Abstract
Trends in the anthropogenic transformation of the taxonomic structure of the native flora in the southern Volga Uplands (within the Saratov region) are analyzed. The temporal dynamics of this structure in three local types of flora was studied over the past 100 years. The degree of tolerance of the flowering plant taxa in the studied flora to the full range of anthropogenic habitats and to their individual types is shown. The proportion of species characterized by anthropogenic geographical migration was estimated for each taxon. It is suggested to use the percentage ratio of species in the Magnoliophyta classes as an indicator of the degree and stage of anthropogenic transformation of the flora.
