Geomorphologie und Jahrringe – Feldmethoden in der Dendrogeomorphologie | Geomorphology and tree rings – field methods in dendrogeomorphology

Abstract

In terms of the spatiotemporal reconstruction of geomorphic processes the application of tree-ring analysis has the highest level of temporal resolution in geomorphology. Dating and the resulting reconstructions can be assigned to exact calendar years, sometimes even to specific seasons. To guarantee this,one has to take into account that there are great differences between methods in the field and other tree-ring related fields of research. Following site selection a detailed relief analysis and process must be carried out in order to determine and select those trees obviously disturbed by these processes. The method of sampling is of the utmost importance. Selection of the samples must be based on the estimated kind of disturbance and therefore corresponds to the specific disturbance of a given species and not to the site being investigated. Furthermore,in order to be able to accurately date the disturbances it is absolutely essential to produce a local reference chronology.
