Prehistoric farming and the postglacial expansion of beech and hombeam: a comment on Küster
Godwin Institute for Quaternary Research, University of Cambridge, Free School Lane, Cambridge, CB2 3SA Küster (1997) has argued that human activity rather than climatic ‘deterioration’ has been responsible for the postglacial expansion of beech (Fagus sylvatica) and hornbeam (Carpinus hetulus) into the oak (Quercus sp.) woodlands of central Europe. We concur that climatic change plays a subordinate role to human activity in the establishment of these taxa, although we feel that the approach adopted by Küster overlooks important ecological and methodological issues. Furthermore, we argue that the expansion of beech is an entirely natural phenomenon which would have occurred without anthropogenic interference but which coincides with early agricultural activity as a result of slow migration and establishment rates. Here we present data from four new palaeoecological sequences collected from sites in Slovenia and Hungary that reveal fluctuations in established forest during the postglacial. In the Slovenian example, anthropogenic activity is seen to reduce beech forest while hornbeam and oak expand to fill the gaps. In the Hungarian examples the response is more complex and includes fluctuations in hazel (Corylus avellana) in addition to hornbeam and oak.
