 We carried out the structural and comparative analysis of the floristic composition of communities of gully systems and slopes of aboriginal banks of the Inhulets River. In the adventive fraction of urban flora of Kryvyi Rih, an invasive component was identified – 126 species from 101 genera and 45 families, among which 15 species from 7 families are characterized by the highest invasive activity. We determined that the morphostructural and biomass parameters in Festuca valesiaca, Marrubium praecox, Convolvulus lineatus and Stipa capillata showed an indicative ability for climate change. It was found that due to climate destabilization in the steppe zone of Ukraine, the area of tree and shrub phytocenoses increases due to the reduction of grass ones. A specific phenological response of many steppe plants to abnormally high temperatures in the autumn period of 2020, accompanied by re-blooming in early flowering species, prolonged flowering and autumn regrowth after the end of the growing season. These manifestations are considered as indicator signs of climatogenic changes. According to the research results, the main directions and ways to optimize the protection of rare and endangered plant species in the Inhulets basin have been identified. We developed the preventive measures to preserve phytodiversity and minimize the destructive impact of aggressive alien species on aboriginal ecosystems. It is proved that perennial ornamental plants respond to changes in air temperature and hydrological regime by shifting the timing of the beginning of the main development phases and their duration. Peculiarities of the vegetative sphere development of Hemerocallis L. varieties and species of the genera Oenothera L. and Veronica L. during seasonal development were manifested in change of morphometric parameters of the leaf, in the anatomical structure of assimilation apparatus as well as in development of the root.
