Authors:

Object specialist - S.Yu. Larina, GIS-specialist - I.A. Budrevskaya.

Data of creation:

15.03.2004.

Scale:

1:20 000 000.

Accuracy of map:

Map was created based on materials of maps of natural scale 1:5 000 000 - 1:100 000 000.

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 the weed is considered a serious pest. Points represent locations where sporadic occurrence has been reported. Within the weed distribution area the zones of harmfulness were determined according to criteria of occurrence (the % of fields where this species is found) as well as abundance (expressed as a projective cover of this species in the field (in % of the field area))(Tanskii et al., 1998). The zones of harmfulness represent an occurrence of the species greater than 20% and a abundance (projective cover) greater 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 area of distribution is based on the maps from Hulten & Fries (1986) and Volkov (1935). The eastern part of the distribution area is extended further to the east of the European part according to Volkov (1935). The areas of harmfulness are established according to Nikitin (1983) and adjusted according to the map of arable lands (Koroljeva et al., 2003). In addition to the data of Hulten & Fries (1986), the sites of sporadic distribution are determined according to Kharkevich (1988) in the Far East, Malyshev & Peshkova (1994) and Stepanov (1990) in Siberia, Dorogstaiskaya (1972) and Tolmachaev (1976) in the northern regions of the European part of Russia and Siberia, as well as Grossgeim (1950) in Caucasus. 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.
