The Italian crested newt is endangered in its forest habitat throughout its area of distribution in the southern Alps. The decline in this species of amphibian is attributable to the destruction of land and water-based habitats as well as water pollution.
The Italian crested newt prefers large, still spawning ponds with gentle banks and landing areas, which are more than a metre deep and free of fish.
