Date of creation:

1:20 000 000Accuracy of the map:
Map was created based on a map of natural scale 1:10 000 000 - 1:55 000 000 and on literature data.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. The zone of weediness was allocated within the main area in the forest zone (from middle taiga to broad-leaved forests) where it litters about 14% of fields (Shlyakova, 1982) with an abundance of about 2 points (Nikitin, 1983).Method of map production:
Published literature was reviewed, including Atlases, monographs and papers. Occurrence data were obtained from herbarium specimens, floras, monographs and papers. L. communis map taken from Hulten & Fries (1986) was used as a prototype. It was supplemented with the data of the following sources: Krasnoborov (1997), Tolmachev (1977), Kharkevich (1992), Petrosyan et al. (2003). Specifications were made according to references from the below list. The new northern border of the area in the European part was determined according to the data of Tolmachev (1977). 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:
