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

Data of creation:

29.10.2003.

Scale:

1:20 000 000.

Accuracy of the map:

It is created on materials of maps of natural scale 1:10 000 000-1:80 000 000 and on literature data.

Projection:

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

Basic contents:

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

Accuracy of the classifier:

The distribution of the species is divided into zones of basic distribution, sporadic distribution, and harmful area. The zones of weediness are shown - established by criteria of occurence (50% of fields where this species is found) and abundance, expressed as projective cover of this species in the field (more than 15 % to the field area (Tanskii et al., 1998).

Procedure of map drawing:

The zones of distribution and injury are allocated by results of the analysis of the cartographical materials published in an open seal and the literary data. For basis for construction of an area maps of distribution of Tussilago farfara have been taken from atlas Hulten E., Fries M. (1986) and from "The Atlas of areas and resources of herbs" (1976). Specifications and additions are made on the following materials "Flora of Siberia" (1997) and also on materials of the publications named below. Points of sporadic distribution are added on materials of herbarium AE? and "Florae of the USSR" (1964). The zone of nocuity is allocated according to the literary data. It settles down in repartitions of territory of agricultural lands in a wood zone. Coltsfoot is a malicious weed in a forest zone, where it litters crops different (everything) cultures according to academician A.I.Maltsev (1937), V.V.Nikitin (1983), T.N. Ulyanova (1988) and others. The plant has littered of all cultures in a zone of a southern taiga on the humidified places with an abundance 3 (4) points. Here the plant has littered 12-17 % of fields. Less often it meets in a zone of northern taiga and wide-deciduous forests (Shlyakova, 1982). 1,5 kgs of fresh rhizomes have been found from one square meter of the littered field. On rhizomes 2596 kidneys were totaled (Kott, 1955).
