Occurrence records of vascular plants from steppe gully systems (Mayorska valley, Dnipropetrovsk region, Ukraine, 2023)

A total of 289 sample plots (4 × 4 m) were surveyed, resulting in 263 vascular plant species recorded. The dataset represents steppe vegetation islands preserved within gully landscapes, which play a crucial role in maintaining biodiversity in the agricultural matrix of southern Ukraine.

The data can be used for analyses of species richness, hemeroby, naturalness, functional diversity, and as a baseline for monitoring vegetation changes under climate change and land-use transformation. The resource contributes to the knowledge of steppe flora in Eastern Europe and supports conservation and restoration planning for gully ecosystems, which act as important refugia for native steppe species.
