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.
The Chihuahuan Desert stretches all the way from the southwestern United States deep into the Central Mexican Highlands. This sheltered desert ecoregion is unique, encompassing one of the most biologically diverse arid regions on Earth.
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 Selva, or Peruvian Amazonia, is the area between the eastern foothills of the Peruvian Andes and the rain forests of the Amazon Basin. It is here that the lower slopes of the western Andes merge with the heavily forested tropical lowlands.
Los Llanos is a vast tropical grassland plain situated to the east of the Andes in Colombia and Venezuela, in northwestern South America. It is an ecoregion of the flooded grasslands and savannas biome.
The Mesoamerican Barrier Reef System is a marine region, underwater ecosystem and geological structure that stretches from the Yucatán Peninsula down to Belize, Guatemala and Honduras. This underwater wilderness of coral provide homes and food to hundreds of species.
The Patagonian Desert, also known as the Patagonian Steppe, is a semiarid scrub plateau. The Patagonian steppe ecoregion, also known as the Magellanic Steppe, mainly covers the Patagonia region of Argentina to barely across the border into Chile.
