Abstract: * The influence of tree species diversity and functional group on soil properties (carbon stock, pH and C/N ratio) has not been explored across major European forest types.  * We evaluated the relative importance of tree species diversity and functional group for soil carbon (C) stocks, C/N ratio and pH in major European forest types in the six regions Finland, Poland, Germany, Romania, Italy and Spain. We sampled soils in 209 permanent plots along a species diversity gradient from monocultures to five-species mixtures.  * Carbon stocks in the topsoil (forest floor (FF), 0–10 cm and FF + 0–10 cm) were positively, but weakly, related to diversity across the regions. While the C/N ratio in the FF + 0–10 cm layer decreased significantly with increasing diversity in the Spanish region, pH was unrelated to species diversity across the regions. Tree species functional group (in terms of conifer proportion, CP) explained a larger proportion of the variability in soil properties than diversity. Conifer admixture increased C stock and C/N ratio, and decreased pH, but the impacts differed between the regions in some layers. Differences in mean annual temperature, actual evapotranspiration and soil texture between the regions were possible driving factors behind the different CP effects in Finland, Spain and Germany.  * The results imply that targeted selection of tree species with desired characteristics, e.g. complementary traits for resource use, is a preferred management approach for influencing soil C stock, C/N ratio and pH in mixed forests rather than increasing tree species diversity per se.  A lay summary is available for this article.
