Changes in littoral flora as well as aquatic and swamp vegetation were analysed with increasing eutrophication of the mesotrophic Lake Mikolajskie. Over 30 years the habitat conditions of the lake deteriorated and the phytolitoral was reduced from a zone 6 meters wide to one of only 2 meters. The number of submered macrophyte species decreased by 50 percent and the frequency of most of the remaining species declined severalfold. A significant lowering species declined severalfold. A significant lowering of the phytosociological diversity and species richness was observed
