The Brazilian Chaco: A Unique Biogeographic Frontier

Located in the municipality of Porto Murtinho, the Brazilian Chaco is a crucial part of the vast Gran Chaco biome, which spans Argentina, Bolivia, and Paraguay. This approximately 9,000 km² area in Mato Grosso do Sul is a transitional zone, influenced by the adjacent Southern Pantanal and Cerrado, yet maintaining its own distinct ecological identity.

The habitat is characterized by xeric vegetation, featuring dense forests of thorny trees like the resilient red quebracho (Schinopsis balansae). These dry forests and scrublands create a unique environment that supports an impressive diversity of birds, including many Chaco endemics and specialties.
