Information on projective coverage and species composition of coastal and aquatic phytocenoses is provided. It was found out that coastal and aquatic vegetation predominates territorially. Coenoses of aquatic vegetation mostly represent different stages of overgrowth of water bodies. The distribution of plant communities has been clarified and a comparison of the representation of the classes of higher aquatic vegetation of reservoirs of Chernihiv Polyssia has been made. Plant groups with a species composition and structure typical of Polish vegetation were identified. The classification scheme of plant syntaxons is based on the floristic and ecological approach. Groups of higher aquatic vegetation of the analyzed territories are represented by 24 associations belonging to 8 unions, 4 orders and 3 classes. The greatest phytocenotic richness and diversity is noted in the class Phragmito-Magnosaricetea.
