Alto Paraná Atlantic forests, Subtropical moist forest ecoregion across Brazil, Paraguay, and Argentina
The Alto Paraná Atlantic forest is a subtropical moist forest spanning Brazil, Paraguay, and Argentina, characterized by semi-deciduous trees that dominate the landscape. These trees drop their leaves during the dry season, creating a shifting environment from season to season.
The forest originally covered multiple Brazilian states including Minas Gerais and São Paulo before agricultural expansion destroyed much of it over the past century. This major loss triggered conservation efforts to protect what remains today.
These forests are home to a remarkable array of wildlife, including numerous bird and mammal species like the black lion tamarin. For the local communities across the region, the forests represent a vital connection to the natural world.
The region receives between 1,200 and 1,600 millimeters of annual rainfall, with a dry season running from April through September. Visitors should plan their visits with this seasonal pattern in mind.
Each hectare contains around 450 different tree species, making this region extraordinarily biodiverse. Additionally, 90 percent of amphibians and 50 percent of plant species are found nowhere else on Earth.
