Date of creation:



1:20 000 000.

Accuracy of the map:

It is created on materials of maps of natural scale 1:5 000 000 - 1:80 000 000 and on literature data.


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

Basic contents:

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:

Within the weed area the zones of main and sporadic distribution and the zone of weediness are shown, where M.canadensis is a pernicious weed. The zone of weediness is established by criteria of occurence of this species and abundance (Tanskii V.I. et al., 1998). In the limits of this zone M.canadensis is characterized by 75-100% frequency of occurrence and 4-5 points of abundance.

Procedure of map drawing:

Areas of main distribution, sporadic distribution and weediness are established according to the analysis of the open-published maps and literature. The area of M.canadensis is based on the map taken from Hulten E.& Fries M. (1986). Limits of the zone of weediness are established according to Ulyanova T.N. (1983; 1998), being specified in accordance with data on abundance and frequency of the species occurrence, which are taken from below-mentioned references, and adjusted to the limits of arable lands. According to Ulyanova T.N. (1998), M.canadensis is a pernicious weed of soy and other tilled crops, as well as of grain crops in the south of the Far East.
