Atlantic Forest, Tropical rainforest biome along Brazil's Atlantic coast
The Atlantic Forest is a tropical rainforest system that stretches roughly 3000 kilometers along the Brazilian coastline, passing through several climate zones. The region spans from northeastern states down to the southern state of Rio Grande do Sul, covering varying elevations from sea level to mountain ranges.
During the 1500s, the forest covered roughly 1.5 million square kilometers and formed the second largest rainforest system on Earth. Over the following centuries, colonial expansion led to the gradual reduction of this original habitat.
The forests remain sacred grounds for Tupi and Guarani peoples, where ceremonial healing practices and gathering of traditional herbs continue in everyday life. Many coastal communities still follow inherited methods of sustainable forest use, visible during community-led forest walks.
Many protected areas within the region offer trails and visitor centers accessible from cities like Rio de Janeiro and São Paulo. Guided walks with local rangers help with navigation through dense forest sections and provide insight into the wildlife and plant life.
This forest holds around 264 mammal species and roughly 23,000 plant species, with many found nowhere else. Nearly half of its vascular plants grow only here, making this habitat a center of biological diversity.
