Abstract
Evaluation of state of 22 cenopopulations of Hedysarum theinum situated in the sub-alpine and alpine vegetation belts in Kazakhstan and the Republic of Altay was made according to the set of traits. It was revealed that the most favorable conditions for this species are those of the sub-alpine belt (12 CP), where the sums of scores for organism and population features vary from high to medium values. The pessimal state, which is characterized by the smallest values of the majority of parameters of the species, was revealed in the alpine vegetation belt at the altitude of about 2000 m above the sea level in the Rudniy Altay (Kazakhstan) and in scrub communities at the joint of the alpine and subalpine belts at the edge of the range of H. theinum in Russian Altay. The reactive-tolerant type of the population strategy of H. theinum was revealed.
