To protect nature, animals, and live in harmony

Onçafari was created to preserve Brazilian biodiversity through the protection of natural areas and by supporting the socioeconomic development of local communities.

We work for the preservation of biodiversity in 4 Brazilian biomes: Amazon, Cerrado, Pantanal, and Atlantic Forest.
