Some of these species are from the "black list" of invasive Elizaveta A. Devyatova 3* plants of Russia and some plants are usual for central Russia. These species were email: [email protected] introduced to the Kamchatka Peninsula and actively spread over the urban area in recent years. We assign communities with the dominance of the species under study to 2 classes of vegetation: Galio-Urticetea and Molinio-Arrhenatheretea.
