The article presents results of monitoring observations on the state of introduced populations of the rare steppe species Paeonia tenuifolia L., based on the dynamic analysis of density, age and vitality composition of populations, as well as the study of the spatial distribution of individuals. Taking into account population characteristics, introduction success of the species in conditions of the artificial steppe in Donetsk Botanical Garden is shown. It was established that in natural models of the real steppe, favorable conditions were formed for functioning of self-maintenance process in the species populations, which is a necessary pre-requisite for successful, long-term conservation of this species and rare phytogenic pool as a whole. The introduction success of P. tenuifolia was assessed in 7 points out of 8, indicative of good prospects for preserving this species ex situ.
