Steppe

In physical geography, a steppe () is an ecoregion characterized by grassland plains without trees except near rivers and lakes.Steppe biomes may include:

the montane grasslands and shrublands biome

the temperate grasslands, savannas and shrublands biomeA steppe may be semi-arid or covered with grass or with shrubs or with both, depending on the season and latitude. The term "steppe climate" denotes the climate encountered in regions too dry to support a forest but not dry enough to be a desert. Steppe soils are typically of the chernozem type.

Steppes are usually characterized by a semi-arid or continental climate. Extremes can be recorded in the summer of up to 45 °C (115 °F) and in winter, −55 °C (−65 °F). Besides this major seasonal difference, fluctuations between day and night are also very great. In both the highlands of Mongolia and northern Nevada, 30 °C (85 °F) can be reached during the day with sub-freezing readings at night.

Mid-latitude steppes feature hot summers and cold winters, averaging 250–510 mm (10–20 in) of precipitation per year. Precipitation level alone does not define a steppe climate; potential evapotranspiration also plays a role.
