The syntaxonomic analysis of 94 geobotanical relevés of deciduous forests of the Right-Bank Ukraine with a rare species Scopolia carniolica was accomplished. They belong to the class Querco-Fagetea, order Fagetalia sylvaticae, alliances Alnion incanae, Tilio platyphylli-Acerion pseudoplatani, Asperulo-Fagion, Cephalanthero-Fagion, Carpinion betuli, and to 19 associations. Maple-lime-ash forests on stony soils of the alliance Tilio platyphylli-Acerion pseudoplatani are the phytocenological optimum of S. carniolica on study area. In contrast to Central Europe, S. carniolica in Ukraine is not present in heliotermophilic and acidophilic-mesotrophic syntaxa; in contrast to the Caucasus, it is absent in Alnus glutinosa forests.

The composition of dominant species in syntaxa with S. carniolica is generalized. The phytocoenotic range of the species in Ukraine is defined, which allows to predict its presence in other syntaxa. The analysis shows that among the co-edificators, most of the subdominants of the stands are in the formations Fageta sylvaticae, Fraxineta excelsioris, Querceta roboris, and Q. petraeae. It has been found that the formation Carpineta betuli contains the largest number of semi-edificators that usually do not act as edificators. Thus, S. carniolica occurs in a variety of deciduous forests in the country. The species is rarely observed in Ukraine in the forests of the formation Alneta glutinosae. A syntaxonomic inventory of the localities of S. carniolica will contribute to composition of syntaxa in the next edition of the Green Data Book of Ukraine as well as improve the protection of the species.
