Exactness of map:

The map was created using maps of scale 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 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). 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 Kochia prostrata a germplasm collection (N.I. Vavilov All-Russian Institute of Plant Industry (VIR), St. Petersburg) and a published map of part of the distribution area (Ivanov et al., 1986) were used. The point locations of Kochia prostrata were mainly derived from species locations identified in the VIR germplasm collection. The general distribution area was mapped by generalizing published data to create a single polygon (green line). The polygon occupies the southern European part of the former USSR (mainly the steppe zone), the Crimea, the Caucasus, the south of Western and Eastern Siberia and all of Central Asia. When creating the distribution area borders, we took into account the biological and ecological preferences of the species and all available published data (Iljin, 1936; Goloskokov, 1960; Sergievskaja, 1964; Musaev, 1965; Ovchinnikov, 1978; Brezhnev & Korovina, 1980; Nikitin & Geldikhanov, 1988).
