The growth of trees directly reflects the performance of entire forest stands. Among other things, it depends on soil conditions, the genetic make-up of the stand, climatic conditions, the influence of air pollutants and biotic influences (e.g. fungi, insects). In order to ensure resilient forest ecosystems in the long term, questions regarding the site-dependent selection of tree species, the growth response to environmental conditions, and the effects of different utilization strategies under climate change must be answered.
