Suiphun–Khanka Meadows And Forest Meadows
The Suiphun–Khanka meadows and forest meadows ecoregion (WWF ID: PA0907) (also: Ussuri-Wusuli meadow and forest meadow) is a relatively small ecoregion centered on Lake Khanka, a fresh water lake in the Russian Far East, with a portion in China. The terrain is unforested, flat, and marshy. The area is an important stopover spot for migratory birds, including many vulnerable species. It has an area of , and is in the Flooded grasslands and savannas biome. Location and description The headwaters of the Ussuri River cross the northern edge of the ecoregion, Lake Khanka dominates the middle, and the Suifen River ( Razdolnaya River in Russian) feeds the lake from the south. The lake straddles the border between Heilongjiang Province in China to the west, and Primorsky Krai in Russia to the east. The only outflow from Lake Khanka is the Songacha River, a tributary of the Ussuri, and eventually the Amur River. The entire area is known as the Khanka Depression, as it is ...

Flooded Grasslands And Savannas
Flooded grasslands and savannas is a terrestrial biome of the WWF biogeographical system, consisting of large expanses or complexes of flooded grasslands. These areas support numerous plants and animals adapted to the unique hydrologic regimes and soil conditions. Large congregations of migratory and resident waterbirds may be found in these regions. However, the relative importance of these habitat types for these birds as well as more vagile taxa typically varies as the availability of water and productivity annually and seasonally shifts among complexes of smaller and larger wetlands throughout a region. This habitat type is found on four of the continents on Earth. Some globally outstanding flooded savannas and grasslands occur in the Everglades, Pantanal, Lake Chad flooded savanna, Zambezian flooded grasslands, and the Sudd. The Everglades, with an area of , are the world's largest rain-fed flooded grassland on a limestone substrate, and feature some 11,000 species of ...

Xingkai Lake National Nature Reserve
Lake Khanka (russian: о́зеро Ха́нка) or Lake Xingkai (), is a freshwater lake on the border between Primorsky Krai, Russia and Heilongjiang province, Northeast China (at ). Etymology On the Delisle map of 1706, the lake is named ''Himgon'' and from it flows a river labelled with the names ''Usurou'' and ''Ousuri''. On the 1739 map of Johann Matthias Hase, the lake is named Lake ''Hinka'' and the river flowing from it called by the names ''Ousoury'' and '' Schur''. On the 1752 map of d'Anville, the lake is named ''Hink'', and the river from it is called '' Songhachan'', which flows, in turn, into the river ''Usuri''. On an 18th-century map showing the "Irkutsk governorate with the adjacent islands and the western coast of America", the river issuing from ''Lake Hinka'' is named as the ''Usuri''. On the 1860 map attached to the Convention of Peking, two lakes are shown: the larger ''Oz. Khankai'' (Russian: "Lake Khankai"), with ''Khankai'' glossed as signi ...

Khanka Nature Reserve
Khanka Nature Reserve (russian: Ханкайский заповедник ''Khankaiskiy zapavyednik'') (also Khankaisky) is a Russian 'zapovednik' (strict nature reserve) that covers portions of the shore and waters of Lake Khanka, the largest freshwater lake in the Russian Far East. It is an important area for nesting and migrating waterfowl and other birds. The reserve is divided into five distinct sectors on the southern and eastern shores of the lake. The reserve is situated in the Spassky District, in the southwest of Primorsky Krai. It was formally established in 1990, and covers an area of . It is part of a UNESCO Biosphere Reserve. Topography The southern two-thirds of Khanka is in Russia; the northern third is in China. The total surface area of the lake is 4,190 km2. The Khanka Reserve is split into five sections that cover parts of the southern shore, the eastern shore, and a spur that extends from the northeast of the lake.

Red-crowned Crane
The red-crowned crane (''Grus japonensis''), also called the Manchurian crane or Japanese crane (; the Chinese character '丹' means 'red', '頂/顶' means 'crown' and '鶴/鹤' means 'crane'), is a large East Asian crane among the rarest cranes in the world. In some parts of its range, it is known as a symbol of luck, longevity, and fidelity. Description Adult red-crowned cranes are named for a patch of red bare skin on the crown, which becomes brighter during the mating season. Overall, they are snow white in color with black on the wing secondaries, which can appear almost like a black tail when the birds are standing, but the real tail feathers are actually white. Males are black on the cheeks, throat, and neck, while females are pearly gray in these spots. The bill is olive green to a greenish horn, the legs are slate to grayish black, and the iris is dark brown.Archibald G.W. & Meine, C.D. 1996. ''Family Gruidae (Cranes)''.

Wet Meadow
A wet meadow is a type of wetland with soils that are saturated for part or all of the growing season. 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. 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 inundation and longer periods of 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 not usually support aquatic life such as fish. They typically have a high diversity of plant speci ...

Peat
Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of , which is the average depth of the boreal orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. ''Sphagnum'' moss, also called peat moss, is one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mire
A mire, peatland, or quagmire is a wetland area dominated by living peat-forming plants. Mires arise because of incomplete decomposition of organic matter, usually litter from vegetation, due to water-logging and subsequent anoxia. All types of mires share the common characteristic of being saturated with water, at least seasonally with actively forming peat, while having their own ecosystem. Like coral reefs, mires are unusual landforms that derive mostly from biological rather than physical processes, and can take on characteristic shapes and surface patterning. A quagmire is a floating (quaking) mire, bog, or any peatland being in a stage of hydrosere or hydrarch (hydroseral) succession, resulting in pond-filling yields underfoot. Ombrotrophic types of quagmire may be called quaking bog (quivering bog). Minerotrophic types can be named with the term quagfen. There are four types of mire: bog, fen, marsh and swamp. A bog is a mire that, due to its location relative to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 freezing cold (sometimes severely cold in the northern areas) winters. Precipitation is usually distributed throughout the year but often do have dry seasons. The definition of this climate regarding 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. Humid continental climates are generally found between latitudes 30° N and 60° N, within the central and northeastern portions of North America, Europe, and Asia. They are rare and isolat ...

Manchurian Mixed Forests
The Manchurian mixed forests ecoregion (WWF ID: PA0426) covers the forested hills surrounding the river plains of northern China, Russia, North Korea, and South Korea. The ecoregion supports a number of rare species due to the relative isolation, the diversity of habitat, with mixed forests of deciduous Mongolian oak and conifers of Korean pine. Because mountains rise above the region on three sides, with plains and wetlands below, the area supports high biodiversity as a transition zone. Location and description The ecoregion occupies the middle-elevation slopes of three surrounding mountain ranges: the eastern slopes of the Greater Khingan Mountains, the southern slopes of the Lesser Khingan, and the western slopes of the Changbai Mountains. The southern section of the ecoregion surrounds the higher Changbai Mountains mixed forests ecoregion, while the middle section encircles most of the lower-elevation Northeast China Plain deciduous forests ecoregion, and the northern hal ...
