Ecoregions of Argentina

Located in the mountainous regions of Southern Atlantic Brazil and extending into northeastern Argentina, the Araucaria moist forests ecoregion is a remarkable example of the ecological abundance found within the Atlantic Forest biome. This coniferous forest ecoregion boasts diverse landscapes, unique flora, and a rich biodiversity.

The Argentine Espinal Ecoregion is a unique and diverse ecosystem in central Argentina. It is characterized by its dry, thorny, and deciduous shrubland forests. The ecoregion stretches across a vast area, forming a natural transition between the wetland ecosystems along the Paraná River to the east and the mountainous Sierras de Córdoba to the west. Although much of the original landscape has been altered due to extensive cattle ranching and agriculture, remnants of the native flora and fauna persist, making the region ecologically significant.

The Central Andean Dry Puna, an arid haven in the high southern Andes of Bolivia, Chile, and Argentina, captivates with arid landscapes, salt flats, and ancient sea remnants. Unique vegetation adapted to extreme conditions and diverse fauna, from Andean camelids to elusive predators and unique birds, thrive in this high-elevation ecoregion. As a mosaic of arid splendor, the Central Andean Dry Puna unfolds a captivating story of adaptation and conservation.

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.

Nestled high amidst the jagged, snow-covered peaks of the Southern Andes lies the Central Andean Puna - a land of rugged resilience crafted from pristine pampas and awe-inspiring altiplano plains. This high-altitude montane grassland stretches across the southern regions of Peru, traversing the rugged Bolivian Altiplano and dipping into the northern corners of Argentina.

Nestled within the heart of Argentina, the Monte Desert and its encompassing ecoregion, the Argentine Monte, offer a captivating glimpse into a realm of stark beauty and remarkable resilience. This vast expanse is a tapestry woven with diverse landscapes, unique flora, and enigmatic fauna. Characterized by its arid conditions and the interplay of mountain ranges, this region is a testament to nature's ability to thrive in even the harshest environments.

Among the rugged contours of the eastern slopes of the Andes in Argentina lies an area of exceptional beauty and ecological significance - the High Monte ecoregion. This expansive montane landscape stretches from the northern reaches near Salta to the southern expanse of Mendoza, blending dramatic topography and diverse ecosystems. Despite the arid embrace of the Andean foothills, life flourishes in unexpected abundance here, defying the harsh environment.

The humid pampas ecoregion, situated in the eastern plains of Argentina, predominantly occupies the province of Buenos Aires. This area, known for its high human population density, is characterized by expansive grasslands and xeric woodlands. As part of the larger Pampas lowland plains region, the humid pampas feature horizontal plains with gentle undulations and occasional low peaks that emerge like islands across the landscape.

At the southernmost reaches of South America, where the mighty Andes curve eastward and the glacial waters of the Southern Ocean collide with the rugged coastline, lies the Magellanic subpolar forests – a realm of untamed wilderness and extraordinary beauty. This terrestrial ecoregion, spanning parts of southern Chile and Argentina, is a testament to nature's resilience and the incredible diversity of life that thrives in even the harshest environments.

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.
