Zbiorowiska seminaturalne z rzędu Arrhenatheretalia klasy Molinio-Arrhenatheretea występujące na terenie byłej Akademii Rolniczej w Szczecinie przy ulicach J. Słowackiego i Papieża Pawła VI
Abstract
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.
