Mean carbon content (kg/m 2 ) in tree stands (below-ground parts included) ofthe forest study area on Olkiluoto main island by site types and age class (based oncalculated biomass distribution on FET plots and carbon coefficient estimate 0.50). Sitetypes: grove, grove-like, fresh, dryish, dry and extremely infertile mineral soil types, allwith corresponding mire and drained peatland types. Rocky soils also include finesandy soil and stony soil. Finnish site type abbreviations appear in parentheses.
