Date of creation:

28.09.2004.

Scale:

1:20,000,000.

Accuracy of map:

The map was created using maps of scale 1:50,000,000, 1:30,000,000, 1:10,000,000, and 1:5,000,000.

Projection:

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

Basic contents:

Vector map. Area of species distribution is shown by polygons, while actual location occurrence is shown by points.

Accuracy of classifier:

Point data were obtained from published sources and herbarium specimens. Light points represent species locations referenced in published literature. Dark points represent locations from which herbarium specimens were taken. Polygons are based on published sources, herbarium samples, and field surveys by the authors.

Method of map production:

Published literature was reviewed, including atlases, monographs and papers. Occurrence data were obtained from herbarium specimens, floras, monographs and papers. Point area includes species locations reported in Tolmachev (1974), Grossgheim (1939), Shelyak-Sosonko (1977), Malyshev & Peshkova (1979), Kharkevich (1991), Hulten & Fries (1986), and the V.L. Komarov Botanical Institute. Polygon areas were determined using species distribution data from Malyshev & Peshkova (1990), Tzvelev (1976), and Hulten & Fries (1986). The final map legend is bi-colored. Dark points represent locations from which herbarium specimens were taken. Light points represent species locations referenced in published literature. The polygon is the result of integrating accurate species distribution maps with the state borders of Russia. The northern border was mapped using Tolmachev (1974) and Hulten & Fries (1986). The southern border was mapped using data from the herbarium of the V.L. Komarov Botanical Institute, Hulten & Fries (1986) and the border of the former USSR. Several points were not included in the polygon, as they could represent sites of invasion. 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.
