Date of creation:



1:20 000 000.

Accuracy of map:

Map was created based on data from herbarium specimens and on maps having the following scale: 1:13 000 000-1:50 000 000.

The 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 and actual location occurrence is shown by points.

Accuracy of classifier:

Point data were obtained from literature sources and herbarium specimens. Polygons are based on literature 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. The following sources were used to determine the area of distribution for this species: N.I. Vavilov Institute (1999), Grossgheim (1952), Sokolov et al. (1980), Koropachinskiy (2002). The species has a disjunctive area. The western border of the area in the European part of Russia was based on the work of Sokolov et al. (1980). The northern border of the area in the European part of Russia was also determined according to Sokolov et al. (1980). In western Siberia and Ural the herbarium materials registered in the database of the N.I. Vavilov Institute (1999) were used. The southern border in the European part of Russia was determined according to Sokolov et al. (1980) and adjusted according to herbarium materials; in Crimea according to herbarium materials registerned in the database the N.I. Vavilov Institute (1999); in the Caucasus according to Grossgheim (1952); in Northern Kazakhstan according to Sokolov et al. (1980) and adjusted according to herbarium materials. Borders of the second most eastern part of the Altay area were constructed only on the basis of herbarium materials. The most northern point in the European part wasn't included in the final polygon because this location, most likely, is a result of casual invasion. Based on our opinion, the two southern points beyond the border of the polygon also should not be included into the basic area. 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.
