Date of creation:

Scale:

1:20,000,000.

Exactness of map:

The map was created using maps of 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 a polygon and points. Locations of species are represented by points; area of possible distribution of species is represented by a polygon.

Exactness of classifier:

Light-colored points represent species locations referenced in published sources. Dark-colored points represent species locations reported in the BIN database (the Komorov Institute of Botany). The polygon is based on published sources, herbarium samples, political boundaries and ecological descriptions.

Method of map construction:

In order to construct the distribution area of Elymus confuses, published maps of the parts of the area (Harkevich, 1985; Malyshev & Peshkova, 1990) and herbaria data (Komarov Botanical Institute (BIN), St. Petersburg) were used.
The distribution area created by generalizing this data is represented by a polygon (green line), which corresponds to published data on species distribution (Rozhevitz & Shishkin, 1937; Tzvelev, 1976). The points, which were not used to construct the general distribution area, represent single sites of species occurrence. The distribution area borders take into account the ecological preferences of the species.
