Rhaponticun carthamoides (Willd.) Iljin is a rare medicinal plant listed in the Red List of the Russian Federation. Spatial patterns of its reserves were studied for the monitoring and protection of wild populations at the Kuznetsk Alatau. The dependence of population abundance on environmental factors was revealed by geobotanical profiles. We derived the equation of nonlinear regression for rapid method of determining the weight of subsurface parts by counting the number of shoots. To assess rapidly and monitor the natural reserves we developed a mathematical model describing the abundance of R. carthamoides and its habitat altitude.
Key words: Rhaponticun carthamoides, conservation, environmental factors, abundance
