) and the vulnerable White-naped crane. The reserve is situated in the Arkharinsky District of Amur Oblast. Topography The Khingan Nature reserve is divided into two separate sections, one on the Amur-Zeya-Bureya intermountain plains (about 70% of the area), and one in the low rugged hills of the left bank of the Amur River (70% of the area). The lowlands are Quaternary lakes and rivers of alluvial and sedimentary rocks. The mountain section averages 200–400 meters in ...

Rosaceae
Rosaceae (), the rose family, is a family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus '' Rosa''. The family includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere. Many economically important products come from the Rosaceae, including various edible fruits, such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, blackberries, loquats, strawberries, rose hips, hawthorns, and almonds. The family also includes popular ornamental trees and shrubs, such as roses, meadowsweets, rowans, firethorns, and photinias. Among the most species-rich genera in the family are '' Alchemilla'' (270), '' Sorbus'' (260), ''Crataegus'' (260), '' Cotoneaster'' (260), '' Rubus'' (250), and ''Prunus'' (200), which contains the plums, cherries, peaches, apricots, and almonds.

Calamagrostis
''Calamagrostis'' (reed grass or smallweed) is a genus of flowering plants in the grass family Poaceae, with about 260 species that occur mainly in temperate regions of the globe. Towards equatorial latitudes, species of ''Calamagrostis'' generally occur at higher elevations. These tufted perennials usually have hairless narrow leaves. The ligules are usually blunt. The inflorescence forms a panicle. Some may be reed-like. The plants may be rhizomatous (underground stems with shoots), stoloniferous (with runners), or caespitose (growing in tufts or clumps). The bisexual spikelets have a single floret and generally they are purple or purple-brown. The spikelets are clustered into inflorescences, which usually develop in early- to mid-summer on long culms ( = stems). Many species of ''Calamagrostis'' are morphologically similar, but they generally occur in distinct habitats, and they have unique geographical distributions. Given the subtle distinctions between many closely related ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wet Meadow
A wet meadow is a type of wetland with soils that are Solubility, saturated for part or all of the growing season which prevents the growth of trees and brush. Debate exists whether a wet meadow is a type of marsh or a completely separate type of wetland. Wet prairies and wet savannas are hydrologically similar. Hydrology and ecology Wet meadows may occur because of restricted drainage or the receipt of large amounts of water from rain or melted snow. They may also occur in riparian zones and around the shores of large lakes. Unlike a marsh or swamp, a wet meadow does not have standing water present except for brief to moderate periods during the growing season. Instead, the ground in a wet meadow fluctuates between brief periods of Flood, inundation and longer periods of Hydric soil, saturation. Wet meadows often have large numbers of wetland plant species, which frequently survive as buried seeds during dry periods, and then regenerate after flooding. Wet meadows therefore do ...

Humid Continental Climate
A humid continental climate is a climatic region defined by Russo-German climatologist Wladimir Köppen in 1900, typified by four distinct seasons and large seasonal temperature differences, with warm to hot (and often humid) summers, and cold (sometimes severely cold in the northern areas) and snowy winters. Precipitation is usually distributed throughout the year, but often these regions do have dry seasons. The definition of this climate in terms of temperature is as follows: the mean temperature of the coldest month must be below or depending on the isotherm, and there must be at least four months whose mean temperatures are at or above . In addition, the location in question must not be semi-arid or arid. The cooler ''Dfb'', ''Dwb'', and ''Dsb'' subtypes are also known as hemiboreal climates. Although amount of snowfall is not a factor used in defining the humid continental climate, snow during the winter in this type of climate is almost a guarantee, either intermitte ...
