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:

Within the weed area of P. alopecuroides, the zones of its weediness are shown, established by criteria of occurence (% 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 occurence of this species exceeded 20% with its abundance (projective cover) more than 15%.

Method of map production:

The areas of distribution and weediness of P. alopecuroides are established according to the analysis of the open published maps and literature. The area of distribution is based on the map from the publication of Volkov A.N. (1935). The zones of weediness are established according to Agaev M.G. (1989) and Pak K.I. (1959) and specified by the border of arable land. The sites of sporadic distribution of P. alopecuroides are depicted according to Grossgeim A.A. (1952), ILDIS database (Roskov, 2005) and Krylov P. (1933), part of them, supported by the data of Volkov A.N. (1935), is included in the main area.
