Abstract

Abstract: Here we present charcoal identifications for Rose Cottage Cave, Eastern Free State, from layers dated between about 96, 000 and 35, 000 years ago (~96 and ~35 ka ago). We then suggest plant community types that might have been established in the area in warm Marine Isotope Stage 5 (MIS5) versus cooler MIS4/MIS3 phases. The hypothesis is that frost-tender plants should occur in warm phases while hardy Leucosidea sericea, Protea spp. and Erica spp. should be more common during cooler phases more recent than ~74 ka ago. Leucosidea sericea thrives under moist conditions and its presence in late MIS4 and in several MIS3 layers at Rose Cottage implies that the area may have been moister than many other sites in the interior of southern Africa, thereby making it attractive for occupation. The charcoal identifications at ~96 ka ago included taxa like Buddleja salvifolia that need somewhat warmer conditions than taxa such as Leucosidea sericea . Taxa diversity based on the charcoal identifications is generally low at the site throughout the Middle Stone Age, but the vegetation from relatively warm MIS5 seems more diverse than that of MIS4 and MIS3. Some taxa identified, for example, Calodendrum capense, Leucosidea sericea, Erica caffra and Protea caffra no longer grow near the cave although they are commonly found in other parts of eastern South Africa.
