Iberá Wetlands
Corrientes
The Iberá Wetlands, locally known as Esteros del Iberá, form a vast complex of swamps, lakes, bogs, and lagoons covering approximately 15,000 to 20,000 square kilometers in the Corrientes province of Argentina. As the second-largest wetland globally after Brazil's Pantanal, Iberá is a crucial freshwater reservoir and hosts a diverse ecosystem including capybaras, caimans, anteaters, otters, and over 350 bird species. The area is characterized by its subtropical and tropical ecosystem, featuring unique flora such as floating islands of aquatic plants called embalsados. Historically threatened by poaching and habitat destruction, conservation and rewilding efforts have successfully reintroduced species like the jaguar, helping to shift the local economy toward sustainable tourism. The wetlands' complex hydrology and difficult access have preserved a rich animal population, including endangered species like the marsh deer and maned wolf. The Iberá Wetlands are protected under the Iberá Provincial Reserve, the largest protected area in Argentina, highlighting their environmental significance and ongoing efforts to upgrade their protection status to a national park.

History
The Iberá Wetlands have formed over millennia as a pluvial system with alluvial soils overlaying impermeable clay, creating slow drainage and extensive water bodies.
The region's geological history involves the shifting course of the Paraná River and erosion processes that shaped the wetland's current morphology.
In 1983, the Argentine government established the Iberá Provincial Reserve to protect approximately 12,000 square kilometers of this unique ecosystem, marking a significant milestone in conservation.
Over time, human activities such as cattle ranching and poaching threatened native species, but recent decades have seen successful rewilding and habitat restoration initiatives.
