The paper presents the taxonomic composition of 23 quarters with the identification of dominant plant forms and an assessment of the sanitary condition of plants by category. The taxonomic composition of tree and shrub plantations is represented by 42 genera, 22 families of 14 orders from the departments – Gymnospermae, Angiospermae. Of the identified 22,489 trees and shrubs, 89.6% are deciduous and 10.4% coniferous. The greatest taxonomic diversity was noted in the families Rosaceae and Pinaceae.
