Pampas
South American fertile, treeless lowland
The Pampas (; from Quechua pampa 'plain'), also known as the Pampas Plains, are fertile low grasslands in southern South America that cover more than 1,200,000 km2 (460,000 sq mi) and include the Argentine provinces of Buenos Aires, La Pampa, Santa Fe, Entre Ríos, and Córdoba; all of Uruguay; and Brazil's southernmost state, Rio Grande do Sul. The vast plains are a natural region, interrupted only by the low Ventana and Tandil hills, near Bahía Blanca and Tandil (Argentina), with a height of 1,300 m (4,265 ft) and 500 m (1,640 ft), respectively. This ecoregion has been changed by humans, especially since the release of animals like cattle, pigs, and especially sheep onto these plains.
The climate is temperate, with precipitation of 600 to 1,200 mm (23.6 to 47.2 in) that is more or less evenly distributed throughout the year, making the soils appropriate for agriculture. The area is also one of the distinct physiography provinces of the larger Paraná–Paraguay plain division.
It is considered that the limit of the Pampas plain is to the north with the Atlantic Forest and the Great Chaco Plain, to the west with the Pampas Mountains and the Cuyo Region, and to the south with Patagonia.
Topography
This region has generally low elevations, whose highest levels generally do not exceed 600 metres (2,000 ft) in altitude. The coastal areas and most of the Buenos Aires Province are predominantly plain (with some wetlands) and the interior areas (mainly in the southern part of the Brazilian state of Rio Grande do Sul and Uruguay) have low ranges of hills (like Serras de Sudeste in Brazil and Cuchilla Grande in Uruguay). Low hills covered by grasslands are called coxilhas (Portuguese pronunciation: [koˈʃiʎɐs]) in Portuguese and cuchillas (Spanish pronunciation: [kuˈtʃiʝas]) in Spanish, and it is the most typical landscape of the countryside areas in the northern parts of the Pampas. The highest elevations of the Pampas region are found in the Sierra de la Ventana mountains, in the southern part of Buenos Aires Province, with 1,239 metres (4,065 ft) at the summit of Cerro Tres Picos.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Pampas”, the useful work is to connect “south American fertile, treeless lowland” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 16, 2026. The linked authority identifier is Q184382. VIAF identifies the subject as 315127587. The Library of Congress control number is sh85097286. Authority coordinates are -35.000, -62.000. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
