The study of biodiversity of anthropogenically disturbed areas is a prerequisite for assessing and predicting species abundance in regions. The present research aims at investigating the aquatic and coastal-aquatic flora and vegetation of the Sulem reservoir, built on the territory of the Visimsky nature reserve. Phytocoenotic material has been processed in accordance with the requirements of ecological-floristic classification of Braun-Blanquet. Flora analysis has been carried out in compliance with standard floristic methods. The study has revealed a variety of vegetation, which has been classified into 2 classes (Potamogetonetea and Phragmito-Magnocaricetea), 5 orders (Potamogetonetalia, Callitricho hamulatae-Ranunculetalia aquatilis, Phragmitetalia, Magnocaricetalia, Oenanthetalia aquaticae), 6 alliances (Nymphaeion albae, Potamogetonion, Ranunculion aquatilis, Phragmition communis, Magnocaricion elatae, Eleocharito Palustris-Sagittarion Sagittifoliae), 20 associations and 2 rankless communities. Communities of associationsElodeetum canadensis, Myriophylletum spicati and Callitrichetum hermaphroditicaeare the most common in the territory under study. Large areas are covered with Sagittario sagittifoliae-Sparganietum emersi, Typhetum latifoliae and Typha intermedia. Communities of associations Potamo crispi-Ranunculetum trichophylli, Potamogetonetum graminei, Potamo natantis-Polygonetum natantis, Typhetum angustifoliae and Sparganietum erecti are less common. Flora of vascular plants include 66 species from 43 genera and 26 families. Cyperaceae (10 species), Poaceae (8 species), Potamogetonaceae (6 species), Ranunculaceae (4 species), and Typhaceae (4 species) are the leading families. Hydrophytes prevail among ecological groups. Eurasian boreal species prevail in the geographical structure of the flora. 2 species listed in the Red Book of the Sverdlovsk region include Nuphar lutea (L.) Smith и Nymphaea candida J.
