CHARACTERISTICS AND MAIN DIRECTIONS OF ANTHROPOGENIC FLOROGENESIS IN THE SOUTHERN VOLGA UPLANDS

The whole range of aspects of anthropogenic florogenesis in the southern part of the Volga Uplands is considered. Trends in the anthropogenic dynamics of local floras during the last 100 years are reported. A 50 - 100 km shift north of the southern boundary of the habitat of some boreal species (Antennaria dioica (L.) Gaertn, Maianthemum bifolium (L.) F. W. Schmidt, Pyrola rotundifolia L. etc.) is noted. Data on the adventive flora and contemporary migration paths of the plants in the area under study are provided.
