It is our priority to conduct environmental monitoring, protect rare plant species and conduct studies to assess the state of populations of rare and endangered plants using coenopopulation approaches is a priority, along with the conservation of plant communities with participation of rare species. The aim of our work was to study the ecological and phytocenotic state of rare Xylosalsola chiwensis and Scorzonera bungei coenotic populations in Ustyurt. These species are listed in the Red Data Book of the Republic of Uzbekistan. We provide the characteristics of plant communities with cenopopulations of the studied species. The ontogenetic structure of these species has been studied. The results showed that in the ecological and cenotic conditions of Ustyurt, the studied coenopopulations are normal, but incomplete. The basic ontogenetic spectrum is centered, with a peak of the middle-aged generative plants. The spectra of specific cenopopulations are centered and left-sided due to the ecological habitat conditions and weather fluctuations. With the development of distant pastures and the planning of linear infrastructures, these species must be protected. The results of this study will be used in the next editions of the Red Data Book of the Republic of Uzbekistan.
