The Rio de la Plata bioregion, located in the Southern America (Neotropical) realm, extends from the Espinal drylands east of the Andes Mountains to the Atlantic Ocean, encompassing Argentina’s humid pampas grasses and the flooded savannas formed by the Paraná River and its tributaries. This bioregion also includes Uruguay’s subtropical savanna, which forms the Northern border of the Río de la Plata estuary, containing five ecoregions in total – Uruguayan Savanna (574), Espinal (575), Humid Pampas (576), Paraná Flooded Savanna (585), Southern Cone Mesopotamian Savanna (586) – as well as adjacent marine areas in the Atlantic Ocean. The total land area of this bioregion is more than 111 million hectares.

The Rio de la Plata Grasslands bioregion is part of the South American Grasslands subrealm and is made up of five ecoregions: (1) Espinal (2) Humid Pampas (3) Paraná Flooded Savanna (4) Southern Cone Mesopotamian Savanna (5) Uruguayan Savanna.
