1:20 000 000.

Accuracy of map:

It is created on information taken from the open published literature and maps of scale 1: 40 000 000; 1:45 000 000 and 1:17000000.

Basic content:

It is a vector map consisting of 2 layers. Area and zone of pest damage are shown by polygons.

Accuracy of the classifier:

The zone of high pest damage is indicated within the limits of the area where outbreaks occur periodically; density of Afghan Vole population can run up to 1,000 individuals per hectare. As a consequence, practically total extermination of pasture vegetation happens in these localities. The Afghan Vole has no economic significance on the rest part of the area in view of its low numbers.

Method of map production:

Cartographical data (Bobrinskii et al., 1965; Polyakov, 1968; Flint et al., 1970) as well as text records (Vinogradov & Ivanov, 1945; Nurgeldyev, 1956; 1971; Davydov, 1958; Golenishchev, 2000-2002) were used when map preparation. The south boundary of the area coincides with the state boundaries of Turkmenistan, Uzbekistan, and Tajikistan, where these three countries are contiguous with Iran and Afghanistan. Mountain territories were excluded from the area since the Afghan Vole inhabits regions below altitude 1700 m. The borders of the pest high damage zone are determined according to the map taken from the publication of I.Ya. Polyakov (1968). However, the latest data testify that this zone was reduced, because the significance of the Afghan Vole as a pest of crops in Tajikistan lowered in a result of irrigation agriculture widening and cattle overgrazing (Davydov, 1988, 1992). Correction of the area and high pest damage zone are carried out according to the territories of the largest grain crops distribution (Koroleva et al., 2003) and USSR vegetetion map (Chikov, 1983). The zone of subtropic submontane steppes is used as a landscape indicator since ecotopes of the Afghan Vole are confined to this zone.
