Ecoregions of Paraguay

The Cerrado is the largest savanna region in South America and the largest ecoregion in the Americas. It encompasses central Brazil as well as small portions of Paraguay and Bolivia. Biologically the richest savanna in the world, it contains extraordinary biodiversity.

The Dry Chaco ecoregion, or Gran Chaco, is a sparsely populated, hot, semi-arid lowland alluvial plain of the Río de la Plata basin. It is divided among eastern Bolivia, western Paraguay, northern Argentina, and a portion of Brazil. The Chaco contains South America's second-largest forest after the Amazon.

The Humid Chaco ecoregion occupies the lowlands of the Paraná River, covering portions of northeastern Argentina, the center of Paraguay, and small areas in southwestern Brazil. The natural vegetation is a mosaic of grasslands, palm savanna, and forest.

The Pantanal is a natural region encompassing the world's largest tropical wetland. This gigantic seasonal floodplain lies mainly within Mato Grosso, and Mato Grosso do Sul in the Center-West Region of Brazil. However, small portions extend into northeastern Paraguay and southeastern Bolivia.

The Upper Paraná Atlantic forests, or "Selva Paranaense," is an ecoregion of the tropical moist forests biome and the South American Atlantic Forest biome. The ecoregion stretches across the borders of southern Brazil, eastern Paraguay, and northeastern Argentina.
