Protection and renewal of species variety is an important problem nowadays. Genetic information accumulated in the course of evolution is unique and vanishing of any species or population leads to their irreversible losses. It is especially urgent for the rare, relict and endemic species of plants which mainly have a small number of populations and limited natural habitats. Disappearance of any population results in the irretrievable loss of a part of species’ features. The investigation of population is considered to be the base to fill the content of the Red Lists, besides the investigations help to determine the level of threat of a species and develop measures as to the protection and renewal of population.
The Ukrainian Carpathians numbers 20 species registered in the basic international Red Lists. The article contains information concerning 6 rare herbaceous species in the Ukrainian Carpathians, namely: Achillea schurii, Heracleum carpaticum, Larix polonica, Pulmonaria filarszkyana, Silene dubia, Silene zawadskii which has been accumulated and supplemented.
