The diversity of synanthropic flora observed in archaeobotanical data increases over time, which is a result of several interrelated processes, taking place between the Neolithic and the Modern Period, mainly: (I) technological progress in agriculture and increasing range of crops cultivated; (II) increasing complexity of cultural landscapes; (III) immigration of alien plants. Our aim was to gain a better insight into the basic trends of archaeophytic migrations in central Europe from the Neolithic to the Medieval Period. We summarised data on macroremains from the Archaeobotanical Database of the Czech Republic, as well as data from other European countries published in international journals and monographs. In some cases we were able to identify groups of species with characteristic migration directions (e.g., Adonis aestivalis and Asperula arvensis came from the west, Fumaria officinalis and Silene latifolia from the east). Still, we need to further test these preliminary results using more robust data. Analysis of the weed seeds accompanying ancient crop remains is generally used for the reconstruction of ancient crop cultivation practices. However, we demonstrate here that the migrations of diagnostic species followed various patterns, which differed between territories. We need to keep in mind that although the presence of a species is conditioned by the existence of suitable biotopes, there are still other important factors (like propagule pressure and competition).
