1:20 000 000.Accuracy of map:
Map was created based on materials of maps of natural scale 1:15 000 000-1:100 000 000 and information taken from open-published literature.Projection:
"Alber's Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.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.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 of Hulten & Fries (1986) was used as a base and adjustments were made according to the following sources: Po.arkona (1956), Tolmachev (1974), Kharkevich (1992). The zone of harmfulness was determined according to Nikitin (1983). 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:
