the Steppe Extent of the Eurasian steppes.

A typical steppe is a semiarid environment that generally receives between 25 and 30 centimeters (10 to 12 inches) of rainfall per year.1

Because the steppe is a vast geographical area, precipitation levels can vary based on specific regional conditions:

  • General Range: While the standard classification often cites 25 to 30 cm, some areas of the Eurasian Steppe may support sparse grass with annual rainfall between 10 and 20 inches (250 and 500 millimeters), as lower temperatures in certain regions can reduce evaporation and help retain soil moisture.2
  • Climatic Context: Rainfall is a critical factor in defining the steppe; it is high enough to support grassland but low enough to prevent the growth of forests, while remaining wetter than a true desert.1
  • Regional Variability: Precipitation tends to become more erratic moving eastward across the Eurasian Steppe, making western regions like Ukraine better suited for natural pastureland than those further east.2
