The Experiment Working Group of the Action brought its first deliverable to the table. We set up a network of European forestry experiments that investigate the effects of various forestry treatments on multi-taxon biodiversity.
Experiments – Opportunity to gain fine-scale information
Experiments are very diverse. They investigate various treatments, are carried out in various ways, at various spatial scale and with various design. It is hard to merge them into a uniform database. Why do we still try to combine them? What additional value can they add to the observational studies included in the Bottoms-Up platform? The answer can be found in the fine spatial scale at which they provide direct information on the effects of a given forestry intervention. Moreover, they often focus on innovative management strategies that are underrepresented across the network of observational studies.
What was our aim?
We collected data from experiments based on forest stand manipulation (different types of cutting, microhabitat creation, etc.) in which the response variable was multi-taxon biodiversity, i.e., the diversity of at least three organism groups. Because of the above-mentioned heterogeneity, our first goal was to give an overview about the existing (and planned) experiments, and to define overlapping topics based on this information. These topics can be then subjected to joint analyses. Additional measurements can be also planned across different experiments to enhance the degree of overlap between them.
