Authors:

Object specialist N.N. Luneva,
GIS-specialist I.A. Budrevskaya.

Date of creation:

10.03.2005.

Scale:

1:20 000 000.

Accuracy of map:

Map was created based on information taken from open-published literature and maps of scale 1: 5 000 000 - 1: 100 000 000.

Projection:

"Alber's Equal Area Conic for the 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 weed is considered a serious pest. A zone of moderate weediness was determined according to a criteria of occurrence (% of fields where this species is found) and abundance (Tanskii et al., 1998), i.e., where the occurrence of this species exceeded 50% with its field abundance (projective cover) being more than 15%. Points represent locations where sporadic occurrence has been reported.

Method of map production:

Published literature was reviewed, including Atlases, monographs and papers. Occurrence data were obtained from herbarium specimens, floras, monographs and papers. Data on L. patula distribution in Russia taken from Keller (1934) was used.. Modern general distribution of the species is supported by the following references: Ul.yanova (1981), Nikitin (1983), Gubanov (2004). The zone of main distribution in the European part of Russia and adjacent CIS countries was confirmed and corrected according to the following literature data: Maevskii (1954), Dorogostaiskaya (1972), Shishkin (1957), Blagoveshchenskii (1966), Zernov (2002), Bakin et al. (2000), Baranova et al. (1992), Prudnikov & Poluyanov (1996), Yanchurkina (1980), Geideman (1954), Rubtsov (1972). The species occurrence in the North Caucasus and Transcaucasia was confirmed according to the following sources: Grossgeim (1967), Galushko (1980), Vasil.chenko & Pidotti (1975). Its distribution in Central Asia and Kazakhstan was confirmed according to the following literature data: Nikitin & Gel.dikhanov (1988), Vvedenskii (1961), Korovina et al. (1983), Vasil.eva & Matsenko (1964), Vvedenskii (1962), Ikonnikov (1962). The species distribution in Siberia was also confirmed by the literature data of Krasnoborov & Kashina (1979). The zone of weediness was defined according to Nikitin (1983) and was adjusted according to data on weed occurrence, abundance, or harming ability taken from below references (except .Keys. and .Floras.) and adjusted according to maps of steppe zone and arable lands. Sporadic distribution areas were indicated based on herbarium data. 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.
