Analyzing size-symmetric vs. size-asymmetric and intra- vs. inter-specific competition in beech (Fagus sylvatica L.) mixed stands
Abstract
Size-asymmetric competition is stronger than size-symmetric one in studied mixtures. Beech benefits from pine and oak admixtures, more when the latter are larger trees. Beech has a negative effect on pine growth and a variable effect on oak growth. Fir and beech basal area growth is not modified by species admixture. Species mixing can reduce competition on smaller trees, improving stand stability.
