VEGETATION DIVERSITY IN FLOODED QUARRIES OF SOUTHERN KARELIA
The results of our investigation of diversity of vegetation in flooded quarries of the Southern Karelia are presented. 167 vascular plant species and 42 bryophyte species were found in the flooded quarries. 16 vegetation associations were distinguished by the analysis of 293 sample plots using ecological and phytocoenotical approach. Diagnostic species are determined for each association; species richness and density are counted as well as the numbers of highly and medium constant species. The article also contains detailed descriptions of some associations.
