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 zone of weediness was allocated according to criteria of occurrence (% of fields where this species is found) and abundance (expressed as projective cover of this species in the field) (Tanskii et al., 1998), i.e., where the occurrence of this species exceeded 50% with its abundance (projective cover) being more 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 map from Hulten & Fries (1986) was used as a prototype and was adjusted according to the following sources: the area border on Kola Peninsula was shifted slightly eastward according to Poyarkova (1966); in Arkhangel.sk Region it is shifted slightly northward according to Hulten & Fries (1986) and Tolmachev A.I. (1977); the Crimea was included into the area according to the data on the species weediness by Vasil.ev (1929). Sporadic distribution was determined according to Hulten & Fries (1986), Poyarkova (1966), Tolmachev (1977), Dorogostaiskaya (1972), Malyshev & Peshkova (1976), and the herbarium of Moscow State University. The zone of weediness was outlined according to literature data and the map of arable lands (Koroljeva et al., 2003). Criterion used was the indication that the weed has an abundance to 3 points in perennial grasses in Non-Chernozem Zone (Shlyakova, 1982), as a weed plant in Brest and Gomel Regions in grain crops (Kozlovskaya & Simonovich, 1966), and having an occurrence of 78% in orchards of Crimea (Vasil.ev, 1929). 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.
