It is very well known that you can count the rings to figure out the age of a tree. Tree-ring research or Dendrochronology, however, goes beyond that because trees record environmental changes and impacts in each annual ring. Trees are thus a great archive for the past with high temporal resolution. Tree-ring analysis can be applied to various climatological and ecological research questions, including inter alia, climate reconstructions, growth responses to extreme climatic events, insect outbreaks or even forest damage through warfare. This talk will give a short introduction to Dendrochronology in general, and some examples will demonstrate the steadily expanding application areas of this discipline. Dr Claudia Hartl is a dendrochronologist, geographer and ecologist with a strong background in climatology. Her research is generally focused on tree-rings but the spectrum of topics is broad, as trees with their long lifespan and annual resolution can tell a variety of different stories. Dr Hartl is based at Johannes Gutenberg University Mainz and uses different tree-ring parameters, such as tree-ring width, stable isotopes and maximum latewood density, for studying various forest ecosystems mostly across Europe.
