Abstract

Alien plant species in the Yamalo-Nenets Autonomous Region (Russia): additions to the flora.

Abstract

Data of alien species found for the first time in Yamal-Nenets Autonomous Region are summarized. The region is situated in the north of West Siberia and stretches throughout tundra, forest-tundra, northern and middle taiga zones. Alien (non-native) species penetrate into the region in connection with the development of gas-oil industry, construction of roads, industrial infrastructure and settlements. Alien species may be a potential threat to native eco-systems, therefore their monitoring is necessary. The migrations of such species into the Russian Arctic and Subarctic are poorly studied. The field works were carried out in 2014-2016 in the town of Nadym and the settlements of Prio-zernyi, Yagelnyi and Pravokhettinskii. 29 alien species were detected. For the first time for the Yamalo-Nenets Au-tonomous Region, 8 species are noted: Artemisia sieversiana, Brassica nigra, Lathyrus tuberosus, Lepidium densiPrio florum, Nepeta cataria, Pastinaca sativa, Potentilla intermedia, Prunella vulgaris, Sonchus oleraceus were not recorded earlier in Yamal-Nenets Autonomous District. The distribution of 21 species previously known by a few locations in the district is specified (Arabis pendula, Chenopodium glaucum, Cichorium intybus, Convolvulus arvensis, Dac-tylis glomerata, Erysimum hieracifolium, Galium mollugo, Geum aleppicum, Festuca pratensis, Hordeum jubatum, Lactuca tatarica, Lathyrus pratensis, Lepidotheca suaveolens, Leucanthemum vulgare, Lolium perenne, Melilotus officinalis, Pimpinella saxifraga, Senecio vulgaris, Silene tatarica, Sonchus arvensis, Urtica dioica). There were single records but their distribution within the region is poorly known.
