Uwagi do wystepowania zycicy trwalej na lakach i pastwiskach Niziny Szczecinskiej i Pobrzeza Baltyckiego

The results of phytosociological observations and investigations conducted on the Szczecin Lowland (on polder complexes at the Dąbie Lake, the Szczecin Bay, on pastures located in small river lowlands) and on the Baltic Sea shore (on the Trzęsacz and Niechorze polders) in the years 1964-2001 are presented. Following the sowing of grass mixtures with Lolium perenne, the species with drew from meadows placed on muck-peat soils after some years; it retained only on cultivated pastures located on muck-mineral soils. At present, Lolium perenne occurs on polders in higher amounts at the road side-spaces. Left pastures arc dominated by Juncus effusus, Deschampsia caespitosa, Cirsium arvense and Holcus lanatus.
