Archaeophytes are alien plants introduced to the Czech Republic before the year 1500.
Their occurrence is strongly connected with agricultural production. The aim of this study was to
assess the occurrence of archaeophytes in arable fields in the Czech Republic in terms of applied
management systems (conventional and organic farming), crops (winter cereals, spring cereals,
wide-row crops) and environmental site conditions at different altitudes. In 2006–2018, a
phytocoenological survey was conducted in selected farms across the Czech Republic. Totally,
180 weed species were found, of which 48.89% were considered as archaeophytes (88 species).
In view of the invasive status, 5 archaeophytes were considered as invasive, the other 83 species
were regarded as naturalized. The net effects of all variables studied on the occurrence of
archaeophytes were statistically significant. The majority of the variation was explained by
altitude, followed by crop and type of farming. Incidence of archaeophytes increases with an
increasing altitude and is also related to their affinity with environmental factors. The highest
occurrence of archaeophytes was found in cereals, some species, however, occur more frequently
in wide row crops. The higher occurrence of archaeophytes was observed in organically managed
fields.
