Habitat and Ecology [top]

Habitat and Ecology:This species is generally found in rocky montane areas with sparse scrubby vegetation at elevations above 1,000m asl. Animals may occasionally be found at rocky sites within woodlands (Latifi, 1991; Baran and Atatur, 1998). It is an ovoviparous species; the female gives birth to between three and nine young (Baran and Atatur, 1998).The duration of pregnancy is 140 - 160 days. This species forms congregations during the winter (Nilson, pers. comm. 2008).

Threats [top]

Major Threat(s): In Turkey, this species overcollected for the pet trade, most particularly in the Aras River Valley. This species is particularly vulnerable to overexploitation because of its congregatory habits which make it easy to collect. Like all snakes and particularly vipers, this species is subject to local persecution. This species is also threatened by general development and overgrazing of its habitat.

Conservation Actions [top]

Conservation Actions: It is protected in the Khosrov Reserve in Armenia. It was included into the Red Data Books of the USSR (1984) and Armenia (1987) as a narrow-endemic species. This species is found in Egridagi National Park in Turkey. There is a need to effectively regulate the collection of this species and monitor populations.
