Abstract
The paper presents the first results of a study of ergasiophygophytes in the Altai Territory. Ergasiophygophytes include alien species that are or were cultivated in this area, have “escaped” from cultivation, and are capable of colonizing the anthropogenically disturbed habitats and penetrating natural communities.
As a result of an inventory of alien flora in the Altai Territory, 155 vascular plant species from 46 families and 115 genera can currently be classified as ergasiophygophytes. In terms of the species number, the most numerous are the families Fabaceae (19), Rosaceae (18), Poaceae (11), and Brassicaceae (10). Half of the families (23) and three-quarters of the genera (87) are represented by only one species. Most ergasiophygophytes in the studied area are perennials, phanerophytes being the most numerous. A chorological analysis using R.V. Kamelin's classification of the flora of the Earth has shown that the species with boreal-ancient Mediterranean, ancient Mediterranean, and boreal types of distribution area are predominant among ergasiophygophytes. Most of these species originate from Eurasian floras.
