Descriptive statistics for the pure stands of Norway spruce and European beech, the mixed stands and the mixing effects on growth.Listed are for Norway spruce (sp) and beech (be) stand age of pure stands (agesp, agebe), dominant height of pure stands at age 100 (ho), periodic mean annual volume increment of pure stands (PAIV), ratio between productivity of spruce and beech in pure stands (PAIVsp:PAIVbe), mixing proportions (m), ratio between productivity of spruce and beech in mixed stands (PAIVsp,(be):PAIV(sp),be) mixing proportion of spruce and beech (msp,mbe); mixing effect absolute with respect to stand volume growth (MEAVsp,be), mixing effect relative with respect to dry mass growth of spruce and beech in the mixed stand (MERWsp,(be); MERW(sp),be) and the mixed stand in total (MERWsp,be).
