A taxonomic composition, a phytocoenotic structure and landscape-spatial organization of the coniferetum’s plantations had been analyzed. The changes of these indices were shown in retrospective review. Results. The concept of reconstruction which foresees the creation of new collections of generic complexes Tsuga, Cedrus, Ephedra, Thujopsis, preservation of the modern landscape-spatial organization of Pinaceae, Taxodiaceae, Ginkgoaceae, Cupressaceae collections, and their significant enrichment had been proposed. The main and additional assortment of plants was selected. It contained 180 taxa, 88 species and 92 cultivars (forms), 18 genera of 8 families. Conclusions.
