This watery Eden in northern Argentina is a natural paradise of flora and fauna, covering an area of approximately 15,000 km². It is one of the most important freshwater reservoirs on the continent and the second-largest wetland in the world (after the Pantanal in Brazil). Located 800 km north of Buenos Aires, the wetlands are of pluvial origin, formed by abundant rainfall over thousands of years. Bird-watchers flock to its watery canals to seek out the 350-plus avaian species that can be found there. The Ibera Wetlands are also home to capybaras, howler monkeys, caiman, deer, otters, and anacondas.
