Scale:

1:20,000,000.

Accuracy of the map:

Map was created using literature data.

Projection:

"Alber's Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Main content:

Vector map. Main distribution area is shown by polygons, while sporadic distribution is shown by points. Zone of weediness is shown by polygons.

Accuracy of classifier:

The distribution area of the species is divided into zones of main distribution, sporadic distribution, and weediness.

Mapping procedure:

Zones of distribution and weediness were allocated following an analysis of published cartographical materials and literature. Three species are included under the name Cirsium arvense (L.) Scop. s. str., according to Cherepanov (1995) and other authors (Keller et al., 1935; Maltsev, 1937; Nikitin, 1983; etc.). These species include Cirsium arvense (L.) Scop. (Cirsium arvense var. horridum Koch.), Cirsium incanum (S.G.Gmel.) Fisch. (Cirsium arvense (L.) Scop. subsp. incanum (S.G.Gmel.) Petrak ex Iljin), and Cirsium setosum (Willd.) Bess. (Cirsium arvense (L.) Scop. var. setosum (Willd.) Iljin.). They were described earlier by some authors (Grossgeim, 1949; Maevskii, 1954; etc.) as subspecies. The species map was constructed using references from the list below, materials from the herbarium of weed plants in VIR, and the database, .Information search system on flora and fauna in reservations of Russia.. In the former USSR, this weed occurs in the European region (Volga-Don, Dnepr, Moldavian, Black Sea Coast, Trans-Volga and Crimean floristic areas), in the Caucasus, in Southwestern Siberia (Upper-Tobolsk, Irtysh, and Altai floristic areas), in Southeastern Siberia (Dauria floristic area), and along river valleys in the foothills of Turkmenia. The species is distributed throughout steppe and forest-steppe zones. Northern and southern boundaries of the main distribution area match the borders of the steppe zone. The eastern border coincides with that of the steppe weed distribution area defined in "Flora of Siberia. (Krasnoborov, 1997). In the southwest, the weed is distributed in all of the Caucasus (Grossgeim, 1949; Karyagin, 1961; Takhtadzhyan & Fedorov, 1972; Cherepanov, 1995). This species has supplanted Cirsium setosum in crops in the southern, former USSR. It is one of the main weeds of fields and meadows in Crimea, Northern Caucasus, Transcaucasia, Lower Volga basin, and Western Kazakhstan (Maltsev, 1937). The plant exhibits increased weediness on arable lands within the main distribution area in steppes of the European region and in Crimea (Nikitin, 1983).
