Journal Title: Наукові доповіді НУБіП України - Year 2017, Vol 4, Issue 4
Abstract
The composition of the shrub vegetation of the Northwest Black Sea region within the middle and southern steppe sub-regions were studied. The species composition of the shrubs is represented by 18 species that belong to 12 families. The main distribution of species of shrub vegetation by groups in relation to environmental factors has been characterized. Mesophytes, mesotrophs and scygeleophytes predominate on the territory of the middle-steppe subzone with attitudeto the conditions of growth, the situation is some different in the territory of the south-steppe subzone. Xeremosophytes, mesotrophs and heliophytes predominate here. The present state and status of natural shrub vegetation in the conditions of the steppes are determined. The obtained results of the research were subjected to comparative generalizations with the data on the species structure of the shrub vegetation of the Black Sea steppes, known prior to the beginning of the 20th century.
