Accuracy of map:

Created based on information taken from open-published literature and maps of scale 1:5, 000,000 - 1:80,000,000.


"Alber's Equal Area Conic for the USSR" 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic content:

Vector map. Area is shown by polygon (the main distribution) and points (sporadic distribution). Zone of weediness is shown by polygon.

Accuracy of classifier:

Distribution of the species is divided into zones of the main distribution, sporadic distribution, and weediness area.

Method of map production:

Area and zones of weediness outlined according to results of the analysis of open-published cartographical materials and literature. The area of distribution is based on the map taken from E. Hulten & M. Fries (1986). Areas of distribution in the European part and in the Caucasus were finally united based on reference data (Makarova V.A., 1955; Grin.ko N.I. et al.,1987; Galushko A.I., 1980; Grossgeim A.A., 1949). The area in Western Siberia was expanded eastward according to numerous herbarium and literature records (Kushnirenko V.P., 1949; Kirshin N.K., 1977; Hulten E. & Fries M., 1986). The area in the Far East (Primorskii Territory) was drawn according to the map of Kharkevich S.S. (1992), data of Voroshilov V.N. (1966) and Korovina O.N. (1983), herbaria of BIN and VIR. The zone of weediness in the European part and in the Far East was coordinated with the map of rye crops, where the weed was reported as especially harmful (Kozlovskaya N.V., Simonovich L.G., 1966; Samersov V.F., Padenov K.P., Soroka S.V., 2000; Skorokhod V., 1951); it is coordinated with the map of arable lands in Western Georgia (Tatishvili G.S., 1955). The zone has been repeatedly reported as having a species projective covering to 30% (Bagmet L.V. & Sokolova T.D., 2003); or C. canadensis being the most harmful (Verbin A.A., 1955; Nikitin V.V., 1983; Sukhin V.S., Moiseeva T.M. & Vasyuta Z.R., 1983; Tatishvili G.S., 1955), the most widespread (Grin.ko N.I. et al., 1987; Makarova V.A., 1955), the most harmful (Orlov I., 1962), primary (Kazakevich L.I., 1951; Skorokhod V., 1951) or principal weed population (Kushnirenko V.P., 1949) in different districts.
