The State of Coenopopulations of Crambe Edentula Fisch. & C.A. Mey. Ex Korsh in the Conditions of Karakalpak Ustyurt

Abstract

The state of 4 cenopopulations of a rare species Crambe edentula for the Republic of Uzbekistan has been studied. The ontogenetic structure of the species is associated with the ecological-cenotic conditions of growth and fluctuations in weather conditions. C. edentula can be considered a threatened species because all studied cenopopulations are incomplete, due to the absence of a fraction of young individuals. This is evidenced by the types of cenopopulations, which are assessed as young, maturing, transitional, and mature. The investigated species is recommended for inclusion in the Red Book of the Republic of Uzbekistan.
