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. Within the weed area of Chorispora tenella the zones of its weediness were determined 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)) (Tanskii et al., 1998) where the occurrence of this species exceeded 20% with its abundance (projective cover) 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 limits to the area of distribution were determined according to the maps of Keller (1934) and Grossgeim (1950). The northern limit to the area was adjusted according to the steppe zone (Volosnova, 1986). The area of weediness was established according to Korovina (1981) and coordinated with the limits of the arable land map (Koroljeva et al, 2003). The sites of sporadic distribution of Chorispora tenella were determined according to the following sources: In the Far East by Kharkevich (1988) and Antonova (1991); in Siberia by Malyshev & Peshkova (1994) and Ebel (1997); in Udmurtia by Puzyrev (1984); in the north-east of the European part of the Former Soviet Union by Tolmachev (1976) and Lavrenko & Kustysheva (1990). In other places within the European part of the Former Soviet Union they are established according to the following sources: Borisova et al. (2001), Gusev (1975), Komendar (1978), Lyakavichyus (1982), Notov (1986), Popov (1994), Shults (1976), Shilova (1989), Volosnova (1986). 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.
