Beiträge von Forstpflanzenzüchtung und Forstgenetik für den Wald von morgen : 7. Tagung der Sektion Forstgenetik/Forstpflanzen-züchtung vom 12. bis 14. September 2022 in Ahrensburg : Tagungsband

The 7th meeting of the “Section Forest Genetics/Forest Tree Breeding” and the German Dendrology Society (DDG) took place in Ahrensburg/Schleswig-Holstein from September 12–14, 2022. The focus of the three-day lecture event was on "Contributions of Forest Plant Breeding and Forest Genetics to the Forest of Tomorrow". There was more than enough reason for the conference. Climate change is becoming more and more obvious. The effects of the excessively dry and warm years in large parts of Germany pose challenges for forest owners and managers. With the meeting we tried to answer some of the questions. At the conference, 51 presentations were given, which were assigned to 10 blocks: Methods, Resistance, Woody Plant Physiology I and II, uropean Beech, Breeding, Differentiation, Alternative Tree Species, Red Oak and Forest Reproductive Material. The conference ended with a half-day excursion to a 60-year-old stand of Monarch birch (Betula maximowicziana), a former provenance trial. At the object a lesser-known tree species of East Asia, knowledge and practical experience were exchanged. Another excursion point was a progeny test for use in short rotation set up by the Thünen Institute of Forest Genetics in strips. For the existing silvoarable agroforestry system (trees with arable crops), a concept for a silvopastoral system (trees with livestock) with chickens or calves was developed together with the Thünen Institute of Organic Farming. In preparation for grazing, half of the elevenyear- old woody strips were harvested during winter and used for energy production. The remaining growth as well as that from root shoots and sockers provide shade and shelter for the brother cocks. The meeting is held as part of the Charta für Holz 2.0, which aims among other things to increase the usable forest wood potential. The conference builds on the following priorities in the field of action Resource Forest and Wood of the Charta: • Sustainable wood supply: productivity and management, Cultivation of productive tree species, guarantee the supply of softwood, Forest tree breeding / forest genetics • Conservation through sustainable use: risk minimization (forest conservation, rotation length, forest conversion), adaptation of forests to climate change, crisis management In order to make the results of the event, which was well attended by 85 participants from Germany and Austria, accessible to a broad public, the content of selected presentations is published.
