Date of creation:

Scale:

1:20 000 000.

Accuracy of the map:

It is created on materials of map of natural scale 1:15 000 000 and on literature data.

Projection:

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

Main content:

Vector map. Area is shown by polygons (main distribution) and by dots (sporadic distribution). Zone of harmfulness is shown by polygons.

Accuracy of the classifier:

The distribution of the species is divided into zones of main distribution, sporadic distribution, and harmfulness area. The zones of weediness are shown - established by criteria of occurence (50% of fields where this species is found) and abundance, expressed as projective cover of this species in the field (more than 15 % to the field area (Tanskii et al., 1998).

Procedure of map drawing:

Zones of distribution and injury are allocated by results of the analysis of the open-published cartographical materials and literature, and also materials of the VIR Herbarium of weed plants. The area of distribution has been outlined after Nikitins materials (1983) and Shishkin and Bobrov (Eds.,1949), and then it has been specified according to the publications listed below. Northern border is located within the steppe zone. A. theophrastii is an adventive plant in the Far East. Now it is distributed on arable Primorskii and Khabarovskii Territoris (Kharkevich,1987). The zone of damage is allocated after the literature data with adjustment to arable lands. It is located in areas of irrigated agriculture of the European part, Crimea, on Caucasus, in Central Asia. Litters crops of a cotton, millet, flax, on fields tilled cultures (Vasilchenko, 1975; Deza, 1989; Dobrokhotov, 1961; Maisuryan, Atabekova, 1978; Ulyanova, 1998). On the Far East and in Primorski Krai Abutilon is an insignificant weed on fields (Shishkin, 1936; Vorobev et al, 1966).
