The article presents the analysis of the results of the floristic study of aboriginal woody plants growing within the administrative boundaries of the city of Khabarovsk. It has been established that aboriginal species form the basis of the city dendroflora, which is due to the geographical location of the city in the zone of Far Eastern coniferous-deciduous forests, characterized by exceptional richness and diversity of the species composition of trees and shrubs, an abundance of woody vines and epiphytes. 101 species of woody plants belonging to 28 families and 51 genera have been identified. The leading positions are occupied by four families Rosaceae, Salicaceae, Betulaceae, and Pinaceae. They contain almost half of the aboriginal species (50 species, or 49%), subject to progressive processes of apophytization. At the same time, the high content of single-species families can be associated with the low adaptation of aboriginal woody species to the conditions of the urbanized environment. This feature can be considered an indicator of anthropogenic transformation of natural dendroflora in an urbanized environment. Urban forest stands are represented by tall trees and shrubs that form two- and three-tiered plant communities. Representatives of the heat-loving Manchurian Forest flora are present – woody vines and an epiphytic semi-parasite. The grid mapping method showed that most species are common in frequency of occurrence, distributed evenly across the city. The species diversity of woody plants is concentrated in outlying areas that are in direct contact with natural forest vegetation, and in the central part of the city it is concentrated in forest park zones. Most woody plants grow in natural and semi-natural urbanized habitats and are also successfully cultivated. A predominance of species with East Asian types of range is observed (82 species, or 81%), which indicates autochthonous processes in the formation of Khabarovsk dendroflora. It is a synanthropized analogue of the regional flora. It does not include species with a wide cosmopolitan and Holarctic distribution. Due to the significant tolerance of many local species of woody plants to anthropogenic impact, it is proposed to expand the range of native species in the improvement of the urban environment.
