Basic contents:

Vector map. Area of species distribution is shown by polygons, and sporadic distribution by points. Zones of weediness are shown by polygons.

Accuracy of classifier:

The weed area is subdivided into two zones, one representing species distribution, and the second where the weed is considered a serious pest. Points represent locations where sporadic occurrence has been reported. The zone of harmfulness for this species was established based on occurrence (% of the fields where this species is found) and abundance (expressed as projective cover of this species in the field (in % of field area)) (Tanskii et al. 1998). Harmfulness was determined when the occurrence exceeded 20% and its abundance was greater than 15%.

Method of map production:

Published literature was reviewed, including Atlases, monographs and papers. Occurrence data were obtained from herbarium specimens, floras, monographs and papers. The limits to the area of distribution of this species were determined according to the following sources: Hulten & Fries (1986), Grossgeim (1950), Karkevich (1988), Krylov (1931), Malyshev & Peshkova (1994). The northern limits were adjusted according to the northern limit of the forest-steppe zone (Komarov & Bush, 1939). The areas of weediness were established according to the following sources: Fomina (1962), Vasilyeva & Matsenko (1964), Plotnikov & Levchenko (1965), Koroljeva et al. (2003). The sites of sporadic distribution were determined according to Hulten & Fries (1986) and adjusted according to the following sources: In the northeast of the European part of the former Soviet Union by Tolmachaev (1976); in the north of the European part of Siberia by Gusev (1975) and Dorogostaiskaya (1972); in Udmurtia by Puzyrev (1984); in the Tver region by Malysheva (1979). In other areas of the former Soviet Union sporadic distribution was determined according to the following sources: Shults (1977), Parfenov (1985), Bosek (1986), Konechnaya & Ignatyeva (1996), Shilova et al. (1989) and Shaga (1989). Data were then compiled through scanning and geo-referencing to develop a composite vector map. The biologist, together with the GIS specialist, drew a composite weed distribution area based on compiled data.
