Date of creation:

13.11.2003

Scale:

1:20,000,000.

Accuracy of map:

Map is based on data from herbarium specimens and on maps of scale 1:17,000,000-1:50,000,000.

The projection:

"Alber's Equal Area Conic for Russia", 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

Map is a vector file consisting of polygons and points. Points represent locations of species; areas of possible distribution of species are represented by polygons.

Accuracy of classifier:

Points represent locations of the species referenced in published sources and locations from which herbarium specimens were taken. Species location data were obtained from a database of site coordinates developed by the N.I. Vavilov Institute (1992) and from published maps (Polozhiy, 1994; Koropachinskiy, 1983, 2002; Pimenova, 1983; Hulten & Fries, 1986). Polygons are based on generalized information from published sources and herbarium specimens.

Method of map production:

Published literature was reviewed, including atlases, monographs and papers. Occurrence data were obtained from herbarium specimens, 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.
