Ecoregions of Paraguay

Discovering the Upper Paraná Atlantic Forests: A Treasure of Biodiversity

The Upper Paraná Atlantic forests, also known as "Selva Paranaense," represent a verdant expanse of tropical moist forests nestled within the South American Atlantic Forest biome. This ecoregion, characterized by its rich biodiversity and ecological significance, stretches across the southern reaches of the Brazilian Highlands, extending through southern Brazil, eastern Paraguay, and northeastern Argentina.

The Dry Chaco: A Realm of Resilience, Where Life Thrives Against the Odds

The Dry Chaco ecoregion, the arid part of the Gran Chaco, spans western Paraguay, northern Argentina, southeastern Bolivia, and a small area of Brazil. This lowland, mainly in the rain shadow of the Central Andes, features a landscape shaped by limited rainfall, intense solar radiation, and extreme seasonal temperatures. Rather than a barren wasteland, the Dry Chaco showcases a unique biodiversity of plants and animals that have evolved remarkable adaptations to thrive in this challenging environment.

The Humid Chaco: A Realm of Green and Water, Where Life Flourishes in Abundance

The Humid Chaco ecoregion, the eastern counterpart to the drier expanses of the Gran Chaco, stretches across eastern Paraguay, northeastern Argentina, and a small portion of southeastern Brazil. In contrast to the aridity that defines its western neighbor, the Humid Chaco is characterized by higher rainfall, more fertile soils in certain areas, and a greater abundance of surface water. This results in a landscape teeming with diverse forests, expansive savannas that experience seasonal flooding, and intricate riparian ecosystems.

The Paraná Flooded Savanna: Guardian of the Flooded Realm

The Paraná Flooded Savanna ecoregion is a vast area that spans across the floodplains of the middle and lower Paraná River, along with its tributary, the Paraguay River. This region is home to diverse flora and fauna, crucial for maintaining the ecological balance in Argentina and Paraguay. This region's intricate network of waterways and lush marshlands provides a secure habitat for countless plant and animal species.
