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 and published maps of the range parts (Kharkevich, 1985; Hulten, Fries, 1986; Malyshev, Peshkova, 1990) were used for constructing the range of Elymus mutabilis. Our view on the species distribution in Russia and adjacent states mainly coincides with the treatment of the species distribution by Hulten and Fries (1986). We have somewhat extended the borders of polygons, based on the herbarium and published data (Fedorov, 1974; Rozhevits, Shishkin, 1934; Tzvelev, 1976). The range consists of 3 polygons and dots. The largest polygon covers the northern European Russia, Ural Mountains, and stretches as a belt eastward through northern Siberia to Yakutia, embraces the Lena River basin and takes a large area in the southern Siberia, Altai and the central Siberia. The second polygon is situated in the Kola Peninsula, the third one in Kamchatka. Dots beyond polygon borders represent separate localities of the species.
