The growth of trees directly reflects the performance of entire forest stands. It depends, among other things, on the soil conditions, the genetic makeup of the stock, climatic conditions, the influence of air pollutants and biotic influences (e.g. fungi, insects). In order to ensure stable forest ecosystems in the long term, questions about the location-dependent choice of tree species, the growth response to environmental conditions and the need for changed use strategies under the conditions of climate change must be clarified. We record the growth of trees, for example with a dendometer. In contrast to classic increment tape measures, modern dendrometers enable automatic, continuous measurement of diameter changes. This allows the effects of extreme climatic events on tree growth to be recorded in a timely manner. This can now also be followed in real time on the intensive monitoring area in Britz.
