Change of the forest cover on the slopes oriented towards Lake Imandra lake under industrial pollution
Northern taiga and mountain birch forests were investigated on the slopes of Monche tundra and Khibiny Mountains (Murmansk Region, Russia) oriented towards Lake Imandra under long-term air-borne pollution from the metal processing industry. The subject of the study was the species composition and ty...

Northern taiga and mountain birch forests were investigated on the slopes of Monche tundra and Khibiny Mountains (Murmansk Region, Russia) oriented towards Lake Imandra under long-term air-borne pollution from the metal processing industry. The subject of the study was the species composition and typological diversity of vegetation along the pollution gradient at different altitudes above sea level. Three zones were distinguished – impact zone, buffer zone, and unpolluted zone as the control, 166 relevés were included in the classification that resulted in 15 groups of associations. The groups of associations were characterized; the area occupied and the proportion in the plant cover were given based on remote sensing data. Changes in plant diversity along the pollution gradient were assessed using the average number of species per 400 m2, Sørensen index, Whittaker index, as well as Shannon index. The activity of species (sensu Malyshev) was determined in groups of associations, and cluster analysis (with Euclidean distance) was undertaken to assess the similarity between the groups of associations.
