Abstract
The article shows the importance of specially protected areas for preserving the gene pool of rare and useful plants in Siberia on the example of the "Relic oaks" state landscape reserve. The landscape reserve is located on the territory of Eastern Siberia (Russia), on the two large floristic areas of Holarctic: Circumboreal and East-Asian. During the study, 696 species of higher vascular plants have been identified in the territory of the landscape reserve. The prevailing families are following: Asteraceae, Poaceae, Ranunculaceae, Rosaceae, Cyperaceae, Fabaceae, Caryophyllaceae, Brassicaceae, Apiaceae, and Scrophulariaceae. In the territory of landscape reserve, 4 floral complexes were identified: alpine, forest, steppe and meadow-alluvial, as well as 10 chorological groups. The feature of the flora was prevalence of forest and steppe plant species with the East Asian type of habitat. By the number of species, herbaceous plants in the landscape reserve dominate over arboreal plants, and shrubs have the largest share among arboreal plants. The spectrum of life forms of plants shows the climatic conditions of the territory at the border of large floral areas and zones of vegetation. On the studied territory, there are 171 species of higher vascular plants (24.5% of the total flora composition in the landscape reserve), are rare and protected in various regions of Siberia.
