✦ Synopsis
The study area in the BialowieZa primeval forest -size 28 000 m 2, divided into quadrats of 100 m 2, comprised two patches of Potentillo albae-Quercetum as distinguished by phytosociological methods, and a fragment of an adjacent very large Tilio-Carpinetum stand. The directional variation in the distribution of Carpinus betulus trunk diameter values in the southern part of the study area indicates invasion of this oak forest by Carpinus. This process probably started 1962-1968. The invasion of Carpinus betulus caused considerable deterioration in light conditions of the ground layer, as deduced from a decrease in Ellenberg light index values.
The phytosociological division of the study area correlates with variation in the spatial pattern of Carpinus mean trunk diameter distribution.
Quadrat groups were distinguished by association analysis. They were described phytosociologically using systematic group values for species, constituting the characteristic combination for the Potentillo albae-Quercetum. Areas occupied by still older Carpinus individuals correspond to successive stages of oak forest regression. The deterioration of light conditions caused recession of thermo-and heliophilous oak-forest species and decline of Potentillo albae-Quercetum phytocoenoses. However, this was not accompanied by the expansion of species of Carpinus forests.
