Scale:

1:20,000,000.

Exactness of map:

The map was created using herbaria data.

The projection:

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

Basic contents:

Map is a vector file consisting of a polygon and points. Locations of species are represented by points; area of possible distribution of species is represented by a polygon.

Exactness of classifier:

Dark-colored points represent locations of the species reported in the VIR database (N.I. Vavilov All-Russian Research Institute of Plant Industry) and BIN database (the Komorov Institute of Botany).

Method of map construction:

In order to construct the distribution area of Bromopsis ircutensis, the herbaria data from the N.I. Vavilov All-Russian Institute of Plant Industry (VIR) in St. Petersburg and the Komarov Botanical Institute (BIN) in St. Petersburg were used. Final species distribution area is represented by one polygon (green line) and corresponds to published data on species distribution (Tzvelev, 1976). The distribution are borders take into account the ecological preferences of the species.
