Why do grasslands have very few bushes and trees?

Why are there no trees in the 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. Grass recovers quickly from the fire – however, trees do not. This partially explains the absence of trees in the area.
