Summary

The Iberá Wetlands are a large wetland landscape in northeastern Argentina. Lagoons, marshes and floating vegetation support varied wildlife within a region strongly shaped by water.

They offer a distinctive view of Argentina beyond mountains and cities. Close encounters with wetland life reveal the ecological richness of a landscape whose broad surface can initially seem quiet and uniform.

For the curious reader

History, landscape and context.

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 centre and centre-north of the province of Corrientes, Argentina. Iberá is one of the most important freshwater reservoirs in South America 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.
