The Mata Atlântica Biosphere Reserve protects one of the most biodiverse and threatened tropical forests in the world, spanning Brazil’s Atlantic coast and offering remarkable opportunities for wildlife viewing, hiking, and nature exploration.
The Mata Atlântica Biosphere Reserve comprises a vast and ecologically significant remnant of the Atlantic Forest, which once stretched along Brazil's Atlantic coastline and parts of eastern Paraguay and northeastern Argentina. Characterized by dense tropical and subtropical broadleaf forests, this reserve spans multiple Brazilian states, including Paraná, Santa Catarina, Rio de Janeiro, and São Paulo, among others. It features a rich mosaic of ecosystems such as rainforests, mangroves, restingas, and high-altitude cloud forests. The biodiversity here is extraordinary, with high levels of endemism; the forest is home to thousands of plant species and animals, including endangered species like the golden lion tamarin, jaguar, and various amphibians unique to the region.
Historically, the Mata Atlântica has faced severe deforestation and habitat fragmentation due to urbanization, agriculture, and industrial developments, making conservation efforts critical. The designation as a UNESCO Biosphere Reserve emphasizes sustainable use and preservation, balancing human activity with ecological integrity. Visitors to the Mata Atlântica Reserve can experience a range of outdoor activities such as hiking through lush trails, birdwatching rare species, and exploring waterfalls and rugged terrain.
Notable landmarks within the biosphere include areas protected by various national parks and biological reserves, such as Serra do Mar State Park and Tijuca National Park—the world's largest urban forest located in Rio de Janeiro. The reserve also offers a unique cultural landscape, interspersed with small communities that maintain traditional land uses. As a destination, it appeals to nature enthusiasts, researchers, and travelers seeking immersive encounters with one of Earth’s most vital and challenged forest ecosystems.
