Aim. The aim is to assess the changes in the nitrogen regime of park ecosystems in Kyiv by tiers due to the supply of nitrogen with atmospheric precipitation. Methods. Applied methods of forestry, geobotany, phytoindications. Results. We have analyzed the number of nitrophilic stenobionts of woody vegetation and grass cover. The eutrophication trend is the same for both tiers of the studied ecosystems. Although in the grass cover the proportion of nitrophils is greater than in the woody one. In the natural boundary Lysa Gora nitrophil content is the highest among the studied ecosystems of the park (70% in the grass cover, 58.3% in the woody vegetation). Conclusions. Thus, 50% of the parks are in critical danger, 30% are in a threatened state, only the Pushcha-Voditsa parks are in a stable condition. A significant number of nitrophilic stenobiots were found in Kyiv parks (50–70%), and the grass cover is more plastic in terms of environmental changes than the tree.
