Abstract. The purpose of the studies was to identify relatively preserved steppe areas and to make an inventory of the systematic structure of the flora for the scientific substantiation of measures to protect the biodiversity of the Kuznetsk Basin steppes. The territory of the Kemerovo region was studied in 2001–2020 by route methods, as well as by the method of partial floras. The steppe flora in the Kuznetsk Basin includes 48 families, 223 genera, and 457 species. It is based on angiosperms; dicotyledons account for 82% of the total number of species. In the family-species spectrum of the Kuznetsk Basin steppe flora, the 10 leading families account for 69.61%; the share of homogeneous families exceeds 56%. The set of leading families is generally typical for most boreal floras, but it is distinguished by a reduced proportion of the Cyperaceae (13 species) and Scrophulariaceae (16 species) families. The main taxonomic indicators of the steppe flora of the Kemerovo region emphasize its specific features, including those reflecting its migratory origin. During the observation period, the composition of the steppe flora and number of species decreased; some of them can be considered extinct in the territory of the Kemerovo region, since there are no single point of location and no herbarium confirmation. Restoration of the steppes presupposes the preservation of the gene pool of steppe species, their diversity and biocenotic unity. The existing system of specially protected natural areas does not cover all types of habitats. A huge part of the species of steppe communities growing outside specially protected natural areas are confined to the most anthropogenically developed plain areas of the Kemerovo region. The problem can be solved by the organization of additional specially protected areas. This will allow preserving the habitats of rare steppe species and stabilizing the plant diversity of Kuznetsk Basin in general.
