ABSTRACT
Phytosociological studies on the littoral vegetation of the Zagłębocze Lake conducted in the summer or 1999 showed a considerable transformation or the phytolittoral. Extensive meadows with rare Lychnothamnus barbatus and Nitella flexilis disappeared completely. Formerly noted species: Chara mucronata, Myriophyllum alterniflorum (covering large areas) and other vascular plants were not found any longer. The place once occupied by vegetation with narrower ecological requirements was taken by photocenoses of Ceratophylletum demersi and Elodeetum canadensis; Phragmites austrialis superseded Potamogeton lucens, Scirpus lacustris and Heleocharis palustris.

Badania fitosocjologiczne roślinności jeziora Zagłębocze przeprowadzone latem 1999 roku wykazały dużą przebudowę fitolitoralu. Całkowicie zginęły rozległe łany z rzadką ramienicą Lychnothamnus harbatus oraz Nitella flexilis. Nie odnaleziono również wcześniej notowane gatunki Chara mucronata, Myriophyllum alterniflorum (tworzył duże powierzchnie) oraz inne rośliny naczyniowe. Miejsce roślinności o węższych wymaganiach ekologicznych zajęły fitocenozy Ceralophylletum demersi, Elodeetum canadensis, Potamogeton lucens oraz Scirpus lacuslris i Heleocharis polustris został wyparty przez Phragmites austrialis.
