Date of creation:



1:20 000 000.

Accuracy of map:

Map was created based on materials of maps of natural scale 1:15 000 000-1:100 000 000 and on information taken from open-published literature.

Basic contents:

Vector map. Area of species distribution is shown by polygons and sporadic distribution by points. Zones of weediness are shown by polygons.

Accuracy of classifier:

The weed area is subdivided into two zones, one representing species distribution, and the second where the weed is considered a serious pest. Points represent locations where sporadic occurrence has been reported. Within the weed area the zones of weediness are presented where C. europaea is pernicious. The zones of weediness were established according to criteria of occurrence (15% of fields where this species is found) and abundance, expressed as projective cover of this species in the field (more than 10% to the field area), as established according to Tanskii et al. (1998).

Method of map production:

Published literature was reviewed, including Atlases, monographs and papers. Occurrence data were obtained from herbarium specimens, floras, monographs and papers. The maps of Hulten & Fries (1986) were used as a prototype and were supplemented by maps of species distribution published by Tolmachaev (1976). The northern, southern, western, and eastern boundaries of main area were outlined according to Hulten & Fries (1986). The sporadic distribution was presented according to Hulten & Fries (1986), Kharkevich (1995) and Tolmachaev (1976). The zone of weediness was determined according to the following sources: Shlyakova (1982), Nikitin (1983), Ulyanova (1998); and specified according to data on abundance, frequency of occurrence or weediness of the weed, taken from the below-mentioned references (except for the Manuals and Floras). Within the weed area the zones of weediness were outlined according to criteria of occurrence and abundance (Tanskii et al., 1998), i.e., where the occurrence of C. europaea exceeds 20% with its abundance at 2-3 points. Data were then compiled through scanning and geo-referencing to develop a composite vector map. The biologist, together with the GIS specialist, drew a composite weed distribution area based on compiled data.
