The subproject works on two key aspects: Physiological, structural, biochemical and growth responses of important tree species to weather types will be analyzed for a network of five low-elevation and five high-elevation sites distributed over the area of the free state of Bavaria. These indicators of climate response will be integrated in a new model that estimates the vitality and stress level of the studied trees. Due to the disperse spatial distribution in different elevation zones, a dendroecological indicator network for Bavaria shall be established that allows a better explanation of regional growth patterns and the estimation of risk potentials during extreme weather conditions for individual forest areas under defined weather types.
The second focus is the establishment of an internet-based network of ten "talking trees"; located in places of public interest close to the forest research sites. These trees are equipped with physiological instruments to monitor the reaction of the trees to climatological factors in real-time. Students from partner schools translate the response of “their” talking tree to the current weather situation in common language and thus contribute to the environmental education of the public.
