Summary A preliminary pollenanalytical study of a peat bog near Canolo Nuovo (900 m a.s.l.) in southern Calabria revealed new information about the late pleistocene vegetation history of this part of the Mediterranean region. Zone A: The study area was occupied by a beech-fir-forest 37000 radiocarbon years BP. and earlier, during a time span corresponding to the Dutch Hengelo interstade, which was a period of shrub tundra in the Netherlands. Zone B represents part of the Older Dryas period. As allover the Mediterranean region there was no forest in southern Calabria during this time. Trees might, however, have existed in a belt below 900 m a.s.l., as there are small quantities of pollen of beech, fir, oak, pine and others registrated throughout all of zone B. Zones A and B are separated from one another by an hiatus. Another hiatus on top of zone B covers the period of reforestation of this area. Thus zone C is of late postglacial age only. There is an excellent agreement between Canolo Nuovo and Ioannina/NW-Greece concerning late pleistocene vegetation and climate, as shown by zone A and its radiocarbon dated equivalent at Ioannina. A correlation of this zone with those of more distant sites, based on 14C-dates only, does not lead to a conclusive view of the vegetation of this part of the last glacial period in the Mediterranean region. On the other hand, a correlation of forest phases with a similar character of vegetation and climate from different sites with one another is possible only, if one rejects complete series of 14C-dates. |
