Object description Download GIS-layers


Specialist-biologist - O.E. Kravchenko,
GIS-specialist - I.A. Budrevskaya.

Date of creation:



1:20 000 000.

Accuracy of map:

Map was created based on materials of map of natural scale 1:40 000 000-1:55 000 000 and on literature data.


"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 the species distribution, and the second where the weed is considered a serious pest. Points represent locations where sporadic occurrence has been reported. Russian Knapweed is a quarantine object, so based on the work of Moskalenko (2001) we consider it as a harmful object within the zone of main distribution in the limits of agricultural lands.

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 species map from Volkov (1935) was used as a prototype. It was supplemented with the data of Moskalenko (2001) from Russia. Adjustments were made according to the references from the list below, materials from the Herbarium of weed plants in VIR and the database edited by Petrosyan et al. (1993). 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.
