The article considers the results of the study of degraded bunchgrass steppes state in the Southern Kulunda area (2013-2018). It points out stages of the grassland degradation and estimates changes in the following: species composition, vertical and horizontal grass stand structure, supply of the aboveground phytomass as a result of pasture load growth.
