Scale:

1:20,000,000.

Accuracy of map:

Map is based on data from herbarium specimens and maps of scale 1:25,000,000-80,000,000.

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 japonicus is a species that occupies sandy seacoasts of the Far East. The species distribution area extends along the coast of the Pacific Ocean and includes sites in Kamchatsky, Okhotsky, Udsky, Ussuryjsky and the Sakhalinsky areas, as well as islands of the Russian Far East. Individual points located far from the seacoasts represent invasive habitats of the species and were therefore not included in the general distribution area. Materials used to create this map include published maps of species distribution (Kharkevitch, 1989; Hulten & Fries, 1986; Moesel, 1965), materials from the Vavilov Institute of Plant Industry (St. Petersburg, Russia), and herbarium materials from the Biological Soil Institute of the Far East Branch of the Russian Academy of Science (Vladivostok, Russia).
