Invasive plant species as a cause of delay of restorative succession
The features of communities of alien species-transformers, capable of blocking regenerative successions, are studied. The process of delay of succession is considered in the example of <i>Solidago canadensis</i> L. and <i>Acer negundo</i> L. Typical habitats of communities of alien transformer species are deposits and wastelands with non-extremal moisture, pH and nitrogen richness edaphotopes. The overwhelming majority of the identified phytocenoses with the dominance of alien transformers are confined to the old anthropogenic landscapes.
