Figure 2 World image showing that southern South America extends 9 degrees (°) beyond the latitude of Stewart Island, New Zealand (47° south [S], indicated by the dashed red line). Therefore, the world’s southernmost forests in the sub-Antarctic Magellanic ecoregion have no replica in the Southern Hemisphere. In contrast to the vast cross-continental span of boreal forests in the Northern Hemisphere, the austral temperate forest biome narrows down to an identifiable point: Cape Horn Island (56° S). The white dashed lines enclose the latitudinal bands at 40°-60° in both hemispheres to illustrate the marked difference in land:ocean ratios at this latitudinal range (indicated in bold in the table). (2) One of the last wilderness areas. Among the 12 largest remnants of old-growth forest in the planet, the South American temperate forest biome is the only one that is nei- ther tropical nor boreal (Armesto et al. 2009). According to Bryant and colleagues (1997), 90% of the world’s remaining frontier forests are found in only 12 countries, most of them in the tropical regions and in the Northern Hemisphere. The boreal and temperate forests of Russia, Canada, and the United States account for more than 59% of the remnant frontier forests (figure 3). Tropical forests in eight coun- tries in turn (Brazil, Peru, Indonesia, Venezuela, Colombia, Zaire, Bolivia, Papua New Guinea) add up to almost 40% of the frontier forests. Only one nontropical country in the Southern Hemisphere (Chile) is included in the list, and it contributes only about 1% of the world’s frontier forests. In addition, the sub-Antarctic Magellanic forest ecoregion has been identified as one of the 24 wilderness areas remain- ing on the planet (sensu Mittermeier et al. 2003) for the following three reasons: (1) more than 70% of its original vegetation cover is conserved, (2) it encompasses an area of more than 10,000 km? that lacks terrestrial connectivity and industrial and urban development, and (3) it harbors one of the lowest human population densities within temperate latitudes (0.14 inhabitants per km?). (1) The absence of latitudinal equivalents in the Southern Hemisphere. Temperate forests occur along the southwestern margin of South America, ending in the sub-Antarctic Magellanic ecoregion. The latter spans a myriad of archipela- goes from 47° S to 56° S over a latitudinal range that stretches almost 10° of latitude beyond the southernmost forests in New Zealand and Australia, on Stewart Island (47° S) and
