Date of creation:

11.11.2004.

Scale:

1:20 000 000.

Accuracy of a map:

Map is based on data from herbarium specimans and specified on maps having the following scale - 1:10 000 000.

The projection:

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

Basic content:

Map is a vector fail consisting of polygon and points. Locations of species are represented by points, area of possible distribution of species are represented by polygon.

Accuracy of the qualifier:

Lidht-colored points are locations referenced in literature sources. Dark-colored points are locations of species that were reported from herbarium samples. Polygon is based on generalized information from literature sources, herbarium specimans, political boundaries and ecological description.

Method of map construction:

As materials for development of species area map materials from herbarium collections (Komarov Botanical Institute, Moscow State University, Vavilov Institute of Plant Industry, BPI Far East branch of Russian Academy ot Sciences, Uljanovsk Pedagogical State University, Rostov State University, Voronezh State University (geography faculty)), the published maps of area (Grossheim, 1950), and the literary data (Flora of the USSR, 1939, Flora of Tadjikistan, 1975, the Manual of plants of Middle Asia, 1988) have served. The area of species consists of three ranges - Crimean, Caucasian and Central Asian. The Crimean range covers a southern part of the Crimean peninsula, Caucasian - practically all territory of Caucasus within the limits of the former USSR. Thus in mountain areas the species does not rise above the average a mountain belt. In the Central Asian part of the former USSR the species occupies practically all territory of Middle Asia, except for high mountains of Pamir. The points which were not included into borders of ranges, represent invasive habitats of species.
