The Grassland Biome
The grassland biome is the characteristic community of animals and plants found in the world's grasslands. Grasslands are regions on Earth in which the dominant plants are grasses. Grasslands are found on every continent except Antarctica, and in total cover between 30 and 40% of Earth's land area. With trees either sparse or absent, grasslands are wide open places that experience low rainfall. They are typically inhabited by grazing animals, whose presence helps keep tree growth to a minimum.
