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.

Exactness of classifier:

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

Method of map construction:

The cultivated area of Festuca ovina is founded on the base of agroclimatic, natural and economical principles of former USSR countries territory division. The vast information on the problem published in open press was analyzed. The final map was constructed by generalization of regions. maps, arable-lands. map (dark blue polygon), map of lands permitted for cultivation without non-arable-lands (light blue polygon). Only those lands where Festuca ovina took place in crop rotation were taken into account.
