Subject and Keywords:
The floristic composition of plant communities, their species richness, total diversity, evenness and dominance were studied in four uneven-aged old-fields (a Peucedano-Pinetum forest habitat) for three successive years. In the course of succession of the phytocoenoses the following were observed: (1) continuous directional changes in specific composition, (2) fluctuations of the values of the quantitative indices of structure, with a tendency towards lower levels of the indices of species richness, total diversity and evenness, a growth of the dominance index, (3) a fall of the rate of changes in the qualitative and quantitative structure characteristics, (4) a growing resistance of the communities to variable weather conditions.
