The ecological-coenotic specters of the flora in the river Vyatka protected areas
The paper presents the results of a comparative ecological-coenotic analysis of 6 floras of the river Vyatka (Kirov Region, Russia). The floras of the studied areas are boreal and include rare and relic species of all-European importance. As for ecological structure the floras of the studied protected areas do not differ significantly and refer to 7 ecological-coenotic groups. Meadow and meadow-opening groups dominate in the revealed complex (28,48% to 41,84%). This may be caused by a systematic and strong anthropogenic impact on the protected areas. For example, trampling contributes to the increased invasion of meadow and meadow-edge species in forest ecosystems, where they take a significant part in the living ground cover, often acting as codominants with constant species of the grass-shrub layer of boreal forests. Less presented are wetland (13,61% to 27,15%), boreal (9,63% to 16,33%), nemoral (8,16% to 14,79%) and nitrophilous (8,16% to 13,33%) groups. The share of coniferous group varies from 4,44% to 7,10%. The oligotrophic group is presented by solitary species. The authors have also detected the correlation between the ecological-coenotic structure of the flora of the studied areas and the latitudinal location within the river basin.
