Basic trends of dynamics of vegetation restoration on multiple-aged terraces of the tailings storage dam of Tyrnyauz plant were revealed by using the data of fifty-year geobotanical studies within Bylym arid basin. Steppe meadow vegetation is restored faster (20 years up to the formation stage of natural phytocenoses) on upper newly built terraces. Self-overgrowing of long-standing terraces at the foot of the dam is slower (50 years). On the contrary, soil formation is more intense on lower terraces. At present phytocenogenesis can’t be considered accomplished on the dam of the tailings storage. Formation of subalpine steppe meadows on dark-humus soils is predicted on the dam area against the background of low anthropogenic load.
