Site description Located within the South African mistbelt, between Graskop and Sabie, this site consists of a patchwork of forestry plantations that still hold superb patches of fragmented indigenous forest, as well as some remaining grassland and sheer cliffs. The site consists of Mariti, Waterhoutboom, Mac-Mac, Frankfort, Bergvliet, Klipkraal, Rietfontein, Waterfal and Ceylon plantations. Approximately 60% of the area is under pine Pinus plantation, while the remaining 40% holds escarpment cliffs with associated grassland and indigenous forest.Fragmented patches of indigenous habitat may be found in and around the plantation matrix. The thornveld of mountain slopes holds scrubby Phymaspermum, Buddleja and Leucosidea along the streams. Patches of fynbos holding Erica and Protea bushes also occur. The forests, which are restricted to the more mesic valleys, are dominated by trees of Rapanea, Podocarpus, Trichocladus and Curtisia. Dense stands of non-native trees, including wattle Acacia and Eucalyptus, have invaded and replaced much of the remaining indigenous vegetation, and continue to spread uncontrolled, encroaching on the remaining grassland.
