Date of creation:

27.09.2004

Scale:

1:20.000.000.

Accuracy of map:

Map was created using a map of gardens of the USSR with the scale 1: 20 000 000

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. Points represent recorded locations of the species; polygons represent area of possible distribution of the species.

Accuracy of classifier:

Polygons are based on literature sources, political boundaries and ecological description. Point data were obtained from literature sources and herbarium specimens.

Method of map production:

Historic agricultural statistics were reviewed for each agricultural region. The Former Soviet Union had 16 regions. The boundaries from the 1:4000000 map of arable lands were used to further refine crop distribution (Koroljeva et al., 2003). The following sources were used to determined the map area for this species: State list (1994, 2004), Vehov (1978), Hope (1990), and Koroljeva (2003). The main plantations are distributed throughout the Ukraine, on the Volga, Altaj, Nechernozem, Central and Central-Chernozem regions (Vinogradov, 1977). In the northern zone, early-ripening types of hop require 1700 growing degree days. (Aleksandrov, 1991). Isolated points were determined according to Tolmachaev (1976).
