Argentina

Argentina extends more than three thousand five hundred kilometres from north to south and strings together the subtropical forest of Misiones, with the Iguazú Falls, the dry Chaco, the Iberá wetlands, the pampas, the Patagonian steppe, the Andes with Aconcagua, and the forests and glaciers of the south as far as Tierra del Fuego. The Valdés peninsula, on the Atlantic, is an exceptional enclave where southern right whales come to calve alongside elephant seals, sea lions and Magellanic penguins in colonies of hundreds of thousands of pairs. In the northwest, the puna and the high-altitude salt flats hold flamingos and vicuñas, and on the river lowlands the Iberá marshes have become the largest rewilding project in the Americas.
