Currently, phenology is actively used to display and study the effects of climate factors and human impacts on ecosystems. Researchers described phenological responses of plants to climatic and anthropogenic changes, as well as phenological features of alien species, as a factor determining the success of the invasion. In Komsomolsk-on-Amur (Khabarovsk region, The Far East of Russia) a database on the blooming of plants for the city residential areas and Silinsky forest was compiled on the basis of photo archive of plants. Silinsky forest is undisturbed woodland in the city. The flora of the Silinsky forest consists of 378 species of blooming plants, of which 329 plants are native species, 49 ones are alien species. The flowering plants flora of the residential areas of Komsomolsk-on-Amur consists of 518 species: 264 species are native, 254 ones are alien. Blooming was counted for decades. Comparative assessment of blooming periods was conducted for native and alien species taking into account their range and eco-phytocenotic preferences. There is a smoothing of typical features for the region in the more disturbed residential area. The alien fraction contributes to this. The June peak of blooming is disappearing, there is a shift of blooming to the end of summer. Thus, the phenological characteristics of the community can be used as an indicator of anthropogenic pressures.
