Abstract
Cirsium helenioides (L.) Hill. (Asteraceae) is the long-lived short-rhizome herbaceosus polycarpic plant, one of the dominant plant in tall-herbal meadows in Salair Ridge. The ontogenetic structure and density of 10 coenopopulations of C. helenioides in the tall-herbal meadows in Salair Ridge was studied. The coenopopulations is normal type, young, mature or aging, full-member and not full-member. The maximum coenopopulations density for young and the minimum density for aging coenopopulations is registered. The seedage of C. helenioides in tall-herbal meadows is irregular. It is shown that C. helenioides in this type of meadows is the temporary successional dominant.
