Fig. 1. Location of the Omora Park on Navarino Island south of Tierra del Fuego and the Beagle Channel, in the region of Cape Horn, at the southern extreme of the American Continent. Dark green depicts the subantarctic or subpolar Magallanic evergreen rainforest ecoregion, which runs along the Chilean Pacific Coast from Golfo de Penas (48 S) to Cape Horn (56 S). This ecoregion has been identified as one of the 37 most pristine areas in the world. The criteria to identify the most pristine ecoregions or wilderness areas in the world were: (1) 70% or more of their original vegetation intact, (2) cover at least 10,000 km2, and (3) have fewer than five people/km2 (Mittermeier et al. 2002).
