Overview
Who is Eastern steppe viper
The eastern steppe viper (Vipera renardi), also called Renard's viper, is a venomous member of the viper family in the ursinii–renardi complex. It ranges from south-eastern Europe into Central Asia; IUCN also includes Transcaucasian populations in Armenia, Azerbaijan, and Georgia. In Georgia it occurs on the Javakheti and Erusheti plateaus (often treated as V. r. eriwanensis / southern steppe viper) and in the east around the Shiraki Plateau and Dedoplistskaro (Shemakha group / kakhetiensis). It is relatively small (about 40–60 cm), with a dark dorsal zigzag, and prefers open steppe habitats. The European regional IUCN assessment lists it as Vulnerable due to habitat loss.

Identification
How to identify Eastern steppe viper
The eastern steppe viper is a small venomous steppe species. Size, a dorsal zigzag, and open steppe habitat are the main cues — and it is rare in Georgia.
- 01
Relatively small — length roughly 40–60 cm.
- 02
The pupil is vertical; scales are keeled; the head is broad.
- 03
A dark zigzag or row of blotches on a pale dorsum.
- 04
In Georgia it is tied to the Javakheti–Erusheti plateaus and Kakheti steppe.
- 05
Smaller and more steppe-bound than the Levantine viper; lacks the nose-horn of V. ammodytes.
Biology
Diet, behavior, and conservation
Diet
Members of the ursinii–renardi complex often feed on orthopterans — grasshoppers and related insects — as well as lizards and small rodents. Juveniles hunt smaller invertebrates and lizards. It hunts by ambush and subdues prey with venom.
Behavior
Active in the warm season — in Georgia and Azerbaijan roughly from April to early October. In spring and autumn it is often diurnal; in summer heat it seeks shade and scrub. It hibernates in crevices and under stones. It is ovoviviparous: pregnancy lasts about three months; young are born in July– August (sometimes up to 10–17 individuals).
Conservation
Listed as Vulnerable in the European regional IUCN assessment — over 30% habitat loss across the last three generations and ongoing fragmentation. The main threat is conversion of steppe and meadows to intensive agriculture and overgrazing. It is rare in Georgia; eastern populations were reconfirmed after a 75-year gap. It benefits ecosystems by regulating insects and rodents.
Questions
Frequently asked questions
Short answers to the most important questions about Eastern steppe viper.
It is venomous, though danger is rated moderate — milder than the Levantine or nose-horned viper. Immediate medical attention is still required; the snake bites mainly when it feels threatened.
Rarely — in Samtskhe–Javakheti (Javakheti and Erusheti plateaus) and Kakheti (Shiraki Plateau, around Dedoplistskaro and Khornabuji). Open steppe and foothill habitats are key.
The steppe viper is smaller (about 40–60 cm) and prefers open steppe. The Levantine viper is large, egg-laying, and lives in dry eastern lowlands. The nose-horned viper has a snout horn and is linked to the Lesser Caucasus highlands.
It is ovoviviparous — young are born in July–August; pregnancy lasts about three months.
Intensive conversion and overgrazing of steppe and meadows destroy its habitat and fragment the range. The European IUCN assessment lists it as Vulnerable; Georgian populations are small and scarce.
