Qualitative analysis of vegetation along the Polish coast was conducted. Thirty-six species were noted - 16 of green, 5 of brown and 7 of red algae and 8 of vascular plants. In the 1996-2000 period, the share of green algae was always more than 50% of the floral composition. Only a few species were present throughout the period of investigations, as follows: green algae - Enteromorpha ahlneriana, E. intestinalis, Cladophora albida, Cl. glomerata, Cl. rupestris, Cl. sericea, Cl. vagabunda; brown algae - Pilayella litoralis, Fucus vesiculosus; red algae - Polysiphonia violacea, Ceramium diaphanum; vascular plants - Zostera marina. Some general conclusions can be drawn with reference to the geographical distribution of the species. Enteromorpha intestinalis was the only species that occurred at every station in almost every year. Three species of the genus Cladophora (Cladophora albida, Cl. rupestris, Cl. sericea) and Pilayella litoralis were also very common. Zostera marina was nearly absent from the central part of the Polish coast. Other species occurred rarely and accidentally.
