    Zbiorowiska seminaturalne klasy Molinio-Arrhenatheretea (z rzędów Plantaginetalia majoris i Trifolio fragiferae- -Agrostietalia stoloniferae) występujące na terenie byłej Akademii Rolniczej w Szczecinie przy ulicach J. Słowackiego i Papieża Pawła VI

    The order of Plantaginetalia majoris represents 13 patches of vegetation in the examined area. They were classified into the complex of Lolio-Polygonetum arenastri. These phytocentoses occur along roads, paths and pavements and on trodden surfaces. They settle mainly in compact soils of alkaline reaction. In the complex two species Lolium perenne var. humile and Plantago major var. typica dominate. In a part of patches a facial form is reached by: Trifolium repens, Achillea millefolium and Ficaria verna. Within the order of Trifolio fragiferae- -Agrostietalia stoloniferae a community of Potentilla reptans was distinguished. The patches of this phytocenosis are mainly found on warm and exposed to the sun slopes, on thinned out lawns, along paths and roads. The dominating species in the complex is Potentilla reptans (S=V, D=2324), it is accompanied by numerous species of Molinio-Arrhenatheretea class (25 taxa). The largest reciprocal similarity is shown by ruderal communities formed in dry and warm habitats, and a slightly smaller similarity is observed in the case of meadow and bush complexes. The least similar in respect of floristic composition and phytocociological stability of species are complexes of Echio-Melilotetum i Onopordetum acanthii as compared to the communities of the forest variant of Urtico-Aegopodietum podagrariae and Lolio- Polygonetum arenastri.

    Phytocenoses of Arrhenatheretalia order are representative in the investigated area for 46 vegetation patches classified into the complex of Arrhenatheretum elatioris and into the community of Poa pratensis-Festuca rubra. Arrhenatheretum elatioris complex is most frequently found on warm and dry small slopes situated in different places of the studied area, on moderately compact soils of alkaline reaction. The most species in the complex are representative for Molinio-Arrhenatheretea class (32 taxa), and some of them, Poa pratensis and Festuca rubra, reach a facial form in some vegetation patches. The structure of Arrhenatheretum elatioris complex has a character of a temporary community referring to phytocenoses of Artemisietea vulgaris class, which is represented by 30 taxa, of which Urtica dioica and Chelidonium majus reach a rank of facies in a part of patches. The vegetation patches in which Arrhenatherum elatius occurs were classified into Poa pratensis-Festuca rubra community. It also settles down on exposed to the sun and dry slopes of small hills, but it is also found on flat sheltered areas. Like in the previous complex, in the structure of this community the species characteristic of Molinio-Arrhenatheretea (27 taxa) and Artemisietea vulgaris (24 taxa) class are dominating. The structure of both seminatural communities found mainly in meadow habitats has a temporary character in the investigated area. A considerable number of species from Molinio-Arrhenatheretea class is a result of the activity of human being who introduced into the investigated area organic soils taken from meadows, containing reproductive organs of these species.
