Purpose of research: Applied research
In the face of climate warming forestry in Germany needs decision support for forest conversion, which is necessary at many sites. So far, in forest conversion climatic suitability of a species take the center of considerations. Consequently, a change of tree species raise the question, whether the nutrient supply at a site is also sufficient for alternative climate-adopted tree species. However, there are significant knowledge gaps about the interaction between climate and nutrition, in particular at the environmental limits of tree species. The aim of this study is to specify biogeochemical thresholds for the cultivation of the most important forest tree species in Germany on the basis of monitoring data and to deduce the tree species suitability on this basis. The resulting thresholds, which characterize specific site ranges (range of species exclusion; range of strong and weak nutrient limitation, as well as no limitation) should assist forestry planting decisions and should be integrated in forestry handbooks on site classfication.
