Scale:

1:20 000 000.

Exactness of a map:

The map was created using maps that had the following scale 1:25 000-1:80 000 000.

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 polygon and points. Locations of species are represented by points, area of possible distribution of species are represented by polygon.

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). Polygon is based on literature sources, herbarium samples, political boundaries and ecological description.

Method of map construction:

For construction of the area of Vicia tenuifolia the published maps of areas (Flora of Siberia, 1994; Hulten, Eric and Magnus Fries, 1986;) and herbaria data (Komarov Botanical Institute (BIN) and N.I. Vavilov All Russian Institute of Plant Industry (VIR), St.-Petersburg) were used.The presented area created by data generalization is the polygon (green line) and separate points. The polygon occupies European and Siberian territory of former USSR, Kazakhstan, Kirghizia, Uzbekistan and Tadjikistan (except dry steppe and desert areas). Our point of view for distribution of species on the territory of Russia and the adjacent states partly coincides with understanding of the area of species by Hulten, Eric and Magnus Fries (1986). The eastern part of the area is based on the published map (Flora of Siberia, 1994). The points, which were not included into borders of areas represent the local sites of the species. 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 the European part of the USSR. 1987) which had no significant contradictions.
