Condition of introduced populations of some rare species in a typical artificial steppe in the Donetsk Botanical Garden

The paper is an assessment of the current state of the introduced populations of model species of the rare flora fraction of Donbass in conditions of artificial true steppe in Donetsk Botanical Garden. The assessment of introduction success of these species, taking into account the indicators of population parameters, has proven good prospects of using natural models for the conservation and reproduction of the rare plant gene pool due to the formation of a favorable growing environment. The populations of these phytocomponents retain the ability to maintain a stable density without any need for additional sowing seeds or planting material. They are definitive systems capable of self-sustained viability.
