Drought risk and adaptive potential of different Norway spruce populations
Climate change affects forest ecosystems in particular by more frequent and intensive extreme weather events. Heat waves and drought events play an important role. Among the major tree species in Germany Norway spruce seems to be the most sensitive one. Decision makers in forestry expect an increasing management risk of Norway spruce which is the most important economic tree species in Germany.
Within the project we will study different populations and provenances throughout the distribution range of Norway spruce in Europe distinguishing between central provenances and rear-edge provenances originating from xeric environments. Drought tolerance will be assessed using growth and vitality indicators, and the results will be linked to physiological biomarker and genetic markers. This will provide a novel tool to evaluate the drought tolerance of different spruce provenances. Options and limitations of the regional adaptive capacity of different spruce provenances shall be assessed that can be implemented in future objective risk analyses for existing spruce stands.
