Scale:

1:20,000,000.

Accuracy of map:

Map was created using herbarium specimens and maps of scale 1:30,000,000.

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 a polygon and points. Locations of the species are represented by points, while the area of possible distribution of the species is represented by a polygon.

Accuracy of qualifier:

Light-colored points represent species locations referenced in published sources. Dark-colored points represent locations from which herbarium samples were taken (N.I. Vavilov All-Russian Research Institute of Plant Industry, Komarov Botanical Institute). Polygon is based on generalized information from published sources, herbarium specimens, political boundaries and ecological descriptions.

Method of map construction:

Locations and area of distribution of the species are based on published maps and herbarium materials from the Komarov Botanical Institute, Vavilov Research Institute of Plant Industry. The prototype for this map is the map of Ribes biebersteinii distribution by Poyarkova (1936), which was further specified using herbarium materials.
