Abstract

Forest soils contribute ca. 70% to the global soil organic carbon (SOC) pool and thus are animportant element of the global carbon cycle. Forests also harbour a large part of the globalterrestrial biodiversity. It is not clear, however, whether tree species diversity affects SOC. Bymeasuring the carbon concentration of different soil particle size fractions separately, we wereable to distinguish between effects of fine particle content and tree species composition on theSOC pool in oldgrowthbroadleavedforest plots along a tree diversity gradient (1,3and5species).Variation in clay content explained part of the observed SOC increase frommonospecific to mixed forests, but we show that the carbon concentration per unit clay or finesilt in the subsoil was by 30–35% higher in mixed than monospecific stands indicating asignificant species identity or species diversity effect on C stabilization. Underlying causesmay be differences in fine root biomass and turnover, in leaf litter decomposition rate amongthe tree species, and/or speciesspecificrhizosphere effects on soil. Our findings may haveimportant implications for forestry offering management options through preference of mixedstands that could increase forest SOC pools and mitigate climate warming.
