This article considers the problem of changes in phytodiversity under the influence of invasive species on the example of communities dominated by Acer negundo L. Acer negundo is one of the most aggressive adventive species, its edificatory impact on forest communities determines the high level of research interest in monitoring this process. This article examines the dynamics of changes in the floristic composition of a floodplain forest within the "Galichya Gora" Nature Reserve over a fifteen-year period. Despite the widespread notion of an irreversible decline in species diversity in plant communities dominated by adventive species, the presented facts indicate that these predictions are not always consistent with the actual state of the plant community. Despite the stable presence of Acer negundo, the total number of species didn’t change significantly. In the herbaceous layer, the participation of species from the nemoral ecological-coenotic group increased twofold. Although the high crown density and intensive regeneration of Acer negundo under its own canopy hinder the introduction of native tree species, this doesn’t act as a limiting factor for the development of herbaceous plant populations characteristic of broad-leaved forests.
