Plant survey data from Khortytsia Island (Ukraine), 2025

The data come from plot-based vegetation surveys aimed at documenting the response of floodplain and coastal plant communities to the altered hydrological regime after the destruction of the Kakhovka Reservoir in June 2023.Sampling was carried out in floodplain lakes and along the exposed outer shoreline of the island in areas that experienced the strongest changes in water level.

At each sampling plot all vascular plant species were recorded and their cover or abundance was estimated using standard phytosociological (Braun–Blanquet) methods. Each record in the dataset corresponds to the occurrence of a plant species in a particular plot, with associated information on date, locality, coordinates (WGS84) and basic habitat characteristics. The dataset is intended to provide a baseline for analysing vegetation dynamics, hemeroby and naturalness gradients, and for supporting future monitoring and restoration planning in the Lower Dnipro floodplain ecosystems.
