Botanical gardens in Russia, akin to botanical gardens worldwide, face a significant responsibility: to monitor phytoinvasions and prevent the dissemination of invasive plant species. The International Botanical Community has prioritized the conservation of biological diversity to manage the process of plant invasion at national and regional levels, targeting at least 100 of the most aggressive alien species that harm native plants, plant communities, and biocenoses. In 2011, during a conference in Yaroslavl, the Council of Botanical Gardens of Russia adopted the Code of Conduct for Invasive Alien Species in Russian Botanical Gardens, which addresses staff at nurseries and horticultural centers, botanical gardens, arboreta, visitors, volunteers, landscape architects, and government authorities. Currently, the Moscow Government has commissioned experts to develop measures aimed at reducing invasive species in urban landscaping. An expert group (the authors) compiled a list of 32 high-risk invasive plant species in Moscow, recommended for eradication from all specially protected green areas. Furthermore, five transformer species established in Moscow should be phased out; among these, Ambrosia artemisiifolia and Ailanthus altissima, expected to appear imminently, must be eradicated immediately upon detection. Fourteen species are proposed for exclusion from urban landscaping due to their propensity for escape and spontaneous invasive population formation. Additionally, eleven invasive herbaceous species require population control and partial removal within zones of high ecological impact.
