The Semi-arid Pampas, also known as the Dry Pampas, is a temperate grassland ecoregion of central Argentina. The Semi-arid Pampas cover an area of 327,000 square kilometers (126,300 square miles), including western Buenos Aires Province, southern Cordoba and San Luis Provinces and most of La Pampa Province. The area is, in all, home to no more than a million people, who generally enjoy some of the nation's lowest poverty rates. The Humid Pampas grassland lies to the east, while the drier Argentine Espinál (thorny) grassland lies to the west.
