Beschreibung:
<jats:p>An improved understanding of the spatiotemporal climate/growth relationship of our forests is of particular importance for assessing the consequences of climate warming. A total of 67 stands of beech (<jats:italic>Fagus sylvatica</jats:italic> L.), pedunculate oak (<jats:italic>Quercus robur</jats:italic> L.), sessile oak (<jats:italic>Quercus petraea</jats:italic> (Matt.) Liebl.), Scots pine (<jats:italic>Pinus sylvestris</jats:italic> L.), and spruce (<jats:italic>Picea abies</jats:italic> Karst.) from sites located in the transition zone from the lowlands to the low mountain ranges of West Germany have been analysed. A combination of pointer year and cluster analysis was used to find groups with similar growth anomaly patterns over the 1941–2000 period. Shifted reaction patterns especially characterise differences in the growth behaviour of the clusters. These are controlled by different reactions to the climate conditions in winter and spring and are determined by a complex system of forcing factors. Results of this study reflect the enormous importance of the length of the growing season. Increasing the duration of the vegetation period climate warming can change the climate/growth relationship of trees, thereby confounding climate reconstructions which use tree rings. Since forcing factors have been detected that are more important than the tree species, we recommend the application of growth-specific approaches for the analysis of tree species’ vulnerability to climate.</jats:p>
