The workshop will be a forum for presenting and discussing results of research on a network of 11 Oriental beech stands across France, Germany, and Switzerland. Talks given by researchers will cover comparative analysis of European and Oriental beech regarding their phenology, growth and wood anatomy, physiology, and genetics. In particular, extensive research will be presented on the hybridization of the two species and its consequences on the long-term survival of the stands. We will also discuss if remote sensing can be used to track the spread of Oriental beech in a European beech forest. Talks given by foresters and responsible administrative bodies will cover the point of view of forestry practice and the potential for the development of a protected network of sites.
All talks on Tuesday, 10 June, will be given in English and simultaneously translated
