Date of creation:



1:20 000 000.

Accuracy of map:

The map was created using maps that had the following scale 1:25 000 000-1:40 000 000.

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, 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. Light-colored points are locations of species referenced in literature sources. Dark-colored points are locations of the species that were as reported from the VIR database (N.I. Vavilov Institute, 2003).

Method of map production:

Published literature was reviewed, including Atlases, monographs and papers. Literature used included: Grossgheim (1952); Meusel et al. (1965) and VIR database (N.I. Vavilov Institute, 2003. Occurrence data were obtained from herbarium specimens (N.I Vavilov All-Russian Institute of Plant Industry), 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.
