The study has shown reproductive peculiarities of species and forms of the genus Robinia L. for forecasting the risks of their use in artificial plantations, and the ranking by the status of their invasive activity was carried out. It is found that in the conditions of Volgograd region Robinia pseudoacacia f. pyramidalis (Pepin) Rehd. and R. pseudoacacia f. umbraculifera (DC.) Rehd. are not capable of blooming and bearing fruit, as well as of forming stable self-seeding artificial plantations. Recommendations on prevention of invasive activity of introduced species during planning and reconstruction of artificial plantations are given.
