Urban green spaces introduce elements of nature into the city, preserve the connection of man with nature, and expand urban landscapes. Introduction and acclimatization is the basis for the selection and successful introduction of economically valuable plants into the culture. A limited floristic assortment of local dendroflora determines the relevance of the introduction of trees and shrubs in the Arkhangelsk region. Arboretum named after I.M. Stratonovich was created in Arkhangelsk to study the acclimatization and introduction of plants from the southern regions to local conditions in northern Russia. Representatives of various geographical areas are gathered in the arboretum in a limited area. There are about 200 species from 50 genus and 19 families. Resistant plants to the conditions of the northern climate are selected. The range of woody species at the main objects of landscape architecture of Arkhangelsk was studied and analyzed. Conducted research expands the scientific and informational level of knowledge about the possibility of moving to the North economically valuable tree and shrub species. This will positively affect the biodiversity of the north dendroflora.
