Abstract
The purpose of the paper is the floristic analysis of artificial tree and shrub plantings and naturally formed living ground cover of the Arboretum of V. N. Sukachev Institute of Forest, Siberian Branch, Russian Academy of Sciences, Krasnoyarsk. A flora inventory was carried out, the higher plants species composition was determined. As a result, a summary of the flora was compiled. It was found out that the dendroflora includes 136 species (excluding varieties and forms, as well as species growing in the seed department and not included in the Arboretum exposition) from 61 genera, 29 families, 2 classes, 2 departments. The flora of the living ground cover consists of 53 species, 43 genera, 24 families, 3 classes, and 2 departments. The taxonomic, chorological, zonal, biomorphological, ecological flora structure features were determined based on the analysis of floristic data. The peculiarities of vegetation cover species composition are marked on the basis of the comprehensive flora analysis. The authors made the conclusion that mesophytes of the nemoral, light coniferous and forest-steppe belt-zone groups with the Eurasian and East Asian ranges predominate in the flora of the Arboretum of V. N. Sukachev Institute of Forest, Siberian Branch, Russian Academy of Sciences, Krasnoyarsk. The most part of species has the life forms phanerophyte and hemicryptophyte.
