Scale:

1:20 000 000.

Exactness of a map:

The map was created using maps that had the following scale 1:25 000 000-1:40 000 000.

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. Locations of species are represented by points, area of possible distribution of species are represented by polygons.

Exactness of classifier:

Light-colored points are locations referenced in literature sources. Dark-colored points are locations of the species that were as reported from created database VIR (N.I.Vavilov All-Russian Research Institute of Plant Industry) and BIN ( the Komorov Institute of Botany). Polygons are based on literature sources, herbarium samples, political boundaries and ecological description.

Method of map construction:

Location and area of distribution The area of aof the species is based on a rezults of published maps and analysis of materials from the Vavilov Institute. Literature used included: The basis of this area are: the map of Trifolium fragiferum distribution from Grossheim A. A. (1952); Hulten, Eric and Magnus Fries. (1986), Meusel Y. und and.(1965), Flora ...(1976, 1994); and database of VIR. Points not included in polygon represent invasion by the species. Areal Final area also takes into account the ecology data from .Descriptions..
map was made taking into account ecology data from .Descriptions..
