Couch grass (Agropyron repens L.) was the dominant species in 5 investigated communities with stability class 5, while its share in the community Agropyron repens + Festuca rubra was as high as 42.2%. Communities with the dominance of Agropyron repens + Deschampsia caespitosa and Agropyron repens + Avenula pubescens represent the greatest variety of their constituent species, a total of 43 vascular plant species from 15 botanical families having been recorded and 7 accompanying speciens. Due to the advantageous floristic composition and the fodder value score FVS of 6 or even higher, most analyzed communities are of considerable fodder value, although the value of the sward is reduced by taxa of low nutritive value and of low yielding potential. Semi-heliophilous plant species are dominant in that community, occupying partially dry, fresh and even moist habitats indicating acid soils with a high content of nitrogen compounds (N = 6.6). In Polish literature there is no synthetic study of a community with the dominance of true wheat grass Agropyron repens (L.) P.Beauv. that would focus on floristic composition, yield as well as natural and production value.
