"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 S.australis is a pernicious weed. The zone of weediness is established by criteria of occurrence of this species and abundance (Tanskii V.I. et al., 1998). In the limits of this zone, S.australis is characterized by 50-75% frequency of occurrence and 3 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 S.australis is based on the map taken from Volkov A.N. (1935). Data of Grossgeim A.A. (1945) confirm wide distribution of S.australis in the Caucasus. Limits of the zone of weediness are established according to Nikitin V.V. (1983), Melnichuk O.S & Kovalivska G.M (1972), 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. (1983), S.australis infests crops in steppe, semi-desert and desert area in the European part of the former USSR, Crimea, the Caucasus, West and East Siberia, Central Asia. Melnichuk O.S & Kovalivska G.M (1972) point out that S.australis is a widespread weed in Crimea and in steppe zone of the Ukraine. According to Ulyanova T.N. (1981), S.australis infests wheat in the Caucasus, in Crimea, in Central Asia and Northern Kazakhstan. Data of Nikonov A.A. (1975) confirm distribution of S.australis in the steppe zone of the Stavropol Territory. Ten A.G. (1988) includes S.australis in the list of the most widespread weed species in Western Siberia. Belykh A.G. (1974) gives data on wide distribution of S.australis in West Siberia. Sporadic distribution is shown according to Krasnoborov I.M. & Malyshev L.I., (1992), Kharkevich S.S. (1988).
