Species composition of phytocoenoses of overburden dumps at Chernogorsky quarry has been investigated. Systematic, chorological, environmental and biomorphological analysis of flora has been carried out. It has been found that the quarry flora includes 47 species of higher vascular plants that are related to 35 genera and 16 families. 97.9 % are metasperms. Asteraceae and Poaceae are the largest families. Species with Holarctic areas prevail in the chorological structure (36.2 %). In terms of soil moisture all species can be subdivided into 3 groups: mesophytes (40.4 %), mesoxerophytes (36.2 %) and xerophytes (23.4 %). The leading role in the researched flora belongs to herbaceous polycarpous plants (57.4 %), which is characteristic of all the boreal region flora. 1 species listed in the Red Books of the Republic of Khakassia was discovered in the overburden dumps (Nitraria sibirica Pallas) and 6 species which have been noted for the first time for the flora of Khakassia.
