45 alien species belonging to 17 families and 32 genera were identified. All of them are introduced species. The primary ranges of species cover mainly the adjacent territories of East Asia (13 species, or 28.9%) or North America (11 species, 24.4%). Most species are not naturalized and are found only in culture (40 species, or 88.8%). There are only five naturalized species – Acer negundo, Hippophae rhamnoides, Microcerasus tomentosa, Pinus sylvestris, Ulmus pumila. In terms of life form, summer green trees and shrubs predominate. It was concluded that the alien fraction of the dendroflora of Khabarovsk is a temporary, non-permanent component that does not affect the structure of the native flora.

Keywords:dendroflora of the city, species composition, primary habitat, degree of naturalization, Khabarovsk
