Changes in forest structure, composition, and management regimes over time affect the temporal variation of biodiversity. Therefore, the results from studies on forest biodiversity conducted at single time scales may not be transferable to all the development phases of a particular stand. When no experimental plots are available for long-term observations, artificial time series may be established by combining stands of different ages. Artificial time series have been used for recording the growth of even-aged stands to construct yield tables. We established a similar growth series of even-aged stands that included about 2000 plots distributed across Europe within the framework of the COST Action BOTTOMS-UP. This allowed us to assess the relationship between management regime, structure, structural diversity, species richness and abundance of several taxa over time. The results contribute to bridging the gap between the increasing amount of knowledge about stand structure processes and the information deficit in how multi-taxon biodiversity changes with them.
