Growth dominance of beech as relationship between cumulative biomass and cumulative biomass increment in forest reserves (red) and respective management areas (green). The indication “A” points to a situation where the smaller trees representing 40% of the cumulative biomass are providing less than 25% of the cumulative biomass increment in the forest reserve, but about 40% of cumulative biomass increment in the management area. At “B” individuals that represent 80% of the management area’s biomass contribute to about 77% to the stand’s biomass increment. At “C” the smaller trees of the forest reserve, representing about 20% of the cumulative biomass, are providing about 30% of the cumulative biomass increment. At “D” the individuals of the management area contributing 50% of the stand’s biomass account for little more than 30% of the stand’s biomass increment
