Basic content:

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

Accuracy of the classifier:

Within the weed area of Descurainia Sophia 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) - where the occurence of this species exceeded 20% with its abundance (projective cover) more than 15%.

Procedure of map drawing:

The areas of distribution and weediness of Descurainia Sophia are established according to the analysis of the open-published maps and literature. The area of distribution is based on the map from the publications of E.Hulten & M.Fries (1986) and A.N.Volkov (1935). Northern limit of the area is adjusted to that of E.Hulten & M.Fries (1986). The area of weediness is established according to V.V.Nikitin (1983) and coordinated with the limits of arable land. The sites of sporadic distribution of Descurainia Sophia, in addition to the data of E.Hulten & M.Fries (1986), are depicted in the north of European part of the Former Soviet Union by A.I.Tolmachev (1976) and literature data - A.A.Bulavkina (1927) and V.V.Byalt (1999), in the Far East they are established according to S.S.Kharkevich (1988) and literature sources (Shlotgauer & Nebaikin,1984; Shaga, 1989). The sites of sporadic distribution of this species within Caucasus by A.A.Grossgeim (1950) are included in the main area, what agrees with the data of A.N.Volkov (1935) and E.Hulten & M.Fries (1986).
