The Chaco bioregion, located in the Southern America (Neotropical) realm, covers much of Paraguay and northern Argentina. The name of this region is derived from the indigenous Quechua word chaqu which means “hunting land,” due to the rich variety of wildlife that was once abundant in these subtropical grasslands and shrublands. The bioregion contains two ecoregions – Dry Chaco (569), Humid Chaco (571) – incorporating several large salt flats in the south. The land area of this bioregion is more than 108 million hectares.

The Chaco Grasslands bioregion is part of the South American Grasslands subrealm and is made up of two ecoregions: (1) Dry Chaco (2) Humid Chaco.
