The floral and phyto-assessment characteristics of wetlands are an important indicator for their monitoring. The territory of the Shatsky National Natural Park is a natural nucleus of the Polesia Ecology Corridor and a storing part of the AllEuropean Environmental Network. The preservation of the unique wetland complexes of the park requires constant monitoring of the most significant indicators that reflect their condition. The purpose of the studies was to generalize and analyse the flora of the higher vascular plants and vegetation of the park, justifying their use as monitoring indicators. The authors' field research on flora and vegetation was carried out during 2006-2020 on the whole territory of Shatsk NNP. Sixteen test sites were laid for detailed studies. Based on research and analysis of literature sources, 318 species of upper vascular plants belonging to 6 classes and 74 families were found in the flora of the park’s wetlands. Among the numerous families are represented typical for the natural floodplains of the wetlands of the Shatsk Lake: Cyperaceae, Poaceae, Asteraceae, Ranunculaceae, Lamiaceae, Potamogenaceae, Salicaaceae, Fabaceae, Polygonaceae. Species from «The Red Book of Ukraine» and species subject to regional protection in Volyn region are represented in the flora at the investigated sites. The vegetation cover of the studied territory is dominated by cenoses, primarily of marsh and forest vegetation types. Coastal-aquatic, aquatic and wetland groups of grasslands are well represented. Indicators for monitoring should be the dynamics of individual flora species and plant communities
