Conservation of Eremurus spectabilis M.Bieb. in situ and ex situ in the Donetsk People’s Republic

The current state of natural and introduced populations of Eremurus spectabilis М. Bieb has been investigated by studying their density, age composition, spatial distribution of individuals in natural habitats and within the structure of experimental steppe in the conditions of Donbass. The values of integral indicators reflecting dynamic processes are given, namely indices of generativity, replacement renewal and aging. Cenopopulations are most stable in conditions of slope habitats in sparse petrophyte-steppe and steppe phytocenoses. A promising way to preserve E. spectabilis is its cultivation.
