This silver commemorative coin depicting Armenian Viper has been issued by the Central Bank of Armenia under the International Program "Wild World of Caucasus". The Program includes animals that are protected under the Red Book of Armenia. Armenian Viper dwells on stony steep slopes of the mountains and in canyons covered by thinly growing oaken forests and other woods and shrubs at the height of 1100-2300 meters above sea level. Presently, the areas of habitation of Armenian Viper have considerably changed due to agricultural reclamation of lands. The number of these species ranges from 4 to 6 per hectare on average. The total number reaches 1000-1500 species.
