Date of creation:



1:20 000 000.

Accuracy of the map:

It is created on materials of maps of natural scale 1:5 000 000 - 1:80 000 000 and on literature data.


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

Basic contents:

Vector map. Area 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 area of main and sporadic distribution and the zone of weediness are shown where H.niger is a pernicious weed. The zone of weediness is established by criteria of occurrence of this species and abundance (Tanskii et al., 1998). In the limits of this zone, H. niger is characterized by 10-25% frequency of occurrence and 2 score-points of abundance.

Method of map production:

Areas of main distribution, sporadic distribution and weediness are established according to the analysis of the open published maps and literature. The area of H. niger is based on the map taken from Chikov P.S. (1983). Limits of the zone of weediness are established according to Ulyanova T.N. (1981), specified in accordance with data on abundance and frequency of the species occurrence, which are taken from the following references and adjusted to the limits of arable lands. According to Ulyanova T.N. (1981), H. niger is a pernicious weed of wheat in the European part of the former USSR (except the Non-Chernozem region of Russia), Western Siberia, Caucasus, Central Asia. Sporadic distribution is shown according to Hulten, E. & Fries, M. 1986, Dorogostaiskaya E.V. (1972), Grossgeim A.A. (1967), Polozhii A.V. & Peshkova G.A. (1996), Tolmachev A.I. (1977), Kharkevich S.S. (1995).
