Humid Chaco

WWF Abstract

The Humid Chaco stretches across the myriad landscapes of southeastern South America, creating a transition zone between the Arid Chaco ecoregion to the west and the humid tropical forests to the east. Parts of this ecoregion are so thick with vegetation that locals have dubbed it El Impenetrable. The region encompasses the northern Paraná River and its Flooded Savannas ecoregion and extends north into central Paraguay. Bogs and other wetlands, grasslands, savannas, and gallery forests come together here in a mosaic of habitats.
