Date of creation:

20.05.2005.

Scale:

1:20 000 000.

Accuracy of map:

It is created on materials of maps of natural scale 1:15 000 000-1:100 000 000 and on information taken from the open-published literature.

Projection:

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

Basic contents:

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

Accuracy of the classifier:

Within the weed area the zones of weediness are shown according to occurrence and abundance (Tanskii et al., 1998), i.e., occurrence of O. aegiptiaca exceeds 50% with its abundance 4-5 points.

Procedure of map drawing:

The map is made by results of the analysis of the open-published cartographical materials and literature. The map of A.N. Volkov (1935) has been taken as a prototype. The northern, southern, western, and eastern boundaries of the area are outlined according with A.N. Volkov (1935). The sporadic distribution is given according with E.V. Vul.f (1969) and data of BIN RAN herbarium (LE). The zone of weediness is determined after V.V. Nikitin (1983), T.N. Ul.yanova (1998), V.V. Nikitin, M.A. Andreev & P.V. Aleksandrov (1948), D.T. Kabulov & Kh.M. Mukumov (1965), I.G. Beilin (1986), V.V. Nikitin & A.M. Geldikhanov (1988), I.T. Vasil.chenko & O.A. Pidotti (1975) and specified according with data on abundance, frequency of occurrence or weediness of the weed, taken from the below-mentioned references (except "Keys" and "Floras").
