Date of creation:

22.09.2004

Scale:

1:20,000,000.

Accuracy of map:

Map was created using maps of scale 1:13,000,000-60,000,000 and data from herbarium specimens.

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 species locations are 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. Light-colored points represent locations of species referenced in published sources. Dark-colored points represent locations of species from which herbarium samples were taken (Moscow State University and N.I. Vavilov All Russian Institute of Plant Industry).

Method of map production:

Published literature was reviewed, including atlases, monographs and papers. Occurrence data were obtained from herbarium specimens (Moscow State University, N.I. Vavilov Institute), floras, monographs and papers. Our mapped species distribution area within Russia and the adjacent countries coincides with the work of Mosel (1965). The distribution area has a disjunctive character and consists of three polygons: European, Crimean and Caucasian. The European polygon covers Moldova and the Western Ukraine. The Crimean polygon covers the southern, mountainous part of the Crimean peninsula. Within the Caucasian polygon, distribution of the species from the southeast and southwest is limited by the Black and Caspian Seas and frontiers. Northern and eastern borders of the polygon practically coincide with the borders specified by Mosel (1965); it is different, however, in the southern part of the Kuban river basin. Points of species distribution that were not used to create the borders of the polygons represent secondary, invasive sites of the species. The following sources were used: Mosel (1965), Cherepanov (1995), and Grossgeim (1967). 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.
