Zróżnicowanie zbiorowisk łąkowych klasy Molinio-Arrhenatheretea w krajobrazie rolniczym zachodniej części Pojezierza Drawskiego

The objects of research were 55 mid-field meadows of an up to 5 ha area, the characteristics of which were biotope conditions and the method of exploitation. The area is localized in the western part of Drawskie Lakeland. The field research was carried out in the years 1995–1999. In this period 150 phytosociological relevés were made using the Braun-Blanquet method. Collective soil samples were taken from the research area, in which the mechanical composition and the values of pH in H2O and1MKClwere determined.Within the studied meadows 11 plant communities from Molinio-Arrhenatheretea class were distinguished, of which nine were in the rank of associations: Filipendulo-Geranietum, Epilobio-Juncetum effusi, Scirpetum sylvatici, Angelico-Cirsietum oleracei, Alopecuretum pratensis, Holcetum lanati, Arrhenatheretum elatioris, Viscario-Festucetum rubrae, Ranunculo-Agropyretum repentis; and two as communities Deschampsia caespitosa and Poa pratensis-Festuca rubra.
