grassland

n. area of land mainly covered with grasses (i.e. prairie); area of land where grass is grown (especially pastureland)

Grasslands are areas where the vegetation is dominated by grasses (Poaceae) and other herbaceous (non-woody) plants (forbs). Grasslands occur naturally on all continents except Antarctica, and in many other areas they have replaced the natural vegetation due to human influence. Grassland vegetation varies from that dominated solely by herbaceous species to that in which woody plants also occur and trees may be co-dominant with the grasses. In temperate latitudes, such as north-west Europe, grasslands are dominated by perennial species, whereas in warmer climates annual species form a greater component of the vegetation. Grasslands are very varied and can be found in most terrestrial climates. Grassland vegetation can vary in height from very short, as in chalk downland where the vegetation may be less than 30 cm high, to quite tall, as in the case of North American tallgrass prairie, South American grasslands and African savannah. Grassland, shrubland and desert environments cover two-thirds of the world's land surface . In countries where modern agriculture has not destroyed wild grasslands, the greatest diversity of grazing animals and predators on the planet calls these open habitats their home. Grassland habitats appeared on Earth some 70 or 80 million years ago.
