Ecoregions of Brazil

Brazil is South America's largest country, occupying half of its landmass. It is the fifth largest country in the world and is regarded as the most biodiverse country on Earth. The country is conventionally divided into five geographic regions corresponding to its significant landforms and biomes.

The Caatinga is a vast and unique semiarid biome that covers northeast Brazil and is home to various ecosystems, making it the largest dry forest region in South America. This region is characterized by its arid, thorny, and seasonal vegetation, which provides habitats for more than 2,000 species. Recognized as a biodiversity hotspot, the Caatinga faces significant threats, primarily due to land conversion for agriculture and cattle ranching.

The Cerrado, South America's largest savanna region and the most extensive ecoregion in the Americas unfolds across central Brazil, extending its natural wonders into northeastern Paraguay and eastern Bolivia. This savanna, boasting unparalleled biological richness, is a global treasure, home to 5% of the planet's animals and plants and harboring an extraordinary menagerie of life.

The Gran Chaco, or simply Chaco, is a vast and intriguing expanse that stretches across eastern Bolivia, western Paraguay, northern Argentina, and parts of the Brazilian states of Mato Grosso and Mato Grosso do Sul, seamlessly connected with the Pantanal region. Located in the rain shadow of the Central Andes, it is primarily an alluvial sedimentary plain, home to South America's second-largest forest after the Amazon rainforest. However, it is also one of the most deforested areas in the world.

The Pantanal, the world's largest tropical wetland, unfolds as a colossal seasonal floodplain predominantly situated within Mato Grosso and Mato Grosso do Sul in Brazil's Center-West Region. However, its expansive reach extends into northeastern Paraguay and southeastern Bolivia, creating an ecological masterpiece that captivates with its diverse landscapes and vibrant ecosystems. This remarkable wetland supports a rich array of wildlife and plant species, making it one of the most biodiverse areas on the planet.
