Atlantic Forests

The Basin

The Atlantic Forests is a terrestrial region, which extends over 4,000 km2 (1,500 sq mi) along the Atlantic coast of Brazil and inland as far as Paraguay and Argentina. Two of the world’s largest cities – Rio de Janeiro and São Paulo, lie within the Atlantic Forests ecoregion. Long isolated from the Amazon Basin by the drier Cerrado region to its west, the Atlantic Forests ecoregion fostered the evolution of many distinctive plant and animal communities. 8000 tree and shrub species are endemic to the Atlantic Forests and 1,020 bird species call it home, while 92 percent of the forests amphibians are found nowhere else on Earth.
