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 weed is considered a serious pest. Points represent locations where sporadic occurrence has been reported. The zones of harmfulness were established according to criteria of occurrence (% of fields where this species is found) and abundance (expressed as projective cover of this species in the field [in % to the field area]) where the occurrence of this species exceeded 20% with its abundance (projective cover) more than 15% (Tanskii et al., 1998).

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 area of distribution is based on the map from Hulten & Fries (1986). The areas of harmfulness are established according to Korovina (1982) and adjusted according to the limits of the arable land map (Koroljeva et al., 2003). In addition to the data of Hulten & Fries (1986), the sites of sporadic distribution in the Caucasus were determined according to Grossgeim (1945); in the Far East according to Kharkevich (1988); in Siberia according to Krasnoborov (1992) and Dorogostaiskaya (1972); in the north and north-east of the European part of the Former Soviet Union according to Tolmachev (1976), Kostina (2001) and Dorogostaiskaya (1972). In the territory of Siberia part of the sites of sporadic distribution determined according to Krasnoborov (1992) and Hulten & Fries (1986) were included into the main area. 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.
