Scale:

1:20,000,000.

Accuracy of map:

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

The projection:

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

Basic contents:

Vector maps: Areas of continuous cultivation are represented by polygons.

Accuracy of qualifier:

Maps were created using generalized regional information about species distribution from published sources.

Mapping procedure:

The distribution area map was created using published data (Tulupnikov, 1960; State, 1994, 2004). Distribution area within the former USSR covers the Volga regions (Saratov, Samara, Volgograd, Orenburg, Rostov), Kazahstan, Western Siberia, the Northern Caucasus, Transcaucasia (Azerbaijan), and Dagestan (Samsonov, 1967; Vehov, 1978; Dorofeev & Korovina, 1979; Bujukli, 1983; Guzhin et al., 1984). The northern border of crop distribution follows the middle stream of the Danube, the steppe of the Ukraine, the upper stream of the Don, the Upper Volga (including southern regions of Nizhniy Novgorod), the Kama river regions, and the northern forest-steppe of Western Siberia to the upper stream of the Yenisei (Kuptsov, 1975; Dorofeev & Korovina, 1979). Main crops in Siberia are grown in the Omsk and Novosibirsk regions and in Altai krai, where the sum of active temperatures is above 1900°C (Savitskaja et al., 1987).
