Esteros del Iberá
Se denomina Esteros del Iberá a un extenso humedal que abarca entre 15.000 y 25.000 km² en la provincia de Corrientes, en el noreste de República Argentina. Solo superado en extensión por el Pantanal (brasileño, boliviano y paraguayo) con el cual forman el segundo humedal más grande del mundo, parte de un sistema hidrográfico mucho más extenso el macrosistema del Iberá, de cerca de 1.300.000 ha— en el que se desarrolla un ecosistema subtropical y tropical de grandísima diversidad.
The Iberá Wetlands (Spanish: Esteros del Iberá, from Guaraní ý berá: bright water) are a mix of swamps, bogs, stagnant lakes, lagoons, natural slough and courses of water in the center and center-north of the province of Corrientes, Argentina.
Iberá is one of the most important fresh water reservoirs in the continent and the second-largest wetland in the world after Pantanal in Brazil. It is of pluvial origin, with a total area of 15,000–20,000 km2 (5,800–7,700 sq mi).
Since 1982, part of the wetland is included within a provincial protected area, the Iberá Provincial Reserve, which comprises about 13,000 km2 (5,000 sq mi), the largest of such areas in Argentina. There are ongoing plans to further up its protection status to national park.
