Syntaxonomic, coenotic and ecological features of Rhamno-Prunetea class shrub communities of Podolia-Bessarabian Transnistria are considered in the current work. In the area of research three vegetation unions are presented: Prunion spinosae (communities usually formed on a more-less eroded loess soils of the gullies, where it often forms dense thickets of Prunus spinosa and herbaceous xeromesophilic species); Berberidion vulgaris (multispecies thickets of thermophilic species with a large share of steppe and woodside species growing on rich soils) has the most coenotic representation; Lamio purpureae -Acerion tatarici (group formed on the place of ravine forests in the outcrops of crystalline rocks). The characteristics of ten associations are given, one of which is an original description – Lembotropido nigricantis-Cornetum maris. The combination of xerophytic and mesophytic elements as well as different soil carbonate content describes conditions of the shrub communities’ formation, their ecological peculiarities and overall other characteristic aspects of the study region.
