Abstract
The analysis of Trans-Urals (the Bashkortostan Republic) steppes has been carried out using 428 relevйs. Groups of species indicating position of plant communities on moisture and stoniness gradients were defined. We used ANOVA-based technique of definition of indicator species groups. The role of indicator species in diagnostic combinations of Trans-Urals steppe syntaxa was determined.
