Results of the analysis of the species composition of invasive flora of the Russian Black Sea coast presented. Bioclimatic and ecological and geographical requirements for the most aggressive invasive species are given. Most subjects of invasive species naturalized in the south of the Russian Black Sea coast, historically confined to the biome deciduous temperate forests. Bioclimatic conditions of the south of the Russian Black Sea coast are suitable for the majority of alien species that creates the preconditions for the further spread of these species in the course of human development of the territory. As a result of climate change conditions in the south of the Russian Black Sea will become even more comfortable for the spread of invasive species.
