The paper presents a floristic analysis of the nature monument «Verkhnezaglyadinsky Kinelsky Yar». The taxonomic analysis showed a growth of 107 species of vascular plants from 83 genera from 29 families on this territory. The analysis of life forms according to I.G. Serebryakov showed a predominance of herbaceous perennials, namely short-rooted (24 species) and rod-rooted (19 species) grasses. According to Raunkier’s classification, hemicryptophytes (77 species) are the predominant life form. The ecological and geographical analysis showed that the forest-steppe (40 species) and mountain-steppe (20 species) groups were represented by the largest number of species. According to the method of N.M. Matveev a complete ecomorphic analysis was carried out. The chorological analysis showed a predominance of plants with the Eurasian type of habitat in the flora (47 species). Plant species with endemic habitats (18 species), as well as relic plants (5 species) have been noted, which raises this natural monument to a considerable height. The flora of the Verkhnezaglyadinsky Kinelsky Yar includes 3 species from the Red Book of the Russian Federation and 7 species from the Red Book of the Orenburg Region. The studied natural monument is well described from a geological point of view, and our work has expanded its floristic study. In conditions of anthropogenic load caused by the proximity of highways and settlements, it is necessary to organize constant monitoring of the state of the nature monument «Verkhnezaglyadinsky Kinelsky Yar».
