The article gives a brief description of the synanthropic species, their classification, adaptive features, and the results of synanthropization of the vegetation cover. The author gives the data on the flora synanthropic species in Jewish Autonomous region (199 species, 13.8% of the regional flora), as well as their systematic structure analysis, life forms, ecological and geographical groups. It is shown the ways of distribution of synanthropic species over the territory. The results of original research on the introduction of these species into native forest communities are presented. It is defined the synanthropization index of forest plant formations (2.8% of the total number of identified species), and the synanthropic species - Celite Asiatic Chelidonium asiaticum (Hara) Krachulkova, which is predominant in the area.
