A post-extraction gravel pit was subjected to technical reclamation where by the pit
was filled with fly ash and covered by a 37–150 cm thick soil layer. Subsequently, biological
remediation was applied: the area was sowed with Lolium perenne, Festuca pratensis, Dactylis
glomerata, Poa pratensis, Phleum pratense and Trifolium repens. Ten years after the
remediation treatments, 47 phytosociological relevès were taken. Two associations were
identified: the Artemisio-Tanacetum vulgaris and the Calamagrostietum epigeji. In addition, the
area was found to support the Arrhenatheretum elatioris dactylidetosum glomeratae subassociation
and a community with Elymus repens. The presence of a total of 133 taxa was
recorded. The communities were similar in their species richness which varied from 79 to 81
taxa per community. The lowest species richness (56 taxa) was found in the community with
Elymus repens. Of those species introduced during remediation, only Dactylis glomerata proved
very frequent, but occurred at small patches. Less frequent were Poa pratensis and Festuca
pratensis. The remaining species occurred only sporadically; their development during the
succession was limited, or they were eliminated altogether, by other taxa developing
spontaneously, e.g., Elymus repens.
