Abstract
The assessment of 16 cenopopulations of Hedysarum alpinum including individual and population level was conducted on the territory near Lake Baikal. Floodplain meadows proved to be the most favorable habitats for the studied species. Cenopopulations from the permafrost zone and cenopopulations under human impact were characterized by pessimal state with the lowest values of the species’ parameters. The ability of H. alpinum to grow in unfavorable conditions by means of decreasing individual parameters and population characteristics has the adaptive significance. This ability determines the main integral property of the species which is tolerance.
