Gran Chaco

Region of south-central Southern America

The Gran Chaco (also called Chaco or Chaco Plain) is a vast semiarid lowland region in central South America, spanning over one million square kilometres (390,000 sq mi) across eastern Bolivia, western Paraguay, northern Argentina, and parts of Brazil. It forms part of the Río de la Plata basin. The Gran Chaco features a mix of tropical and subtropical dry broadleaf forests, thorn scrub, savannas, wetlands, and palm groves, making it the continent's second-largest forested ecoregion and a region of high ecological diversity.
