Of late decades, numerous studies on vegetation dynamics have been carried out and the spectrum of studied objects extended. However, syntaxonomy, while is capable to reveal patterns in vegetation changes, is virtually not used in analysis of succession. Prospects of syntaxonomy application to the study of vegetation dynamics are demonstrated by the example of succession analyses of pasture digression, vegetation changes under influence of recreation, progressive succession at the place of deserted settlements. The special role played by the analysis of syntaxonomic spectre of serial plant communities is discussed. The analysis makes it possible to estimate the serial status of communities by the ratio in their floral composition of species from cenofloras of classes that represent different serial stages of vegetation.
