Date of creation:

Scale:

1:20,000,000.

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 the species are represented by points, while the areas of possible distribution of the species are 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 (the Komorov Institute of Botany). Polygons are based on published sources, herbarium samples, political boundaries and ecological descriptions.

Method of map construction:

The species distribution area was constructed using published maps and materials from the Vavilov Institute and the Komorov Institute of Botany. Literature consulted includes the map of Onobrychis arenaria distribution from Meusel (1965), Hulten & Fries (1986), Sinskaya (1948) and the VIR and BIN databases. Points not included in the polygon represent invasion by the species. The final species distribution area also takes into account the ecological preferences of the species.

Sources of data:
