Accuracy of map:

Map was created using maps of scale 1:2,000,000-1:11,250,000.

Projection:

"Alber's Equal Area Conic for the USSR", 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. 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. The herbarium of the V.L. Komarov Institute and the following sources were used to determine the species distribution area: Shelyag-Sosonko (1997), Tzvelev (1974), Malyshev & Peshkova (1979), and Hulten & Fries (1986). Within the European part of the former USSR, the northern border of the distribution area passes along the borders of the northern and central taiga zone; in Siberia, the distribution area border travels south along the border between the central and southern taiga; the southern border passes along the border between the steppe and semi-desert zones. Separate sites of species occurrence were found in the Yakut hollow. In Central Asia, this species grows in mid-elevation mountains. In the Far East, the species occurs in the zone of coniferous broadleaved woods of the Primorski Krai and Amur regions, the Kuriles and the Southwestern Kamchatka peninsula. Data were 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.
