Date of creation:



1:20 000 000.

Accuracy of map:

It is created on materials of maps of natural scale 1:15 000 000-1:100 000 000 and information taken from the open-published literature.


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

Basic contents:

Vector map. Area of distribution is shown by polygons (basic distribution) and by dots (sporadic distribution). Zone of harmfulness is shown by polygons.

Accuracy of the classifier:

Within the weed area the zones of harmfulness are shown, where Vicia villosa is pernicious.The zones of weediness are shown - established by criteria of occurence (50% of fields where this species is found) and abundance, expressed as projective cover of this species in the field (more than 15 % to the field area (Tanskii et al., 1998).

Procedure of map drawing:

The map is made by results of the analysis of the open-published cartographical materials and literature. The map of E. Hulten & M. Fries (1986) was taken as a prototype, supplemented by maps of distribution from A. I. Tolmachev (1976), S. S. Kharkevich (1989). The northern, southern, western and eastern boundaries of area are outlined according to E. Hulten & M. Fries (1986) and amplificated according to V. L. Komarov (1936) (northern, southern, western and eastern boundaries), A. I. Poyarkova (1959) (northern and western boundaries), A. I. Tolmachev (1962; 1976) (northern and eastern boundaries). The sporadic distribution given according to E. Hulten & M. Fries (1986), Poyarkova (1959), A. I. Tolmachev (1976), S. S. Kharkevich (1989). The zone of weediness is determined after T. N. Ul'anova (1981) and V. V. Nikitin (1983) and specified according to data on abundance, frequency of occurrence or weediness of the weed, taken from the below-mentioned references (for exception Manuals and Flores). Within the weed area the zones of occurence and abundance (Tanskii et al., 1998) - occurence of Vicia villosa exceeded 50% with its abundance 3 - 5 number.
