The article discusses the flora railway embankments of the station Dema related to Kuibyshev Railway. Railway embankments are active ways straddling immigrations of alien plant species. On these types of landscapes are formed anthropogenically transformed floristic complexes, in addition involving a large number of adventive species. Studied in 2013-2014 flora mounds station Dema includes 217 species, of which 84 adventive species. The average number of species in the family is equal to 5.9. Ten leading families flora railways station - Asteraceae, Poaceae, Fabaceae, С.А. Хусаинова, Э.С. Сейдалиева, А.Ф. Хусаинов, Л.М.

Абрамова АНАЛИЗ АДВЕНТИВНОЙ ФЛОРЫ СТАНЦИИ ДЕМА (БАШКИРСКОЕ ОТДЕЛЕНИЕ... Brassicaceae, Chenopodiaceae, Lamiaceae, Rosaceae, Caryophyllaceae, Polygonaceae, Scrophulariaceae. The largest genera - Artemisia (6 species), Rumex (5 species), Poa (5 species), Centaurea (4 species). The time and manner of introduction, the degree of naturalization and florogenetic spectrum of flora were analized. Participation of invasive species in the flora is 38.6%, which determines the degree of its adventization. Among adventive species is high enough role neophytes (25.3%). In the flora of the study area for the new account the Bashkortostan Republic species and habitats - Ambrosia trifida, Cyclachaena xanthiifolia, Oenothera oakesiana, Oenothera biennis, Phalacroloma strigosum, Senecio viscosus, Eragrostis minor, Eragrostis pilosa.
