Grasslands are big open spaces. There are not many bushes in the grassland. Trees are found only by rivers and streams. The grassland seems like an endless ocean of grass.

Grassland soil tends to be deep and fertile. The roots of perennial grasses usually penetrate far into the soil. In North America, the prairies were once inhabited by huge herds of bison and pronghorns who fed on the prairie grasses. These herds are almost gone now, and most of the prairies have been converted into the richest agricultural region on earth. Crops grow well in the rich soil.
