Summary:The problems of the extinction of aquatic plant species in Ivanovo region glacial lakes are discussed. As a result of research a sharp decrease in the number of rare hydrophytes ( Elatine hydropiper, Isoetes lacustris, I. echinospora, Sparganium gramineum ) has been established. The reasons are complex, they are associated with the eutrophication of ponds, heavy metals soil pollution, uncontrolled recreational loads and Elodea canadensis invaded into lake ecosystems. The ecological niche of Sparganium gramineum in the lakes is occupied by S. × longifolium , the hybridogenic origin of which is proved by modern molecular genetic analysis.
