XVI International Botanical Congess
The assessment of flora's restoration potential is necessary for prognostication of its further development. The most important index for evaluation of the potential is a species successional status. It is defined by its place and phytocenotic role in the whole complex of rows of digressive and restoration vegetation changes. In the south-east of Ukraine the flora of pastures embraces steppe, meadow and saline communities. On the basis of the developed scheme of species habitats and classification of a species successional status the restoration potential of the most distributed ravine steppe pastures on the black soils were established. In this flora species-differentiators of final stages (38%) prevail, which testifies to a significant degree of communities transformation.20% of species-pioneers witness about the potential for restoration.
