Data on multi-year drought impacts on European beech in northern Switzerland

We conducted the study in two highly drought-affected regions in northern Switzerland and one less drought-affected region located further south. We quantified the development of crown dieback and tree mortality as well as secondary drought damage, i.e. the presence of bleeding cankers and bark beetle infestations, in these trees for three consecutive years.

We also determined the impact of several potential climate- and stand-related (predisposing) factors on mortality and drought legacy processes.
