The Biodiversity Exploratories are long-term research sites established to advance biodiversity research in Germany. So called core projects provide infrastructure and manage long-term monitoring. From one of these core projects inventory stand data of nearly all forest plots are available.

Unfortunately, we mistakenly believed that these data could be used by the scientific community of the exploratories. Even more unfortunately, we realized not till publication of the online version of our article “Quantifying forest stand management intensity in Central European Forests” that we were not allowed to use the data. We are very sorry for this mistake which was truly unintended and we herewith explicitly apologize for our misunderstanding. Therefore we, the authors Peter Schall and Christian Ammer, retract the article.
