The object of the study comprises the biotic and abiotic components of the biogeocenoses of the Dnipro-Oril Nature Reserve. The aim of the work was to summarize scientific research on the condition of flora and fauna and observations of environmental changes within the reserve. The methods used included inventory and monitoring of flora, fauna, geological and geomorphological structure of the territory, establishment of scientific monitoring sites, phenological observations, and maintenance of a nature calendar.
General information about the reserve, scientific plots, profiles, and transects is provided. The course of the court case concerning the return of 133 hectares to the territory of the reserve is described; the case was lost due to the lack of documentary confirmation of the land’s inclusion within the reserve and the unresolved boundaries in the state cadastre. Data on water level observations in the Oril River and the Hruzska channel in 2025 are presented. The section on geology and geomorphology highlights studies of relic dune relief, erosion-accumulative activity of the Dnipro River, and the development of a geological-ecological trail within the reserve.
The section devoted to vegetation presents the results of studies on the plant cover of the first floodplain terrace of the Dnipro valley, the functional structure of aquatic macrophyte communities, and successional processes in meadow vegetation. High floristic diversity and the negative impact of the invasive species Amorpha fruticosa L. on meadow ecosystems were identified.
An inventory of fauna was conducted, and the state of mammal, bird, fish, insect, mollusk, and plankton populations was described. The work presents the results of long-term studies on the effects of eutrophication, hydrological changes, and climate warming on the functional structure of juvenile fish communities.
