1:20 000 000.Accuracy of a map:
Map is based on data from herbarium specimans and on maps having the following scale: 1:13 000 000-1:50 000 000.The projection:
"Alber's Equal Area Conic for Russia", 9, 1001, 7, 100, 0, 44, 68, 0, 0Basic contents:
Map is a vector file consisting of polygons and points. Locations of species are represented by points, areas of possible distribution of species are represented by polygons.Accuracy of the qualifier:
Points represent locations of the species referenced in literature sources and from herbarium specimens. Polygons are based on generalized information from literature sources and herbarium specimens.Method of map contruction:
The data on distribution of the species were obtained from database of site coordinates of the species, in the Information Retrieval System "Wild-growing relatives of cultural plants of Russia" (NTC "Informregistr" #0229905883) and published maps of Grossgeim (1980), Svjazeva (1980), Kurbatsky for "Flora of Siberia. Rosaceae" (1988), Koropachinskiy (2002).Mainly borders of the area are carried according to Svjazeva's maps (1980) and corrected on the basis of herbarium materials, stored in a database of the Information Retrieval System "Wild-growing relatives of cultural plants of Russia" (1999). In Siberia the eastern and south-eastern borders are constructed out on Kurbatsky's maps (1988). Northern border of area on Kopet Dagh and western border on Pamiro-Alai has been expanded on the basis of herbarium materials. In Transcaucasia borders of the area are carried according to Grossgeim's data (1952), in Talysh borders of the area are carried out on Grossgeim's data (1952) and corrected on the basis of herbarium materials.
As for our opinion points beyond the border of the polygon on peninsula Mangyshlak (Kazakhstan) shoud not be included into basic area.
