Authors:The expert-botanist - T.N. Smekalova, the GIS-expert - G.V. Talovina.
Date of creation:04.12.2003.
Scale:1:20 000 000.
Accuracy of map:Map is based on data from herbarium specimens and on maps having the following scale: 1:10 000 000.
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 polygon and points. Points represent locations of species; area of possible distribution of species is represented by polygon.
Accuracy of classifier:Light-colored points are locations referenced in literature sources. Dark-colored points are locations of species that were reported from herbarium samples (N.I.Vavilov All-Russian Research Institute of Plant Industry, Komarov Botanical Institute). Polygon is based on generalized information from literature sources, herbarium specimens, political boundaries and ecological description. Literature used included: (Grossgheim, 1950); (Bush, 1939); (Dorofeev, 1998, 2002); (Tsvelev, 2000).
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.
