Scale:

1:20 000 000.

Exactness of a map:

The map was created using maps that had the following scale 1:10 000-1:25 000 000.

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:

For construction of the area of Avena persica the published maps of part of area (Grossheim, 1939; Grasses of Ukraine, 1977; Vasculare Plant of Soviet Far East, 1985) data of N.I. Vavilov All Russian Institute of Plant Industry (VIR), St.-Petersburg) and herbaria data (Komarov Botanical Institute (BIN), (St.-Petersburg) were used. According to literary data the species has distributed across Moldova, Ukraine, Crimea, Caucasus territories and mountain part of Central Asia (Flora of the USSR, 1945; Flora of the European part of the USSR, 1974; Tzvelev, 1976; Brezhnev, Korovina, 1980). Invasive at Far East.The presented area created by data generalization is three separated polygons (green line) and separate points. The points, which were not included into borders of contours, represent single sites of the species. The definition of area border is based on all available data which have no significant contradictions.
