Date of creation:

07.06.2004.

Scale:

1:20,000,000.

Accuracy of map:

Map was created using information from state publications and maps of natural scale 1:13,000,000-1:80,000,000.

Projection:

"Alber's Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

Vector map. Main distribution area is shown by a polygon. Zone of weediness is shown by a polygon.

Accuracy of classifier:

Distribution area of the species is divided into zones of main distribution, moderate weediness, and sporadic distribution.

Mapping procedure:

Distribution area and zone of weediness were mapped following an analysis of public cartographic materials. The map by Hulten & Fries (1986), containing the presumed distribution area, was used as a basis for the distribution area map of P. annua; it was corrected using herbarium and published data. The northern border of the main distribution area in European Russia was specified according to Shlyakova, 1978; Shishkin, 1955; Fedorov, 1974; Andreev et al., 1987; Ramenskaya, 1966; and herbarium materials. The species inhabits western regions of the former USSR (Geideman, 1954; Prokudin, 1987; Andreev et al., 1987) and the Caucasus (Grossgeim, 1939). Its distribution in Central Asia has been recorded in Vasil.eva et al. (1964) and has been coordinated within the boundaries of arable and desert lands. Its distribution in Siberia is supported by Hulten & Fries (1986), Popov (1957), Krasnoborov (1979) and herbarium data. Its distribution in the Far East was corrected using Kharkevich (1985) and Tolmachev (1966) and coordinated within the boundaries of arable lands. The zone of weediness was mapped using Nikitin (1983) and corrected using data on abundance, occurrence and harmfulness of the weed; these data were taken from the below-mentioned references and coordinated within the boundaries of vegetable-growing lands, as they suffer from the weed most of all (Keller, 1934). Patches of sporadic distribution were taken from cartographic and published data (Hulten & Fries, 1986; Kharkevich, 1985).
