The creation of natural lawns is a means of optimizing costs for maintaining green infrastructure in the city by including natural biodiversity in lawns, which will increase the stability of plant communities in lawns and the quality of ecosystem services. Purpose. Determine the predominant species of plant groups of natural phytocenoses, which are further appropriate for planting in semi-natural lawns to ensure the stability of territories.. Methods. The Ramensky method was employed to determine the quantitative composition of natural lawns in the study areas, while the Raunkiær classification was utilized to identify persistent and perennial plant species. Results. The geobotanical investigation enabled the identification of dominant species in the study areas, providing insights into the phytocoenological composition of natural lawns for the city of Kyiv. This served as the foundation for developing recommendations for a plant catalogue tailored to the creation of such lawns in Kyiv. The grass stand at Lysa Hora exhibited the highest stability, with a significant presence of native species. Adventitious species were less dominant in this area, likely due to their conditional pathogenicity. Conversely, Trukhaniv Island displayed dominance by typical species, albeit with the occasional presence of azonal species. Mount Shchekavytsia showed competition between azonal and typical species. Surveys of recreational areas, including Lysa Hora, Mount Shchekavytsia, and Trukhaniv Island, underscored the presence of native, azonal, and adventive species. The study identified common native hemicryptophytes, including filamentous fescue, grey fescue, and creeping wheatgrass. A developed plant catalogue is poised to enhance ecosystem regulation services, such as microclimate regulation, water and wind erosion control, biodiversity maintenance, and social services through increased territorial attractiveness. Conclusions. When creating a natural lawn, the best species are considered to be indigenous, which allows for the sustainability of plant communities. The study identified the following native species that will successfully complement lawn coverings in the city: gray and filamentous fescue, ground fescue, creeping thyme, green strawberry, field carnation, and oak sage. The recommendations can be applied in other cities of Ukraine with similar physical and geographical conditions.
