History of the Steppe Introduction Geography. The Steppe (aka the Eurasian Steppe) is a vast strip of land stretching from Ukraine to Mongolia. The term steppe denotes grassland: a low-precipitation region with enough rain for grass, but not enough for trees (see Climates and Biomes).
A steppe climate is found in the middle of continents and in the lee of high mountains. The mountains block moist air from oceans or tropical climates from reaching the steppe. There is not enough precipitation for trees to grow except by rivers.
