Abstract
Ontogenetic structure of eight Thymus mongolicus coenopopulations in Southern Siberia was studied and assessment of their state was done. It was established that the studied coenopopulations had left-hand, central and bimodal spectrum types. It was shown that the optimal state of coenopopulations was achieved in true petrophytic steppes. Organism optimum and population optimum did not coincide in the steppes on a moving substrate and under the influence of grazing.
