Abstract
The article presents the results of a comparative study of the flora of 54 small and medium-sized cities in the Russian Federation. The main predictors of species richness, such as area and population size, have been identified, the universal pattern of increasing the species richness of urban flora is confirmed. The average species richness of the flora in small and medium-sized cities is 522 species, which is lower than the average for cities with a population of over 100,000. The importance of geographical location in shaping species richness has been demonstrated, with the highest number of species found in the floras of small and medium-sized cities located in the forest-steppe zone. The dependence of the proportion of alien species on the geographical latitude of the area, average temperature, and altitude above sea level has been established. The proportion of alien species in the flora of small and medium-sized cities is lower than in the flora of large, major cities, and million-plus cities. A common feature of the flora of small and medium-sized cities is revealed: the predominance of native species. Practical recommendations of nature-protection character are given.
Key words
Urban flora, plant species richness, native species, alien species.
