Exactness of map:

The map was created using maps of scale 1:10,000,000-1:80,000,000.

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 polygons and points. Locations of species are represented by points, while the area of possible distribution of the species is represented by polygons.

Exactness of classifier:

Light-colored points represent species locations referenced in published sources. Dark-colored points represent species locations reported in the VIR database (N.I. Vavilov All-Russian Research Institute of Plant Industry). Polygons are based on published sources, herbarium samples, political boundaries and ecological descriptions.

Method of map construction:

The species distribution area was mapped using published maps and materials from the Vavilov Institute. Literature used includes the map of Medicago sativa distribution from Grossheim (1952), Ivanov(1980), Sinskaya (1948), Polozhiy & Malyshev (1994) and the VIR database. The final distribution area also takes into account the ecological preferences of the species.
