Abstract

Records of alien species of vascular plants in the Yamal-Nenets autonomous area (Russia).

Abstract

The article provides information on floristic findings made in 2017 in the territory of the Novy Uren- goy urban district (Russia, Yamal-Nenets Autonomous Area). The Yamal-Nenets Autonomous Area is located in the north of Western Siberia. Novy Urengoy is located in the continental part of the region, in the natural zones of the forest-tundra and taiga (subzones of the northern and middle taiga). Novy Urengoy is the largest city and industrial center of the Yamal-Nenets Autonomous Area. The local flora is enriched with alien species under the influence of gas and oil production, roads construction, industrial enterprises, and settlements development. So far, little attention has been paid to the study of the migration of such plants in the Russian Arctic and Subarctic regions. Since alien species, on the one hand, can theoretically pose a threat to local ecosystems, and, on the other, enrich the flora of the region, they need to be monitored in the High North. In the course of field studies, 16 species of vascular plants were found (Agropyron pectinatum, Artemisia dracunculus, Brassica nigra, Camelina microcarpa, Erysimum canescens, Lolium remotum, Malva pusilla, Panicum miliaceum, Pedicularis sibirica, Ranunculus polyanthemos, Senecio jacobaea, Si- napis alba, Sisymbrium volgense, Sonchus asper, Veronica incana, V. spicata), which were not previously reported for the Yamal-Nenets Autonomous Area and 6 alien species rarely found in the region (Achillea nobilis, Artemisia absinthium, A. sieversiana, Astragalus danicus, Chenopodium karoi, Phacelia tanacetifolia, Trifolium montanum).
