To the analysis of qualitative indicators of plant vitality in assessing the value of urban green spaces

Abstract

The decrease in the plant vitality, and, therefore, the functionality of urban green spaces caused by a sharp deterioration in the growing conditions and the non-observance of scientifically based principles of planting planning and an absence of a reasonable plant material selection for specific objects. An unsystematic increase in the species and cultivar diversity of ornamental trees and shrubs occurs spontaneously, without considering the consistent work on introducing and cultivating new species and varieties. The use of imported, not adapted, and often poor-quality planting material leads to a decrease in the survival rate of new plantings and, as a consequence, to a deterioration of the condition of a green space in general.
