Date of creation:

30.09.2004.

Scale:

1:20,000,000.

Accuracy of map:

The minimal territorial unit consists of regional (oblast) arable territories, which were selected using the arable map and generalized to the scale of 1:20,000,000.

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. Points represent recorded locations of the species; polygons represent area of possible distribution of the species.

Accuracy of classifier:

Polygons are based on literature sources, political boundaries and ecological descriptions. Point data were obtained from literature sources.

Method of map production:

Historical agricultural statistics were reviewed at the regional level. The former Soviet Union has 16 regions. The boundaries from the 1:4,000,000 map of arable lands were used to further refine crop distribution (Koroljeva et al., 2003).
