Overgrowing forest as a possible cause for the local extinction of Vipera aspis in the northern Swiss Jura mountains

, : Overgrowing forest as a possible cause for the local extinction of Vipera aspis in the northern Swiss Jura mountains. Amphibia Reptilia 20(1): 25-34

In the northern Swiss Jura mountains, the asp viper (Vipera aspis) was common until the 1940s. During the past 50 years many local populations have become extinct and today it is considered to be a threatened species. A comparison was made between habitat characteristics of localities with extant viper populations with those of localities where the species has become extinct.
