Fig. 2. The Omora Park extends 920 m from the Beagle Channel to the summit of Robalo Mountain. This altitudinal gradient includes the characteristic habitat types of the Cape Horn region. From the shoreline upwards these habitats are: evergreen forests dominated by Nothofagus betuloides (Nb); mixed evergreen-deciduous forests dominated by N. betuloides and N. pumilio (Np); deciduous forests dominated by N. pumilio and N. antarctica (Na); alpine tundra dominated at lower levels by cushion plants, e.g., Bolax gummifera (Bg); and at upper levels by lichens (Neuropogon sp. (Nsp). For an illustration of these habitat types see Appendix 1.
