On the sandy medium (loose sand and slightly loamy sand) of alkaline reaction, the following phytocoenoses: Corispermo- -Brometum tectorum, Calamagrostietum epigeji, Convolvulo arvensis-Agropyretum repentis and the community of Salix viminalis (vegetation patches situated in the lower layer) are found. The dense medium (heavy loamy sand and clay) in the lower layers of the pit is settled by patches of Poo-Tussilaginetum farfarae and the land form of Phragmitetum australis. The sandy media, but of strongly acid and acid reaction are settled by phytocoenoses of Diantho-Armerietum elongatae and Diplotaxi tenuifoliae-Agropyretum repentis associations and also by the community of Helichrysum arenarium and Hieracium pilosella. The considered objects, i.e. the pits remaining after the exploitation of aggregates, constitute a valuable natural area. A lot of plant communities occur in a small ecologically differentiated area.plUznanie autorstwa-Użycie niekomercyjne 3.0 Polskabiologiczna rekultywacjawyrobiskozbiorowiska synantropijnebiological reclamationsynantropic communitiesworkingDyscyplina::Nauki rolniczeArticle2300-5378
