Accuracy of map:

Map is based on data from herbarium specimens and on maps of scale: 1:10,000,000.

The projection:

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

Basic content:

Map is a vector file consisting of a polygon and points. Points represent locations of species; area of possible distribution of species is represented by a polygon.

Accuracy of classifier:

Light-colored points represent species locations referenced in published sources. Publications consulted include Grossgheim (1945), Bush (1939), and Sokolov & Svjazeva (1977). Dark-colored points represent locations of species from which herbarium specimens were taken (N.I. Vavilov Institute; Komarov Botanical Institute; Moscow State University). Polygon is based on generalized information from published sources, herbarium specimens, political boundaries and ecological descriptions.

Method of map production:

Published literature was reviewed, including atlases, monographs and papers. Occurrence data were obtained from herbarium specimens, floras, monographs and papers. Data were then compiled through scanning and geo-referencing to develop a composite vector map. The biologist, together with the GIS specialist, drew a new plant distribution area based on compiled data.
