Anthropogenically disturbed communities can be a source of introduction of alien plants into less disturbed adjacent communities. The purpose of the work was to assess the degree of adventitization of forest communities of the Kalinovsky Forest Park (Yekaterinburg) near different sources of propagules of nonforest plants. 24 sample plots of 20×20 m were surveyed: on the borders with garden plots, on the borders with the railway, inside the forest park. It was found that the average number of alien species was 7 times greater near garden plots compared to other options. The cumulative richness of alien species near garden plots was also almost 5 times higher compared to other options.
