Scale:

1:20,000,000.

Accuracy of map:

Created using maps that had the following scale 1:25,000,000-1:40,000,000.

Projection:

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

Basic contents:

Vector file consisting of polygons.

Accuracy of classifier:

Polygons are based on literature sources, political boundaries and ecological description.

Method of map production:

The map is based on the intersection of the Arable Land Map (Koroljeva et al, 2003) and maps indicating where this species is permitted to be grown, based on the "Catalog of state permitted cultivars of agricultural crops." (Only those lands where M. varia took place in crop rotation were taken into account).
