Modern cities face a variety of environmental challenges. The greening of urban areas is becoming an important tool for improving the quality of life of the residents and increasing the sustainability of urban ecosystems. Plants are an integral part of urban infrastructure, performing a whole range of functions. Trees and shrubs, in particular, play a significant role in the formation of the urban ecosystem, the species diversity of which allows maintaining the ecological balance of the urban environment. This article examines the species diversity and the state of the dendroflora in the Podolsk urban district, as well as the impact of the urban environment on the viability of tree and shrub species. A total of 68 species of trees and shrubs belonging to 19 families and 37 genera were identified on the territory of Podolsk urban district. The most common families are the Rosaceae and Salicaceae. Among the trees of Podolsk, 25 species are indigenous, 43 are introduced. The analysis showed that 57.6 % of trees and 63.1 % of shrubs were in good condition, however, some green areas in the urban district required additional care and restoration. The average condition score for each species and the overall condition coefficient of trees and shrubs were also calculated. It was revealed that some of the tree stands and shrubs designated for general and limited use in Podolsk urban district were healthy, while others were weakened. It was revealed that some of the tree stands and shrubs of general and limited use in Podolsk urban district were healthy, and some were weakened. Monitoring the condition of green spaces helps to identify deficiencies in their infrastructure and contributes to the optimal management of this infrastructure, which, in turn, helps to create a comfortable and environmentally safe urban environment.
