Abstract

Phytolacca acinosa Roxb. is a plant of East Asian origin actively naturalizing on the territory of Russia. The initial pathway of invasion of the species is “escape from cultivation.” Data from herbariums, digital databases, and field studies were analyzed, which made it possible to construct a map of the current range of the species. The lag phase of P. acinosa lasted from 1985 to the mid-2010s. At present, the species has successfully adapted to the environments of the European part of Russia, its invasiveness is increasing, and the number of new spontaneous populations is growing rapidly. The main site of invasion is Moscow, where the first spontaneous population was found in 2016, and by 2025, 115 local naturalizing populations have already been recorded, and the species occupies up to 20% of potentially suitable areas. A description of phytocenoses with P. acinosa is given, in which there are 45 species of vascular plants with a predominance of weedy species and a high proportion of alien species. The data on the structure of P. acinosa populations are presented, which is characterized by a high proportion of juvenile and immature plants—from 40% in the absence of disturbance and high grass canopy cover to 92% in anthropogenically disturbed habitats. Since P. acinosa is a synanthropic species and the area of landscapes under strong anthropogenic impact continues to grow, it is possible to predict further spread of the species and an increase in its abundance in the secondary distribution range.
