The time of intensive field work came to an end in November 2019. Only one climate stations and the dendrometers remained in the field. Within the last 2,5 years a huge amount of hydrological and biological samples were taken in biweekly to monthly intervals at 14 study sites in 58 field campaigns. These data allow interesting insights into how the trees react to different climatic conditions in summer, since 2017 was particularly dry and 2018 particularly humid.
