The Guanaco is the wild South American ungulate with the broadest geographical distribution. The Guanaco is found in northwestern Peru (8°S), in the western and southern Bolivia, northwestern Paraguay, and throughout the Andes of Chile and Argentina eastward to the Atlantic coast and southward to the islands of Tierra del Fuego and Navarino (55 °S). The guanaco occupies a wide range of arid and semiarid ecosystems from sea level to over 4,500 meters in elevation. It is estimated that over 90% of guanacos in Argentina are found in the Patagonia.
