The Amazon Rainforest is a natural region and biome in northern South America that occupies the Amazon Basin, a drainage basin of the Amazon River and its tributaries in South America. Nine nations have some part of the Amazon region within their borders.
Natural Regions of South America
The Andean Patagonian Forest spreads over steep elevations along a thin strip on both sides of the Andes Mountains in southern South America. These temperate forests, located in both southern Chile and Argentina, are the southernmost forests on earth.
The Caatinga is the largest dry forest region in South America and also one of the richest dry forests in the world, providing habitat for an array of flora and fauna species. It is home to 26 million people and over 2000 species of plants, fish, reptiles, amphibians, birds and mammals.
Chapada Diamantina National Park is located in the Brazilian state of Bahia. The Chapada Diamantina is a plateau bounded by cliffs which form a watershed, draining on one side into the São Francisco River and on the other into the De Contas River and Paraguaçu River.
The Gran Chaco is a sparsely populated, hot and semi-arid lowland alluvial plain, divided among eastern Bolivia, western Paraguay, northern Argentina and a portion of Brazil. With a high biodiversity, it contains South America's second largest forest.
La Gran Sabana is a region in southeastern Venezuela that offers one of the most unusual landscapes in the world, with rivers, waterfalls and gorges, deep and vast valleys, as well as impenetrable jungles and savannas. The region also hosts the isolated tabletop mesas known as tepuis.
The Altiplano, also called Puna, is a region in west-central South America in the area where the Andes are the widest. It is the most extensive area of high plateau on earth outside Tibet. The bulk of the Altiplano lies in Bolivia but its northern parts lie in Peru and its southern parts lie in Chile and Argentina.
The Cerrado is the largest savanna region in South America and the largest ecoregion in the Americas. It encompasses central Brazil as well as small portions of northeastern Paraguay and eastern Bolivia. Biologically the richest savanna in all the world, it contains an extraordinary amount of biodiversity.
The Pampas are a natural region of vast fertile lowland plains in South America that extend from the Atlantic Ocean to the Andes Mountains. These flat, fertile plains are a grassland biome that can be divided into three distinct ecoregions: the Uruguayan Savanna, the Humid Pampas and the Semiarid Pampas.
Stretching across Brazil, Bolivia and Paraguay, the Pantanal is a natural region encompassing the world's largest tropical wetland area. Although not as well known as the Amazon Rainforest to its north, this gigantic seasonal floodplain is also home to a staggering variety of plants and wildlife.
