Exactness of map:

The map was created using maps of scale 1:25,000,000-1:40,000,000.

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 polygons and points. Locations of species are represented by points; area of possible distribution of species is represented by polygons.

Exactness of classifier:

Light-colored points represent species locations referenced in published sources. Dark-colored points represent locations of the species reported in the VIR database (N.I. Vavilov All-Russian Research Institute of Plant Industry) and the BIN database (Komarov Botanical Institute). Polygons are based on published sources, herbarium samples, political boundaries and ecological descriptions.

Method of map construction:

In order to construct the distribution area of Bromopsis ornans, a published map of species distribution areas (Harkevich, 1985), herbaria data from the N.I. Vavilov All-Russian Institute of Plant Industry (VIR) in St. Petersburg and herbaria data from the Komarov Botanical Institute (BIN) were used. Endemic in the Far East. Final species distribution area is represented by two polygons (green line) and separate points, which correspond to published data on species distribution (Tzvelev, 1976; Brezhnev and Korovina, 1980; Harkevich, 1982; Harkevich, 1985; Malyshev and Peshkova, 1990). The points, which were not used to create the main species distribution area, represent single sites at which the species has been found. The distribution area takes into account the ecological preferences of the species.
