The Pampas, also called the Pampa are vast plains extending westward across central Argentina from the Atlantic coast to the Andean foothills, bounded by the Gran Chaco (north) and Patagonia (south). The name comes from a Quechua word meaning “flat surface.”

The Pampas have a gradual downward slope from northwest to southeast, from approximately 1,640 feet (500 metres) above sea level at Mendoza to 66 feet (20 metres) at Buenos Aires. Apart from a few sierras in the northwest and south, most of the region appears perfectly flat.

The climate is warm making the soils appropriate for agriculture.

Herbivores of the pampas are the pampas deer, guanaco, gray brocket, dwarf mara, plains viscacha, Brazilian guinea pig, southern mountain cavy and coypu.

The biggest predator of the region is the puma followed by the maned wolf, pampas fox, geoffroy's cat, lesser grison as well as the omnivorous white-eared opossum and molinas hog-nosed skunk.
