In todayʼs environment of urbanization and environmental degradation, it is important to preserve and rationally use urban green spaces. Street plantings perform environmental, sanitary, social, and aesthetic functions: they improve the microclimate, reduce noise, and purify the air. However, due to technogenic and anthropogenic factors, trees are often in a depressed state, requiring constant monitoring and scientifically based care. The study was conducted within the urbanized environment of Bila Tserkva using spatial, phytosanitary, and taxonomic characteristics of green spaces. Primary data on the location, species composition, and condition of trees were obtained from the «Smart Green BC» geoportal. The condition of public green plantations, including street trees along main roads, was assessed. We identified 4281 greening objects, including 3163 trees. The area of green spaces per capita is 3.1 m², which is significantly below the standard of 7–10 m². The species composition is diverse, dominated by the families Rosaceae, Salicaceae, Oleaceae, Aceraceae, Fabaceae; the most common species are Platanus orientalis L., Populus italica (Münchh.) Moench, Acer platanoides L., Robinia pseudoacacia L. According to the Kuznetsov scale, more than 48% of plantations require restoration. The main threats are mechanical damage, air pollution, soil compaction, and irregular maintenance. The spread of pests and pathogens also negatively affects the phytosanitary condition. The practical significance of the study is to provide information for effective management of urban greenery, making informed decisions on plantation renewal, which will contribute to increasing environmental sustainability and life quality of residents.
