Natural vegetation in plains can include prairies/grasslands, forests, savanah, tundra, and desert biomes, among others. Plains occur as lowlands along valleys or at the base of mountains, as coastal plains, and as plateaus or uplands. Plains are one of the major landforms on earth, being present on all continents and covering more than one-third of the world
