The study considered the issue of inventory and assessment of the state of Aesculus pavia plantations in urban conditions using the example of the city of Vinnytsia, which is an important stage for the development of recommendations for improving the phytosanitary condition of green areas and the selection of sustainable species for landscaping. The inventory of plantations was carried out during the growing season of 2024, with the recording of 18 instances of Aesculus pavia, mostly concentrated in the Vyshensky District. The majority of trees are located along transport routes and are under 25 years old (56.5%), while trees aged 41–50 years account for only 8.9%. The assessment of the state of life using the visual analysis method, taking into account the condition of the leaves, the presence of mechanical damage, dry branches and pests, showed that a significant proportion of the trees are in good condition (64.5%). At the same time, trees near roads suffer from “burns" of leaves due to overheating of the soil, insufficient watering and technogenic stress. Special attention in the study is devoted to frost resistance and drought resistance of the Aesculus pavia, which are key to the survival and effective use of the species in the urban environment. Research conducted in the agrochemical laboratory proved that the Aesculus pavia is able to withstand frosts up to -25 °C, while the greatest damage is observed in the buds. Studies of drought resistance based on water retention coefficients in different areas of the city have shown that the man-made load leads to an increase in water deficit. In the most polluted areas, the coefficient of water retention and drought resistance decreases, which impairs the viability and decorativeness of trees. The results of the study indicate a high perspective of the introduction of Aesculus pavia in urban conditions, in particular in Vinnytsia. This species retains decorativeness, and is also resistant to frost and partially resistant to man-made stress, which makes it a valuable element of landscaping, able to integrate into the cultural landscape of the city and contribute to the creation of natural fragments in the urban environment.
