Authors:

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

Date of creation:

15.09.2004.

Scale:

1:20 000 000.

Accuracy of map:

Map was created based on maps of natural scale 1:10 000 000 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 following sources were used to determine the areas of sporadic distribution: Kharkevich (1992), Petrosyan et al. (2003). Within the weed area there is no data on the decrease in quality and quantity of crops and therefore the zone of weediness was not allocated. In the literature there has been some mention of some rare cases of weediness of Argyi Wormwood among agricultural lands (Ulyanova, 1985, 1998) but they do not specify obvious zone of weediness.

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 A. argyi map taken from Kharkevitch (1992) served as the prototype for this map. Adjustments were made according to the references below and also materials from the database of Petrosyan et al. (2003). In the territory of the former USSR the species occurs in the south of the Far East, i.e., in Primorskii Territory and Amur Region (Ussuri, Nizhnyaya Zeya, and Bureya districts). The area of distribution of the species is shown by dots according to data of Kharkevitch (1992). The majority of authors demonstrate that the Argyi Wormwood does not litter crops or insignificantly litters them and this is presented by the following sources: Vorob'ev et al. (1966), Buch et al. (1981), Kharkevitch (1992), Shishkin (1936), Nikitin (1983). Therefore a zone of weediness was not allocated on the map. 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.
