Scale:

1:20,000,000.

Accuracy of map:

Created based on materials of maps of scale 1:12,000,000.

Projection:

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

Basic contents:

Vector map. Area of species distribution is shown by polygons, actual location occurrence in shown by points.

Accuracy of classifier:

Point data were obtained from literature sources and herbarium specimens. 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 (Shelyak-Sosonko, 1977). The area of the species was determined for the lower sites on the coast of the Azov and the Black seas occupied by shelly-sandy salinas. Data were then compiled through scanning and geo-referencing to develop a composite vector map. The biologist and GIS specialist drew a new plant distribution area based on compiled data.
