Fig. 6

Left panel: aboveground carbon (Mg C ha−1) and right panel: soil organic carbon (Mg C ha−1) in dependence of the beech-oak index (− 1 for 100% oak to 1 for 100% Beech relative basal area) for the three transects according to the model predictions. The adjusted R2 of the model fit is also given. The abundance of plots near an index value of 0 is caused by plots in which T. tomentosa forms pure stands
