Abstract:
Forest growth models are versatile instruments for analysing the influence of environmental changes on plant growth. The aim of this study was to analyse possible adaptation strategies by model simulations combining different growth models. By using the process oriented growth model BALANCE we estimated the influence of climate change on tree growth. The reaction patterns of different and region specific forest stands were then implemented as algorithms in the management-oriented growth model SILVA. The growth of forest stands was simulated with SILVA over 30 years focussing on management options to test different adaption strategies. This approach of combining models with different paradigms is demonstrated for the forest enterprise Zittau. The results of the simulations for the Zittau enterprise convey how forest planning can profit by long term information from scenario analysis. Climate change simulations show that forest stands can lose capacity - e.g. increase capacity - to react on management measures. That means a loss of regulation alternatives for forest planning under the used climate change scenario. A hardwood percentage of 27% in the Zittau forest, on the other hand, possibly has a certain buffer function and moderates the climate change effects on production.
