In the White Carpathian Mts, a mosaic of species-rich patches have developed in a regularly mown dry grassland in the area of a glassworks abandoned in the eighteenth century. Using magnetometry we detected former furnaces, workspace, waste deposit and unaffected surrounding grasslands and compared their vegetation and environmental conditions. Archaeological features, especially furnaces and waste deposits, showed a higher pH, higher soil concentrations of exchangeable phosphorus, manganese, lead and calcium, and higher productivity. Plant compositional variation was best explained by water extractable phosphorus. Because nutrient-richer patches were not moister as common elsewhere, and because species richness was only poorly accounted for by productivity, the occurrence of a species-poor ‘mesic’ vegetation on archaeological features was evidently caused by a long-lasting phosphorus oversupply, which favours a comparatively small species pool of rather recently arriving species.On the contrary, surrounding phosphorus-poorer grasslands still contain the ancient species pool whose extraordinary size determines the exceptional species richness of grasslands in the study region. Its maintenance or restoration demands a persistent phosphorus deficiency.
