Esteros del Ibera, Argentina
The Iberá Wetlands 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 20,000 km squared. It is planned to protect the wetlands by making it a national park.
