Date of creation:

4.12.2005

Scale:

1:20,000,000.

Exactness of map:

The map was created using maps of scale 1:10,000,000-1:80,000,000.

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 the species are represented by points, while the area of possible distribution of the species is represented by polygons.

Exactness of classifier:

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

Method of map construction:

To construct the distribution area of Poa alpine, published maps of species distribution (Grossheim, 1939; Tolmachev, 1974; Shelyag-Sosonko, 1977; Harkevich, 1985; Hulten & Fries, 1986) and herbaria data from the N.I. Vavilov All-Russian Institute of Plant Industry (VIR) (St. Petersburg) and the Komarov Botanical Institute (BIN) were used. The final species distribution area contains 10 polygons (green line) and separate points and corresponds to published data on species distribution (Tzvelev, 1976; Malyshev & Peshkova, 1990; Pavlov, 1956; Fedorov, 1974). The points, which were not included in the polygons, represent single sites of the species. The distribution area borders take into account the ecological preferences of the species.
