1:20 000 000Accuracy of the map:
It is created on materials of 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.Main content:
Vector map. Area is shown by polygons (main distribution) and by dots (sporadic distribution). Zone of weediness is shown by polygons.Accuracy of the classifier:
The species distribution area is divided into zones of main distribution, sporadic distribution, and weediness area. The zone of weediness is allocated inside the main area in zone of mixed fir and broad-leaved forests in western areas of flax growing, where it litters to 18% of fields (Shlyakova, 1982).Procedure of map drawing:
Zones of distribution and weediness are allocated by results of the analysis of the open-published cartographical materials and literature. The data of Krylov et al. (1949) serves as the basis for the map. Distribution of the species in the Caucasus has been updated after data of Grossgeim (1949), distribution in Siberia - after data of Krasnoborov (1997), distribution in the Far East - after data of Kharkevich (ed., 1992). It has been supplemented with the data of Tolmachev (1977), VIR Herbarium of weed plants, and Data base "Information search system on flora and fauna in reservations of Russia" (Petrosyan et al., 2003). Specifications are brought after references from the below list. The zone of weediness is allocated inside the main area in zone of mixed fir and broad-leaved forests in western areas of flax growing, where it litters to 18% of fields (Shlyakova, 1982).Sources of data:
