Scale:

1:20 000 000.

Accuracy of the map:

The map is based on data of 1:13 000 000 - 1:80 000 000 scale maps, specified according to herbarium materials.

Projection:

"Albers Equal-Area Conic Projection for USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0

Basic contents:

The map is a vector file consisting of 1 basic and 2 subject layers. The species range is represented by polygons and dots.

Accuracy of the qualifier:

The dots represent information on the species localities: 1 - reliable data from herbarium and published sources; the polygons (1) - generalized information on the species distribution from published sources and herbarium specimens.

Method of the map construction:

The data from the herbarium materials of LE, published data (Rozhevits, Shishkin, 1934; Pavlov, 1956; Fedorov, 1974; Tzvelev, 1976; Malyshev, Peshkova, 1979), and published maps of the range (Meusel et al., 1965; Hulten, Fries, 1986) and the range parts (Grossheim, 1939; Shelyag-Sosonko, 1977; Malyshev, Peshkova, 1990) were used for constructing the range of Elymus caninus. Our view on the species distribution in Russia and adjacent states mainly coincides with the treatment of the species distribution by Meusel et al. (1965), and Hulten, Fries (1986). The range consists of two polygons and dots. We have extended the borders of the main polygon based on the herbarium and published data. The larger polygon embraces the European part of the former USSR, northeastern Kazakhstan and Siberia. The smaller polygon is situated in the Balkash Lake area. Dots beyond polygon borders represent specific localities of the species.
