The Atlantic Forest or Mata Atlântica stretches along Brazil's Atlantic coast, from the northern state of Rio Grande do Norte south to Rio Grande do Sul. It extends inland to eastern Paraguay and the province of Misiones in northeastern Argentina, and narrowly along the coast into Uruguay. Also included in this hotspot is the offshore archipelago of Fernando de Noronha and several other islands off the Brazilian coast. Long isolated from other major rainforest blocks in South America, the Atlantic Forest has an extremely diverse and unique mix of vegetation and forest types. The most extensive woodland/savanna region in South America, the Cerrado is also the only hotspot that consists largely of savanna, woodland/savanna and dry forest ecosystems. Within the region, there is a mosaic of different vegetation types, including tree and scrub savanna, grassland with scattered trees, and occasional patches of a dry, closed canopy forest called the cerradão. Gallery forests are found throughout the region, although they are technically not considered part of the typical Cerrado formations.
Structural definition of ecoregions
Ecoregions are areas that:  share a large majority of their species and ecological dynamics;  share similar environmental conditions; and,  interact ecologically in ways that are critical for their long-term persistence. Scientists at the World Wildlife Fund (WWF), have established a classification system that divides the world in 867 terrestrial ecoregions, 426 freshwater ecoregions and 229 marine ecoregions that reflect the distribution of a broad range of fauna and flora across the Earth.
