Date of creation:

28.09.2004.

Scale:

1:20,000,000.

Exactness of map:

Map was created using maps of scale 1:50,000,000, 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. 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 locations of species were obtained from Malyshev & Peshkova (1979) and the V.L. Komarov Botanical Institute. Polygons were constructed using species distribution data from floristic regions from Malyshev & Peshkova (1990) and Tzvelev (1976). Final legend of map is bi-colored. Dark points represent locations of species that were determined using herbarium data. Light points represent species locations derived from published sources. 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.
