The flora of Omsk Region remains insufficiently and unevenly studied. This is confirmed by numerous findings made during floristic research, which determines the relevance of continuing flora inventory work. The article presents the results of studies of the vascular plant flora of the region for the period 2013-2024. The work was carried out within the framework of the “Flora of Asiatic Russia 2.0” project and is based on field data and verified observations from the iNaturalist platform. For the first time in the region, 28 species and 5 hybrids have been identified, of which 12 species and 4 hybrids are native, while 16 species and 1 hybrid are adventive. Among adventive species, ergasiophygophytes (11 species) predominate, while by degree of naturalization, epecophytes (6 species), ephemerophytes (4 species), colonophytes and ephemerophyte-epecophytes (3 species each) are distinguished. Additional studies are required on the distribution of Sorbus aucuparia L. and Leucanthemum ircutianum DC. in the region. Widely cultivated species ( Cucurbita maxima Duchesne, C. pepo L., Solanum lycopersicum L., S. tuberosum L.) occasionally become wild and persist for a short time near cultivation sites (garden plots, individual residential areas) and landfills. Four rare species have been proposed for inclusion in the Red Book of Omsk Region: Dianthus krylovianus Juz., Astragalus lagobromus Knjaz. & Kulikov, Bupleurum aureum Fisch. and Eremogone koriniana (Fisch. ex Fenzl) Ikonn . The study results significantly expand the known vascular plants flora of Omsk Region, this is of great importance for biodiversity conservation and planning of environmental protection measures.
