The vegetation cover of arid ecosystems in the territory of uranium mines of NAC Kazatomprom JSC and adjacent territories (Ashchykol Depression, Betpak-Dala) is affected by both anthropogenic and technogenic factors. Anthropogenic, technogenic impact on vegetation and soil cover led to a significant reduction in species diversity and an increase in the proportion of weeds. The activity indicator of species is an important parameter of environmental monitoring and the effectiveness of recultivation. Some of the promising objects of recultivation are Haloxylon aphyllum, Calligonum aphyllum, which are widespread in the study area and tolerate not only anthropogenic but also technogenic impacts.
