Aim. The analysis of the taxonomic composition and living condition of tree plantations of roadside strips in Kyiv. Methods. Determination of the species composition and viability of trees and shrubs was carried out by route survey on test areas along the routes with different traffic intensity. The plants living condition was established according to the methodology developed by us, which provides an integrated vitality assessment based on a set of morphometric, reproductive and phenological features. Results. It is established that in the conditions of traffic flow of high intensity 23, of moderate 27 and of low 29 species of trees and bushes were found on the test areas. The tree plants of most common genera and species of roadside plantations are identified. The plants living condition analysis showed, that in the conditions of traffic flow of high intensity, plants of moderate and low vitality predominate; while in the conditions of moderate and low traffic intensity, the predominant numbers of plants have high vitality. Conclusions. Analysis of the range of roadside plantations indicates its limited and almost complete absence of conifers. The species composition is not optimal and is not always determined by the degree of resistance to transport pollution specific conditions. The woody plants vitality is largely determined by the traffic intensity and compliance with care technology.
