Date of creation:

20.05.2005.

Scale:

1:20,000,000.

Accuracy of map:

Map was created using maps of natural scale 1:15,000,000-1:100,000,000 and information from state publications.

Projection:

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

Basic contents:

Vector map. Main distribution area is shown by polygons, while sporadic distribution is shown by points.

Accuracy of classifier:

Within the weed distribution area, zones of weediness are not shown because the Rumex crispus is mainly a ruderal rather than a segetal plant.

Mapping procedure:

The map was created following an analysis of public cartographical materials and state publications. The map by Hulten & Fries (1986) was used as a prototype, supplemented with maps of species distribution in Grossgeim (1945), Tolmachev (1976), Kharkevich (1989), and Krasnoborov & Malyshev (1992). The northern, southern, western and eastern boundaries of the distribution area were outlined in accordance with Hulten & Fries (1986) and further sepcified using Grossgeim (1945) (southern boundary), Tolmachev (1976) (northern boundary), Kharkevich (1989) (eastern and northern boundaries), and Krasnoborov & Malyshev (1992) (northern and southern boundaries). The sporadic distribution was determined using Hulten & Fries (1986), Grossgeim (1945), Tolmachev (1976), Kharkevich (1989), and Krasnoborov & Malyshev (1992).
