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. Points represent locations where sporadic occurrence has been reported. The zone of weediness was established according to criteria of occurence of this species and abundance (Tanskii et al., 1998). Within the limits of this zone G. uliginosum was characterized by having a 10-20% frequency of occurrence and 2-3 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 following sources were used to determine the areas of G. uliginosum: Hulten & Fries (1986), Chikov (1983), Tolmachev (1976), Kharkevich (1992), Gorodkov (1966). A map by Chikov (1983) was used as base map, corresponding completely with the area of main distribution of the weed. Places of sporadic distribution were determined according to the following sources: Hulten & Fries (1986), Chikov (1983), Kharkevich (1992), Tolmachev (1976), Gorodkov (1966). The zone of weediness was determined based on literature data. Criterion of its allocation is the indication of the weed as frequently being found in fields of the Central part of the Non-Chernozem and Chernozem zones (Zakharenko & Zakharenko, 2004), as a background species in fields of the Non-Chernozem zone (Spiridonov, 2004), as a main species in Nizhnii Novgorod Region (Tikhornova, 1937), as a main weed of grain crops, winter rye, and potato in Byelorussia (based on the work of Kozlovskaya & Simonovich (1966), Padenov & Samersov (1997) and Samersov et al. (2000)), as the most widespread weed in Lithuania (Monskvilaite & Shalna, 1972), as a pernicious weed of winter rye and most widespread weed of winter wheat in Moscow Region (based on the work of Blagoveshchenskii (1966) and Populovskaya (1936)). 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.
