Abstract
The paper presents the results of the investigation of successional processes in vegetative cover arising during succession started after underflooding of genuine and wet meadows in Tuva Central Basin. Stressor-initiated successional processes, i.e. initiated by inundation and overmoistening caused by the operation of the Sayan-Shush hydroelectric power station, transform vegetation to meadow and to wetland. Over the 16 successional years plant communities were completely replaced after inundation, only marshy meadow communities remained. The early succession stage and developed glycophyte meadow communities, marshy meadow areas. Standing crop of above-ground plant mass of steppe meadow and meadow areas from 783 g/m2 in 16 years old 166 g/m2. The change of damp meadow areas is no consequence.
