Habitat and Ecology [top]

Habitat and Ecology:This species is associated with alpine meadows or alpine steppe habitat. The diet generally consists of crickets (orthoptera) and lizards. It is a ovoviviparous species.

Threats [top]

Major Threat(s): The species has a restricted habitat type which is threatened by overgrazing by domestic livestock in some areas (Göran Nilson pers. comm., September, 2008). and by the removal of the fertile alpine topsoil for commercial horticultural use in others (Mozafar Sharifi pers. comm., September 2008). A small number of animals have been reported in the international pet trade (Göran Nilson pers. comm., September, 2008).

Conservation Actions [top]

Conservation Actions: It is present in the Lar River Valley Protected Area (Central Province). There is a need to prevent overgrazing and better regulate the collection of topsoil within the limited range of this species.
