Accuracy of map:

Created using maps of scale 1:12,000,000-1:40,000,000, as well as collection site location data from herbaria and databases of the Department of Introduction and Department of Genetic Resources of Perennial Fodder Crops, N.I. Vavilov Institute.


"Alber.s Equal Area Conic for Russia " 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

Vector map. The area of species is represented by polygons and points.

Accuracy of classifier:

Point data were obtained from literature sources and herbarium specimens (N.I. Vavilov Istitute); (Savkina et al, 1982); (Kharkevich, 1985); (Malyshev & Peshkova, 1990); (Malyshev & Peshkova, 1979). Polygons are based on literature sources, herbarium samples, and field surveys by the authors.

Method of map production:

Published literature was reviewed, including Atlases, monographs and papers. Occurrence data were obtained from herbarium specimens, floras, monographs and papers. Data were then compiled through scanning and geo-referencing to develop a composite vector map. The biologist, together with the GIS specialist, drew a new plant distribution area based on compiled data.
