Date of creation:
21.02.2008.Scale:
1:20 000 000.Accuracy of the map:
It is based on materials of the map with scale 1:33 000 000, using the information taken from literature.Projection:
"Alber's Equal Conica for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.Basic content:
Vector map, which consists of two thematic layers. Area of distribution and zone of damage are shown by polygons.Accuracy of the classifier:
Within the limits of distribution, the zone of low damage has been allocated where insect density reaches 1-2 or more individuals per sq.m in favorable conditions (plow land of seacoasts and lakeshores, alkali soils).Method for map production:
A map of the Steppe Mole Cricket distribution is drawn on the basis of published data (Zhantiev, 1991; Fedorova et al., 1991; Zhantiev et al., 2003). The northern border of area runs across Ukraine from Moldova to the north of Rostov Region; western and southern borders coincides with frontiers of the former USSR; eastern border runs across Rostov Region, Stavropol Territory to Caspian Sea; the area includes the south of Turkmenistan, excluding the deserts and mountain territories. Zone of low damage coincides with arable land distribution (Koroleva et al., 2003) in the area limit of G. stepposa.Reference citations:
