Field Note

A grassland is an ecosystem where grasses and other small plants are common, while trees are scattered or scarce. In North America, many grasslands are called prairies. Rainfall is usually enough for grasses to grow, but not enough to support a dense forest. Some grasslands have wet seasons and dry seasons, and fires can occur naturally. Grass roots spread deep into the soil, helping plants reach water and holding soil in place. Bison graze on grasses, prairie dogs dig burrows, and coyotes may hunt small animals. Grasslands provide wildlife habitat, store carbon in their soils, and support people through grazing livestock and growing crops. Converting too much grassland to farms or buildings can reduce wildlife habitat and expose soil to erosion.
