Accuracy of map:

Map was created using herbarium specimens and maps of scale 1:10,000,000-1:25,000,000.

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. Points represent locations of the species. The area of possible distribution of the species is represented by a polygon.

Accuracy of classifier:

Light-colored points represent species locations referenced in published sources. Dark-colored points represent locations from which herbarium samples were taken (N.I. Vavilov Institute, Komarov Botanical Institute, Rostov State University, Siberian Branch of the Russian Academy of Science). Polygon is based on generalized information from published sources, herbarium specimens, political boundaries and ecological descriptions. Literature consulted includes Grossgheim (1950), Bush (1939), Dorofeev (1998, 2002), Malyshev & Peshkova (1994), Harkevich (1988), and Cherepanov (1995).

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.
