• Using tree rings as an archive for environmental conditions of Norway Spruce
  Description of the project:

  Environmental influences as for example changes in climate and weather in competition, and also in abiotic and biotic influences have an effect on the anatomic structure, as well as on the physical and chemical properties of tree rings. Tree rings can be dated back over many centuries. Therefore, they offer a valuable insight into former environmental conditions. The aim of this research at the Institute for Forest Growth is to identify the information stored in these tree rings and to make this information available for environmental research. For this purpose, methods for the preparation of large surfaces of cross sections, computer-supported measurements of cell structure with optical and mechanical tools as well as physical and chemical properties in high spatial resolution are used and their diagnostic value for dendroecological research topics is checked.
