In physical geography, a steppe (/ s t ɛ p /) is an ecoregion characterized by grassland plains without closed forests except near rivers and lakes. [1] Steppe biomes may include: the montane grasslands and shrublands biome; the tropical and subtropical grasslands, savannas, and shrublands biome; the temperate grasslands, savannas, and ...
The Eurasian Steppe, also called the Great Steppe or The Steppes, is the vast steppe ecoregion of Eurasia in the temperate grasslands, savannas and shrublands biome. It stretches through Hungary , Bulgaria , Romania , Moldova , Ukraine , southern Russia , Kazakhstan , Xinjiang , Mongolia and Manchuria , with one major exclave , the Pannonian ...
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes.
It is the transition ecoregion from the Great Plains prairie and steppe temperate grasslands in the south to the Taiga biome forests in the north. In central Asia the forest steppe ecotone is found in ecoregions in the mountains of the Iranian Plateau , in Iran , Afghanistan , and Balochistan .
The predominant vegetation in these biomes consists of grass and/or shrubs. The climate is temperate and ranges from semi-arid to semi-humid. The habitat type differs from tropical grasslands in the annual temperature regime and the types of species found here.
The forest-steppe is an area of Russia in which precipitation and evaporation are approximately equal. [2] The ecoregion is in the Palearctic realm, with a Humid Continental climate. According to one definition of its boundaries, it covers 727,269 km 2 (280,800 sq mi). [3]
A semi-arid desert or a steppe is a version of the arid desert with much more rainfall, vegetation and higher humidity. These regions feature a semi-arid climate and are less extreme than regular deserts. [ 34 ]
Woody plants, shrubs or trees may occur on some grasslands—forming savannas, scrubby grassland or semi-wooded grassland, such as the African savannas or the Iberian deheza. [ 17 ] As flowering plants and trees, grasses grow in great concentrations in climates where annual rainfall ranges between 500 and 900 mm (20 and 35 in). [ 18 ]
