Iberá Provincial Reserve, Nature reserve in Corrientes Province, Argentina

Iberá Provincial Reserve covers about 1,300,000 ha, roughly 14% of Corrientes Province, and is Argentina's largest protected area. Its shallow lagoon system includes the Iberá and Luna lagoons, on whose banks Colonia Carlos Pellegrini was founded, plus Fernández, Galarza, Medina, Paraná and Trin, each over 15 km2. Floating vegetation forms natural dams sometimes firm enough to walk on, and the solid ground shifts constantly.

The reserve was established on 15 April 1983, covering about 1,300,000 hectares, 14% of Corrientes Province. Iberá Provincial Park was created in 2009 from provincial public lands, and Iberá National Park followed on 5 December 2018, built from cattle ranches that Doug and Kristine Tompkins's Conservation Land Trust had bought since 1999 and donated to the state in 2015.

The wetlands have shaped how people in the region live and work with nature over generations. Local residents view the landscape as central to their identity and economic opportunities.

You can enter the reserve through four main gates, each offering different viewpoints and ways to explore the area. Choose your entry point based on what you want to see and how much time you have available.

The red-and-green macaw reintroduction began with captive birds imported from Britain in 2015; the first pair was released in February 2019. The species is listed as critically endangered in Argentina and had been considered extirpated there since the 1960s. The reserve also protects four species declared provincial natural monuments, among them the neotropical otter and the maned wolf.
