"Due to the likelihood of global climate change, the frequency and magnitude of natural  hazards such as mass movements may likewise change, thus favouring the  refinement of methods to detect and quantify geomorphic events when precise  records are not available. Geomorphic events typically have a significant effect on tree  growth, e.g., reaction wood marked by changes in ring widths and wood density. To  date, several dendroecological techniques have been developed to document the  occurrence of these events but it rarely has been possible to retrieve additional  information from reaction wood concerning the precise kind and intensity of  geomorphic events. Additional qualitative information inferred from reaction wood of  trees holds the potential to not only document but also estimate important  characteristics of natural hazard events. To refine the methods already used in  dendrogeomorpology, experiments simulating various geomorphic events were used  to monitor subsequent wood anatomical responses of Fagus sylvatica and Alnus  glutinosa. The preliminary results indicate that these two common broadleaf tree  species show variations in their reactions to different experimental treatments."
