Basic contents:

The map is a vector file consisting of 1 basic and 2 subject layers. The species range is represented by a polygon and dots.

Accuracy of the qualifier:

The dots represent information on the species localities: 1 - reliable data from herbarium and published sources; the polygon (1) - generalized information on the species distribution from published sources and herbarium specimens.

Method of the map construction:

The data from the herbarium materials of LE and published data (Bobrov, 1945, 1987; Brezhnev, Korovina, 1980) were used for constructing the range of Trifolium borystenicum. The range consists of one polygon and dots corresponding to the species localities according to LE herbarium. The range stretches from the western borders of the former USSR to northwestern Kazakhstan in the east, to cover the forest-steppe zone of East European Plain. The dots outside the polygon reflect solitary localities of the species.
