Date of creation:

1:20 000 000.Accuracy of the map:
It is created on materials of maps of natural scale 1:80 000 - 1:5 000 000 and on literature data.Projection:
"Alber's Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.Basic content:
Vector map. Area of distribution is shown by polygon (main distribution) and by dots (sporadic distribution). Zone of weediness is shown by polygon.Accuracy of the classifier:
The weed area is divided into zones of main distribution, sporadic distribution, and weediness. The zone of its weediness is shown, established by 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), i.e.; where the occurrence of this species exceeded 50% with its abundance (projective cover) more than 15%.Method of map production:
Area and zone of weediness are established according to the analysis of the open published maps and literature. A map compiled by Hulten E. & Fries M. (1986) is taken as a prototype. The weed area in the Caucasus is supported by the map published by A.A.Grossgeim (1950). The original area has been supplemented by dots at the area border (VIR Herbarium; Grossgeim, 1950). Sporadic distribution is given after VIR Herbarium, after a map compiled by Kharkevich (1988) and according to the literature data (Maevskii, 1954; Grigor.evskaya, 2003; Tsvelev, 2000; Shmidt, 2005; Fedchenko, 1931; Shishkin, 1957; Tikhomirov, 1986; Tolmachev, 1976). The zone of Mignonette weediness is not allocated, as there are no literature data on its high weediness; this ruderal plant is common at field margins, meeting frequently but not abundantly (Nikitin, 1983); abundance 2 points is reported on perennial grasses in Non-Black Earth Region (Korovina, 1982).Reference citations:
