The article is devoted to the assessment of the state of the ontogenetic structure of the rare species Crambe edentula Fisch. & C.A. Mey. ex Korsh., growing in the Karakalpak part of Ustyurt. The study showed that in the ecological-cenotic conditions of Ustyurt, the studied cenopopulations are normal, mostly incomplete. The characteristic ontogenetic spectrum for C. edentula is centered due to an increase in the life span of individuals in a mature generative state and poor seed renewal. Ontogenetic spectra of cenopopulations do not coincide with the characteristic one. The spectra of specific cenopopulations are left-sided and right-sided, which is associated with ecological habitat conditions and fluctuations in weather conditions.
Keywords: Ustyurt plateau, infrastructure development, endemics, rare plant species, ontogenetic structure, age and efficiency of cenopopulations.
