1:20 000 000Accuracy of map:
Map was created based on materials of maps of natural scale 1:4 000 000 - 1:25 000 000 and on literature data.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. Points represent locations where sporadic occurrence has been reported. The zone of weediness was allocated in the Far East on arable lands based on the following literary data: Shishkin (1936), Nikitin (1985), Ulyanova (1998). In the zone of weediness the plant litters 50% of crops of soya, potato, and grain crops (except for rice).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 map of Artemisia desertorum from Kharkevitch (1992) was used as a prototype. It was supplemented with the data of Krasnoborov (1997), the herbarium of weed plants at VIR (N.I. Vavilov Institute) and the database cited by Petrosyan et al. (2003). Specifications were determined according to references from the below list. The zone of weediness was allocated in the Far East on arable lands according to the following literary data: Shishkin (1936), Nikitin (1985), Ulyanova (1998). From the end of the 20th century the weed became the most widespread weed of grain crops, soya, and other vegetable cultures.Reference citations:
