Features of flora species composition in communities with Acer negundo in Kuzbass

Abstract

The article presents the study results of the species composition of vascular plants in phytocenoses with Acer negundo located in the mountain-taiga and forest-steppe zones of Kemerovo Oblast. We have identified 41 species of vascular plants from 36 genera and 17 families. Under the canopy of A. negundo, ruderal species (Cirsium setosum, Elytrigia repens, Urtica dioica) prevailed, however, beyond this zone the number of meadow species (Achillea millefolium, Dactylis glomerata, Festuca pratensis) increased. Species diversity in the plant communities with box elder involvement was on average 55% lower than in those where this species was absent. In the mountain-taiga and forest-steppe zones, species diversity of plants declined by 1.7 and 2.8 times, respectively.
