Scale:

1:20 000 000.

Accuracy of the map:

The map is based on data of herbarium specimens and on 1:10 000 000-1:13 000 000 scale maps.

Projection:

"Albers Equal-Area Conic Projection for USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0

Basic contents:

The map is a vector file consisting of polygons and dots. The localities of the species are represented by the dots; the area of species distribution is represented by the polygons.

Accuracy of the qualifier:

The dots represent information on the species localities according to published sources and herbarium specimens. The polygons are based on generalized information from published sources and herbarium specimens.

Method of the map contruction:

The data on the species distribution were obtained from the database of the species localities coordinates included in the Information Retrieval System "Crop Wild Relatives in Russia" (STC Informregistr 0229905883, 1999), and from the published maps by Grossheim (1945) and Kubli in "Ranges of trees and shrubs of the USSR" (1977).
The range borders in the Western Transcaucasia are drawn after Grossheim (1945) and corrected according to LE and WIR Herbarium materials referred to in the database of the Information Retrieval System; the range borders in the Eastern Transcaucasia are based on LE and WIR Herbarium materials, distribution in Karabakh is cited according to Kubli (1977) with emendations based on LE and WIR Herbarium materials.
