Abstract

The snake Vipera aspis aspis used to be quite common In the Swiss Jura mountains in the beginning of this century. However, during the last 50 - 60 years many populations became extinct. Different factors might be responsible for the decline of this species (e.g. the loss of small structures such as hedges and stonewalls in the landscape due to intensive agitculture, the active killing by human beings, the collecting of specimen for museums or pet holders, an increasing isolation of the populations by road or railway constructions and the loss of connecting populations).
