Increasing pressure on vegetation of fodder crops fringes to sharp downfall of turf cover and sometimes to full annihilation of turf cover of pasturing grounds. Stationary researches show that identical in degree of turf cover sites of different exposition differently response to pasturage the same intensity. We have been studded the correlation of phonological phases Festuca valesiaca Gaudin Nym. on the sites of eastern and western exposition. The cause of irregularity denudation of the sites is the different correlation of young and grown-up individuals of the main turfer of steppes - F.valesiaca.
