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 area of C. declinatum, 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 C. declinatum are established according to the analysis of the open published maps and literature. The area of distribution is based on the map taken from the publication of A.N.Volkov (1935). The map of V.P.Golubintseva (1936) is used as a reference source. The zones of weediness are established according to V.V.Nikitin (1983) and coordinated with the limits of arable land. The sites of the sporadic distribution of C. declinatum are depicted according to A.N.Volkov (1935), S.S.Kharkevich (1988), S.L.Mosyakin & O.G.Yavorska (2002), I.M.Krasnoborov & L.I.Malyshev (1992); the absolute majority of the last ones, supported by the data of A.N.Volkov (1935), is included in the main area.
