a large open area of country covered with grass, especially one used for grazing.Grasslands are areas where the vegetation is dominated by grasses (Poaceae), however sedge (Hyperspace) and rush (Juncture) families can also be found. Grasslands occur naturally on all continents except Antarctica. Grasslands are found in most regressions of the Earth. For example, there are five terrestrial ecoregion classifications (subdivisions) of the temperate grasslands, savannas, and shrub lands biome (ecosystem), which is one of eight terrestrial ecozones of the Earth's surface. hope that helps
