Because of the low annual precipitation
, temperate grasslands have very few trees. Grasses are the dominant vegetation; their roots and rhizomes provide increased fertility to the soil. Fires caused by lightening occur often in grasslands; without fires grasslands are converted to scrub forests.

The weather is moderate
, and there are no trees to move to create large, open fields. The very small hills on the prairie are called pimples, and they usually don’t rise taller than 1.5 meters (4 feet). The prairie grasses hold the soil firmly in place, so soil erosion is minimal.
Why are there no trees in steppes?
Steppes are semi-arid, meaning they receive 25 to 50 centimeters (10-20 inches) of rain each year. This is enough rain to support short grasses, but not enough for tall grasses or
trees
to grow.
