Assessor(s): Tuniyev, B., Nilson, G., Agasyan, A., Orlov, N.L. & Tuniyev, S.
Reviewer(s): Cox, N.A. & Temple, H.J.
Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its mountain steppe habitat due to overgrazing and agricultural conversion.

Habitat and Ecology [top]

Habitat and Ecology:This is a mountain-steppe species that is almost always found around rocky outcrops in short grass steppe. It inhabits slopes of mountains, rocky outcrops and talus slopes, rocky-mountain steppes, humid steppe meadows, and banks of canyons that are overgrown with bush vegetation. It has been recorded from rural areas. In hot part of the summer it changes from diurnal activity to being active in the morning and evening hours. The species is viviparous, with litters of up to 10 young are born (Latifi, 1991). The period of activity before hibernation lasts from April - May to October.

Threats [top]

Major Threat(s): This species is threatened by the overgrazing of its habitat by domestic livestock (sheep). It is more generally threatened by the overall degradation of mountain habitats. An additional threat is the conversion of suitable habitat to intensive agricultural use at lower elevations.

Conservation Actions [top]

Conservation Actions: Populations are present within the grasslands of the Khosrov and Dilijan Reserve (Armenia).
