The Info List - Steppe

--- Advertisement ---

In physical geography, a steppe (Russian: степь, IPA: [stʲepʲ]) is an ecoregion, in the montane grasslands and shrublands and temperate grasslands, savannas and shrublands biomes, characterized by grassland plains without trees apart from those near rivers and lakes. In South Africa, they are referred to as veld. The prairie of North America
North America
(especially the shortgrass and mixed prairie) is an example of a steppe, though it is not usually called such. A steppe may be semi-desert or covered with grass or shrubs or both, depending on the season and latitude. The term is also used to denote the climate encountered in regions too dry to support a forest but not dry enough to be a desert. The soil is typically of chernozem type. Steppes are usually characterized by a semi-arid and continental climate. Extremes can be recorded in the summer of up to 45 °C (113 °F) and in winter, −55 °C (−67 °F). Besides this huge difference between summer and winter, the differences between day and night are also very great. In the highlands of Mongolia, 30 °C (86 °F) can be reached during the day with sub-zero °C (sub 32 °F) readings at night.

in Russia

The mid-latitude steppes can be summarized by hot summers and cold winters, averaging 250–510 mm (10–20 in) of precipitation per year. Precipitation level alone is not what defines a steppe climate; potential evapotranspiration must also be taken into account.

Two types[edit]

Two types of steppe can be recorded:[1]

steppe: the "true" steppe, found in continental areas of the world; they can be further subdivided, as in the Rocky Mountains Steppes[1] Subtropical
steppe: a similar association of plants that can be found in the driest areas with a Mediterranean-like climate; it usually has a short wet period

Peculiar types of steppe include shrub-steppe and alpine-steppe. The Eurasian Grass- Steppe
of the temperate grasslands, savannas, and shrublands had a role in the spread of the horse, the wheel, and the Indo-European languages. The Indo-European expansion and diverse invasions of horse archer civilizations of the steppe eventually led to, e.g., the rise of Mycenaean Greece
Mycenaean Greece
by amalgamation of Indo-Europeans with the autochthonous pre-Greek population and also its destruction during the Dorian invasion
Dorian invasion
in the Late Bronze Age collapse, followed by the demise of the Achaeans, the spread of the Sea Peoples, and eventually the rise of Archaic and ultimately Classical Greece. Locations[edit]

The world's largest steppe region, often referred to as "the Great Steppe", is found in Eastern Europe
Eastern Europe
and Central Asia, and neighbouring countries stretching from Ukraine
in the west through Russia, Kazakhstan, China, Turkmenistan
and Uzbekistan
to the Altai, Koppet Dag and Tian Shan

ranges. The inner parts of Anatolia
in Turkey, Central Anatolia
and East Anatolia
in particular and also some parts of Southeast Anatolia, as well as much of Armenia
and Iran
are largely dominated by cold steppe. The Pannonian Plain
is another steppe region in eastern Europe, primarily Hungary.

Another large steppe area (prairie) is located in the central United States, western Canada and northern part of Mexico. The shortgrass prairie steppe is the westernmost part of the Great Plains

region. The Channeled Scablands

and much of the high elevation regions east of the southern Andes. Relatively small steppe areas can be found in the interior of the South Island

steppe[edit] In Europe, some Mediterranean areas have a steppe-like vegetation, such as central Sicily
in Italy, southern Portugal, parts of Greece
in the southern Athens
area,[2] and central-eastern Spain, especially the southeastern coast (around Murcia), and places cut off from adequate moisture due to rain shadow effects such as Zaragoza. In Asia, a subtropical steppe can be found in semi-arid lands that fringe the Thar Desert
of the Indian subcontinent

and the Badia of the Arabian peninsula. In Australia, "subtropical steppe" can be found in a belt surrounding the most severe deserts of the continent and around the Musgrave Ranges. In North America
