1:20,000,000.Accuracy of map:
Map was created using maps of natural scale 1:8,000,000-1:55,000,000 and published data.Projection:
"Alber's Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.Main content:
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:
The distribution area of the species is divided into zones of main distribution, sporadic distribution, and weediness.Mapping procedure:
Zones of distribution and weediness were allocated following an analysis of public cartographical materials and published literature. The Lactuca sibirica distribution map by Hulten & Fries (1986) serves as a model. It was supplemented with data from Kharkevich (1992), Krasnoborov (1997) and Tolmachev (1977). The distribution area was further specified using the references listed below and the materials of the VIR Herbarium of weed plants. Lactuca sibirica grows mainly in forest zones. The northern and southern borders of the distribution area in the European region were drawn in forest zone in accordance with Hulten & Fries (1986). In the northeastern European region, the border was modified in accordance with the data of Tolmachev (1977). In the Far East, the species is distributed throughout the forest and forest-steppe zones (probably because of the man-made ecosystems there) according to Hulten & Fries (1986) and Kharkevich (1992). In Siberia, the species is also distributed throughout the forest zone according Krasnoborov (1997). Only occasionally is the southern border located in the forest-steppe zone. The area of sporadic distribution of Lactuca sibirica is located in forest-tundra at high latitudes in Siberia and the Far East. There is no published data on the weediness of Lactuca sibirica. Hence, we did not allocate a zone of weediness on the map. The unique recent report about the species as a weed belongs to Nikitin (1983). The species can be considered a potential weed only.Sources of data:
