Date of creation:



1:20 000 000.

Accuracy of map:

Map was created based on maps of natural scale 1:5 000 000 and on literature data.


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

Basic contents:

Vector map. Area of species distribution is shown by polygons, and sporadic distribution by points. Zones of weediness are shown by polygons.

Accuracy of classifier:

The weed area is subdivided into two zones, one representing species distribution, and the second where species is considered a serious weed. Points represent locations where sporadic occurrence has been reported. The zone of weediness was established according to the criteria of occurrence and abundance of this species base on the work of Tanskii et al. (1998). With the limits of this zone S. Montana is characterized by having a 25-50% frequency of occurrence and 2 points of abundance.

Method of map production:

Published literature was reviewed, including Atlases, monographs and papers. Occurrence data were obtained from herbarium specimens, floras, monographs and papers. The area of main distribution of S. montana was determined according to the following sources: Grossgeim (1967), Nikonov (1975), Geideman (1954), Visyulina (1970), Rubtsov (1972), Aleksandrova et al. (1975), Maevskii (1954), Elenevskii et al. (2001), Galushko (1980), Takhtadzhyan (1987), Karyagin (1957), Ulyanova (1989), Vvedenskiy (1960, 1961), Nikitin (1954, 1979), Vasilchenko (1953), Pavlov (1964). Limits of the zone of weediness were established according to Nikitin (1983), and adjusted according to the data on abundance and frequency of the species occurrence, which are taken from below-mentioned references, and adjusted to the limits of arable lands (Koroljeva et al., 2003). According to Nikitin (1979, 1983), S. Montana does not heavily infest grain crops in the steppe zone of the European part of the former USSR and in Central Asia. According to data of Ulyanova (1989) S. montana infests cotton crops in all cotton-growing regions of Central Asia. Data were then compiled through scanning and geo-referencing to develop a composite vector map. The biologist, together with the GIS specialist, drew a composite weed distribution area based on compiled data.
