Authors:

Expert botanist T.N. Smekalova
GIS-expert G.V. Talovina

Date of creation:

20.11.2003

Scale:

1:20,000,000.

Accuracy of map:

Map was created using data from herbarium specimens and maps of scale 1:10,000,000-1:80,000,000.

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, while actual location occurrence is shown by points.

Accuracy of classifier:

Point data were obtained from published sources and herbarium specimens. Light-colored points represent species locations referenced in published sources. Dark-colored points represent locations from which herbarium samples were taken (Vavilov All-Russian Research Institute of Plant Industry, Komarov Botanical Institute, Rostov State University, Rostov Botanical Garden, Uljanovsk Educational State University). 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. Literature cited includes Grossgheim (1950), Bush (1939), Dorofeev (1998, 2002), Hulten & Fries (1986), and Kharkevitch (1988). Occurrence data were obtained from herbarium specimens, floras, monographs and papers (Komarov Botanical Institute, Vavilov Research Institute of Plant industry, Rostov Botanical Garden, Rostov State University, Uljanovsk Educational State University). 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.
