UNESCO Description of the World Heritage Site

The Atlantic Forest South-East Reserves, in the states of Paraná and São Paulo, contain some of the best and most extensive examples of Atlantic forest in Brazil. The 25 protected areas that make up the site (some 470,000 ha in total) display the biological wealth and evolutionary history of the last remaining Atlantic forests. From mountains covered by dense forests, down to wetlands, coastal islands with isolated mountains and dunes, the area comprises a rich natural environment of great scenic beauty.

UNESCO Justification of the World Heritage Site

The Atlantic Forests (Southeast) contain the best and largest remaining examples of Atlantic forest in the southeast region of Brazil. The 25 protected areas that make up the site display the biological richness and evolutionary history of the few remaining areas of Atlantic forest of southeast Brazil. The area is also exceptionally diverse with high numbers of rare and endemic species. With its “mountains to the sea” attitudinal gradient, its estuary, wild rivers, karst and numerous waterfalls, the site also has exceptional scenic values.
