Argentina: Iberà Wetlands and the Gran Chaco

The Iberà Wetlands (Esteros del Iberà, from Guarani 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.

The Gran Chaco is an area in the north of Argentina, which is dry forest in the west and savannah in the east. The precipitation decreases from east to west and is concentrated on the summer half-year, in winter there are frequent droughts.
