Study of native dendroflora of Khabarovsk city

Abstract

The problem of studying the dendroflora of cities is relevant when conducting modern ecological andbotanical research. The article presents the results of an inventory of native dendroflora of the city of Khabarovsk. Anannotated list of 116 species from 27 families was compiled, which exceeds the corresponding figures for the dendrofloraof Vladivostok and Birobidzhan. At the same time, the dendroflora of Komsomolsk-on-Amur, Blagoveshchensk,Petropavlovsk-Kamchatsky is much richer in terms of plant composition. Taxonomic, general, and biomorphologicalanalyzes of the flora have been carried out. The leading botanic families have been identified: Rosaceae, Salicaceae,Betulaceae, Caprifoliaceae. Large species are: Salix, Acer, Betula, Lonicera, Ulmus, Picea, Populus, Ribes, Spiraea, Rosa,Euonymus. Among woody plants, East Asian species predominate, which corresponds to the position of the city ofKhabarovsk within the Manchurian region of the East Asian floristic region. The nemoral group is the richest in species,which is typical for broad-leaved and coniferous-broad-leaved forests of the temperate zone. Analysis of life forms andrhythms of annual development show the predominance of summer-green shrubs, evergreen and summer-green trees inthe flora of the city. There is a small number of lianas, dwarf shrubs. Dwarf forms in the dendroflora of the city are rare,they are found on the territory of the Far Eastern Forestry Research Institute‘s Arboretum. There is rare and protectedspices in the flora of the city – Taxus cuspidata.
