1:20 000 000Accuracy of map:
Map was created based on materials of maps of natural scale 1:5 000 000 - 1:80 000 000 and on literature data.Projection:
"Alber's Equal Area Conic" USSR, 9, 1001, 7, 100, 0, 44, 68, 0, 0Basic 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.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 base map used in distribution area is from Hulten & Fries (1986). The limits of the zone of harmfulness was determined according to Nikitin (1983) and Melnichuk & Kovalivska (1972) and was then adjusted according to the sources listed below as well as by the limits of the Arable Land Map (Koroljeva et al., 2003). 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.Reference citations:
