For 10 alien species, penetration into new areas was noted, among them Arctium minus (Hill) Bernh, Galinsoga parviflora Cav. and Lepidium ruderale L., which are invasive species in the Republic of Altai. Features of the settlement in the republic of Amaranthus blitum L., Carduus acanthoides L., Portulaca oleracea L., Parthenocissus quinquefolia (L.) Planch., Reynoutria japonica Houtt., Rudbeckia laciniata L., Rumex obtusifolius L., Thladiantha dubia Bunge allow them to be classified as potentially invasive species in the region. Most of the species discussed are xenophytes, accidentally introduced species.
