Smooth newts are common garden pond visitors whose welfare benefits from simple habitat improvements and are threatened by introduced fish in garden ponds.
Smooth newts in garden ponds with introduced fish experience high larval and egg mortality from predation. Adults migrating to and from ponds cross roads and garden barriers with associated mortality risk. Smooth newts exposed to garden chemicals through lawn and plant treatment accumulate toxins causing sub-lethal health effects. Animals caught in garden netting and fencing may die from desiccation or predation. Creating fish-free ponds provides safe breeding habitat that dramatically improves local smooth newt welfare and population health.
