Authors:

Biological specialist - S.Yu. Larina

Date of creation:

15.11.2004

Scale:

1:20,000,000

Accuracy of map:

Map was created using maps of natural scale 1:5,000,000-1:100,000,000.

Projection:

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

Basic contents:

Vector map. Area of species distribution is shown by polygons, while sporadic distribution is shown 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 of Barbarea vulgaris, the zones of its weediness were established according to criteria of occurrence (% of fields where this species is found) and abundance (expressed as projective cover of this species in the field (in % to the field area)), where the occurrence of this species exceeded 20% with an abundance (projective cover) of more than 15% (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 area of distribution of this species was determined based on the maps of Hulten & Fries (1986) and Volkov (1935). The Eastern limit of the area was extended to the territory of the Tymen region according to Ermilov (1961). The areas of weediness were established according to Korovina (1982) and coordinated with the boundaries of the arable land map (Koroljeva et al., 2003). The sites of sporadic distribution of Barbarea vulgaris, in addition to the data of Hulten & Fries (1986), were depicted in the Far East according to Nechaeva (1987) and Kudrin & Yakubov (1995); and in the Caucasus according to Grossgeim (1950). The sporadic distribution of this species in the Northeastern European part of the Former Soviet Union described by Tolmachev (1976) was included in the main area and is supported by Komarov & Bush (1939) and Shlyakova (1990). 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.
