The Eurasian Steppe is separated into three sections: the
Carpathian Basin, the contiguous stretch of some 2,500 miles of grassland that stretches from the
mouth of the Danube in
Romania to the
Altai Mountains on the
China-Russia Border, and the
Mongolian Plateau. The steppe is criss-crossed by mountain ranges that historically did not hinder the movement of nomads.
Pannonian Steppe The
Pannonian Steppe, or Peri-Carpathian Steppe, is the westernmost part of the Eurasian Steppe, separated from the Pontic-Caspian Steppe by the
Carpathian Mountains. It encompasses most of Hungary and parts of southern Slovakia, western Romania, northern Bulgaria, northern Serbia, and eastern Austria. File:Hortobagy-ziehbrunnen.jpg|A draw well in

Pontic–Caspian Steppe The
Pontic–Caspian Steppe is the main
European end of the Eurasian Steppe and begins near the mouth of the
Danube, stretching northeast almost to
Kazan and then southeast to the southern tip of the
Ural Mountains. Its northern edge was a broad band of
forest steppe which has now been obliterated by the conversion of the whole area to agricultural land. In the southeast the Black Sea–Caspian Steppe extends between the
Black Sea and
Caspian Sea to the
Caucasus Mountains. On the north shore of the Black Sea, the
Crimean Peninsula has some interior steppe and ports on the south coast which link the steppe to the civilizations of the Mediterranean basin. File:Філія ЛПЗ НАНУ "Стрільцівський степ" Stipa tirsa (ЧКУ).jpg|The

Ural–Caspian Narrowing The steppe narrows around the southern end of the
Ural Mountains, about 650 km (400 mi) northeast of the
Caspian Sea, forming the Ural-Caspian Narrowing, that joins the Pontic-Caspian Steppe in Europe with the
Kazakh Steppe in
Central Asia. File:Гуси на Нугушском водохранилище.jpg|

Kazakh Steppe The
Kazakh Steppe makes up most of the Eurasian Steppe in Central Asia. It extends from the
Urals to
Dzungaria. To the south, it grades off into semi-desert and desert which is interrupted by two great rivers, the
Amu Darya (Oxus) and
Syr Darya (Jaxartes), which flow northwest into the
Aral Sea and provide irrigation for agriculture. In the southeast is the densely populated
Fergana Valley and west of it the great oasis cities of
Tashkent,
Samarkand and
Bukhara along the
Zeravshan River. The southern area has a complex history (see
Central Asia and
Greater Iran), while in the north, the Kazakh Steppe proper was relatively isolated from the main currents of
written history. File:Astana-steppe-7748.jpg|The steppe in

Dzungarian Narrowing Along the former
Sino-Soviet border, mountains extend north almost to the forest zone, separating the Central Steppe from the Eastern Steppe, leaving only limited grassland in
Dzungaria. This discontinuous section of the Eurasian steppe connects the great steppes of
Central Asia and
East Asia. The east-west
Tian Shan Mountains divide the steppe into Dzungaria in the north and the Tarim Basin to the south.
Dzungaria is bounded by the
Tarbagatai Mountains on the west and the
Mongolian
Altai Mountains on the east, neither of which is a significant barrier. Dzungaria has good grassland around the edges and a central desert. It often behaved as a westward extension of Mongolia and connected Mongolia to the Kazakh Steppe. To the north of Dzungaria are mountains and the Siberian forest. To the south and west of Dzungaria, and separated from it by the
Tian Shan mountains, is an area about twice the size of Dzungaria, the oval
Tarim Basin. The Tarim Basin's arid conditions make it unsuitable for sustaining a nomadic population. However, along its periphery, rivers descend from the mountains, creating a circle of cities that thrived on irrigation agriculture and engaged in east-west trade. The Tarim Basin formed an island of near civilization in the center of the steppe. The
Northern Silk Road went along the north and south sides of the Tarim Basin and then crossed the mountains west to the
Fergana Valley. At the west end of the basin the
Pamir Mountains connect the Tian Shan Mountains to the
Himalayas. To the south, the
Kunlun Mountains separate the Tarim Basin from the thinly peopled
Tibetan Plateau. File:Тувинские просторы.jpg|

Mongolian-Manchurian Steppe The
Mongolian-Manchurian Steppe is the main part of the Eurasian Steppe in East Asia. It covers large parts of
Mongolia and the Chinese province of
Inner Mongolia. The two are separated by a relatively dry area marked by the
Gobi Desert. South of the Mongol Steppe is the high and thinly peopled
Tibetan Plateau. The northern edge of the plateau is the
Gansu or
Hexi Corridor, a belt of moderately dense population that connects
China proper with the
Tarim Basin. The
Hexi Corridor was the main route of the
Silk Road. In the southeast the Silk Road led over some hills to the east-flowing
Wei River valley which led to the
North China Plain. South of the Khingan Mountains and north of the
Taihang Mountains, the Mongolian-Manchurian steppe extends east into Manchuria as the Liao Xi steppe. In Manchuria, the steppe grades off into forest and mountains without reaching the Pacific. The central area of forest-steppe was inhabited by pastoral and agricultural peoples, while to the north and east was a thin population of hunting tribes of the Siberian type.

Fauna Big mammals of the Eurasian steppe were
Przewalski's horse, the
saiga antelope, the
Mongolian gazelle, the
goitered gazelle, the
wild Bactrian camel and the
onager. The
gray wolf,
corsac fox,
Pallas's cat and occasionally the
brown bear are predators roaming the steppe. Smaller mammal species are the
Mongolian gerbil, the
little souslik and the
bobak marmot. Furthermore, the Eurasian steppe is home to a great variety of bird species. Threatened bird species living there are for example the
imperial eagle, the
lesser kestrel, the
great bustard, the
pale-back pigeon and the
white-throated bushchat. File:Przewalski mongolie.jpg|

Onager The primary domesticated animals raised were sheep and goats with fewer cattle than one might expect.
Camels were used in the drier areas for transport as far west as
Astrakhan. There were some
yaks along the edge of
Tibet. The horse was used for transportation and warfare.
The horse was first domesticated on the Pontic–Caspian or Kazakh steppe sometime before 3000 BC, but it took a long time for
mounted archery to develop and the process is not fully understood. The
stirrup does not seem to have been completely developed until 300 AD (see
Stirrup,
Saddle,
Composite bow,
Domestication of the horse and related articles).
Flora The steppe is dominated by shrubs and grasses, with only a small amount of trees. The grass communities are primarily C3 and
C4 grasses. Common genera include
Stipa and
Festuca. Grasses from the Stipa genus include needlegrass (Stipa krylovii), Stipa korshinskyi, and
lessing feather grass (Stipa lessingiana). In addition to grasses, two species of
sagebrush or
wormwood,
Artemisia austriaca and Artemisia nitrosa, are commonly found throughout the steppe.
Ecoregions The
World Wide Fund for Nature divides the Eurasian steppe's temperate
grasslands,
savannas and
shrublands into a number of
ecoregions, distinguished by elevation, climate, rainfall, and other characteristics and home to distinct animal and
plant communities and species and distinct
habitat ecosystems. •
