Date of creation:

24.12.2003

Scale:

1:20 000 000.

Accuracy of map:

The map was created using maps that had the following scale 1:25 000 000-1:40 000 000.

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. Polygons represent area of possible distribution of the species.

Accuracy of classifier:

Polygons are based on literature sources, herbarium samples, political boundaries and field surveys by the authors.

Method of map production:

Historic agricultural statistics were reviewed at the level of agricultural region. The Former Soviet Union had 16 regions. The boundaries from the 1:4000000 map of Arable Lands were used to further refine crop distribution (Koroljeva et al., 2003). The final map was constructed according to a generalization of regions. maps, arable-lands. map (dark blue polygon), and map of lands permitted for cultivation without non-arable-lands (light blue polygon).
