Scale:

1:20 000 000.

Exactness of a map:

The map was created using map that had the following scale 1:40 000 000.

The projection:

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

Basic contents:

Map is a vector file consisting of polygons and points. Locations of species are represented by points, area of possible distribution of species are represented by polygons.

Exactness of classifier:

Light-colored points are locations referenced in literature sources. Dark-colored points are locations of the species that were as reported from created database VIR (N.I.Vavilov All-Russian Research Institute of Plant Industry) and BIN (the Komorov Institute of Botany). Polygons are based on literature sources, herbarium samples, political boundaries and ecological description.

Method of map construction:

For construction of the area of Vicia costata the published maps of areas ( Flora of Siberia, 1994) herbaria N.I. Vavilov All Russian Institute of Plant Industry (VIR), St.-Petersburg) and herbaria data (Komarov Botanical Institute (BIN), St.-Petersburg) were used. The species originates from the territory of Mongolia and North-Western China. The sites of the species at the territories of the Southern part of Central Siberia and the part of Central Asia correspond to north- western part of the species area. Final species area for Russian territory represents the polygon (green line) and separate points. The western border of the area defined according VIR and BIN herbarium data, , eastern border - according to Flora of Siberia (1994), northern border is extended to the north on the base of herbarium data and Flora of Siberia (1994).
In the definition of the border of the area we took into account biological and ecological peculiarities of the species and all available literary data (Field Guide of Plants of Central Asia, 1981; Flora of cultivated plants, 1999; Flora of Kazakhstan, 1961; Flora of the USSR, 1948; Flora of Central Siberia, 1979) which had no significant contradictions.
The points, which were not included into borders of contours, represent secondary, invasive sites of species.

Sources of the data:

Flora of Siberia. 1994. Polozhiy A.B., Malyshev L.I., (ed.). - Novosibirsk: Nauka, Vol. 9. - 280 pp. (in Russian).
Created database of the VIR materials (N. I. Vavilov Allrussian Institute of Plant Industry) and BIN materials (the Komorov Institute of Botany).
