Variability of morphometric features in individuals from three cenopopulations of the species Rhaponticum carthamoides (Willd.) Iljin, rare for the Altai Republic, has been studied. Insufficient precipitation in the period preceding flowering is a limiting factor for the growth and development of plants of this species. The studied cenopopulations on the Seminsky Pass and the Krasnaya Mountain are normal definitive, their individuals are characterized by a sufficiently high seed production. As a result of the moderate anthropogenic load from the fragments of rhizomes left in the soil during the harvesting of the underground part of plants, the adult generative plants become rejuvenated and the proportion of virgin individuals increases. In our opinion, intensive, uncontrolled exploitation in the collection of roots leads to a violation of the demographic structure of the cenopopulations. The recommended protection measure is the regulation of anthropogenic load in these habitats. It is necessary to further control the condition of the cenopopulations of this rare and resource species.
