The problems concerning the restoration of natural populations are discussed in the article. A phased study of the processes of reconstruction of populations was carried out using six rare Siberian species: Allium eduardi Stearn ex Airy Shaw (Amaryllidaceae), Brachanthemum krylovii Sergievsk. (Asteraceae), Hedysarum theinum Krasnob. (Fabaceae), Viola taynensis T. Elisafenko et Ovczinnikova, V. dactyloides Schult., V. ingolensis T. Elisafenko and hybrid Viola x incissecta Vl.V. Nikit. (Violaceae). The conclusions are made regarding the success of restoration work for populations of each species based on the results obtained in the reconstruction process. Th e problems of choosing a place for reconstruction and genotypic matching of the donor and recipient are considered. Th e agricultural activities to reduce competition must be organized in the early years. It was noted that the temp of development and morphological characteristics of reintroducents correspond to the development of plants of natural populations for most species and this depends on the biological characteristics of a particular species. Th e possibility of reconstructing Hedysarum theinum, Viola dactyloides, V. ingolensis and Viola x incissecta in existing cenoses has been identifi ed. Th e search for new reconstruction sites for V. taynensis and the use of translocation and repatriation (in vitro) for Brachanthemum krylovii are necessary.
