1:20 000 000.Accuracy of the map:
It is created on materials of maps of natural scale 1:5 000 000 and on literature data.Projection:
"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 E. armoracioides is a pernicious weed. The zone of weediness is established by criteria of occurrence and abundance of this species (Tanskii V.I. et al., 1998). In the limits of this zone, E. armoracioides is characterized by 25% frequency of occurrence and 2 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 E. armoracioides is drawn according to maps (Grossgeim A.A., 1950; Nikonov A.A., 1975) and data of Brezhnev D.D. & Korovina O.N. (1981), Nikitin V.V. (1979; 1983), Keller B.A. et al. (1934), Gubanov I.A. et al. (2003), Ulyanova T.N. (1981), Visyulina O.D. (1970). Limits of the zone of weediness are established according to Nikitin V.V. (1979; 1983), Ulyanova T.N. (1981), Visyulina O.D. (1970), 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 Nikitin V.V. (1979; 1983), E. armoracioides infests grain crops in steppe zone of the European part of the former USSR, Central Asia, Southern Kazakhstan and Western Siberia. According to Ulyanova T.N. (1981), E. armoracioides is a pernicious weed of wheat in Northern Kazakhstan. Data of Visyulina O.D. (1970) confirm distribution of E. armoracioides in crops in steppe zone of the Ukraine and in Crimea. Sporadic distribution is shown according to Grossgeim A.A. (1950), Malyshev L.I. & Peshkova G.A.(1994).Reference citations:
