Authors:

Biologist - O.E. Kravchenko,
GIS-specialist - I.A. Budrevskaya

Date of creation:

15.02.2005.

Scale:

1:20,000,000

Accuracy of map:

Map created using a map of natural scale 1:4 000,000 and 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 other, 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 literature of Shishkin (1936) and Buch et al. (1981). The abundance of the weed within the zone of weediness is equal to a score of 3 or more on vegetable cultures and in summer grains.

Method of map production:

Published literature was reviewed, including Atlases, monographs and papers. The A. australis map from Kharkevich (1991) was used as a prototype. It was supplemented with the data of Grossgeim (1962), Petrosyan et al. (2003) and the herbarium materials of the N.I. Vavilov Institute. Specifications were made according to the references listed below. The zone of weediness was allocated in the Far East on arable lands based on the literature of Shishkin (1936) and Buch et al. (1981). 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.
