Seventeen years of phytosociological observations (1977-1993) of cereal cultures in the same complex of fields in the Miechów Upland were used for this study. The region is characterised by the most intensive agriculture in the Kraków area, because of very good soil (chernozems). The study concentrates mainly on rare species, considered threatened with extinction in the territory of Poland by Warcholińska (1994).
