Authors:

Object specialist S.Yu.Larina,
GIS-specialist I.A.Budrevskaya.

Data of creation:

22.12.2003.

Scale:

1:20 000 000.

Accuracy of map:

Created using maps of natural scale 1:5 000 000 - 1:80 000 000.

Projection:

"Alber's Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

Vector map. Area of distribution is shown by polygons (basic distribution) and by points (sporadic distribution). Zones of harmfulness are shown by polygons.

Accuracy of the 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 areas of distribution and harmfulness of Chenopodium polyspermum were established according to an analysis of open-published maps and literature. The areas of distribution were determined from the following source: (Hulten & Fries, 1986). Sites of sporadic distribution in the territory of Western Siberia were determined according to: (Hulten & Fries, 1986), (Krasnoborov, 1992) and were included in the area of basic distribution. Distribution was also expanded to the territories of the Baltic States and the adjacent regions of North-Western Russia according to: (Nikitin, 1983). Areas of harmfulness are established according to: (Korovina, 1982), (Rodionova, 2001) and adjusted using the boundaries of the Map of Arable Lands. In addition to the data of Hulten & Fries (1986), the sites of sporadic distribution of Chenopodium polyspermum are depicted in the Caucasus according to: (Grossgeim, 1945); and in Siberia according to: (Krasnoborov, 1992) and (Pronkina & Shcherbina, 1994).

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 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
