Scale:

1:20,000,000.

Accuracy of map:

Map was created using herbarium specimens and maps of scale 1:30,000,000-80,000,000.

The projection:

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

Basic content:

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

Accuracy of qualifier:

Light-colored points represent species locations referenced in published sources. Dark-colored points represent locations from which herbarium samples were taken. Polygon is based on generalized information from published sources, herbarium specimens, political boundaries and ecological descriptions.

Method of map construction:

Lathyrus maritimus is distributed along seacoasts and lakes in countries with moderate and moderate-cold climates. The species grows on coastal sand-and-shingle spits and on coastal banks. Within the former USSR, the species distribution area is shown by a polygon, a narrow strip that extends lengthways along the coasts of seas and large lakes (especially Ladoga) in the northwest. In order to map the species distribution area, data from the Vavilov All-Russian Institute of Plant industry (St. Petersburg, Russia) and the Moscow State University (Russia) herbaria and published maps of species distribution (Arctic Flora of the USSR, 1986; Hulten & Fries, 1986; Mozel, 1965) were used. The points not included in the general distribution area represent individual species locations outside the natural distribution area.
