Map was created using maps of natural scale 1:5,000,000-1:80,000,000 and published data.Projection:

Vector map. Main distribution area is shown by polygons, while sporadic distribution is shown by points. Zone of weediness is shown by polygons.Accuracy of classifier:
Within the weed distribution area, zones of main and sporadic distribution and a zone of weediness are shown, where S. palustris is a pernicious weed.Mapping procedure:
Areas of main distribution, sporadic distribution and weediness were established following an analysis of published maps and literature. The distribution area of S. palustris is based on the map in Hulten & Fries (1986). The boundaries of the zone of weediness were established in accordance with Nikitin (1983) and Ulyanova (1998), were further specified in accordance with data on abundance and frequency of species occurrence taken from the below-mentioned references, and were adjusted in accordance with the boundaries of arable lands. According to Nikitin, S. palustris is a relatively resistant weed in all crops in the northern taiga zone and is sometimes quite abundant. Ulyanova included S. palustris in the list of main weeds of crops of the European former USSR. According to Ulyanova et al. (1992), S. palustris is a pernicious weed in the Novgorod and Vologda Regions characterized by 75-100% frequency of occurrence and 3-5 points of abundance.Sources of data:
