The Alpine newt (Ichthyosaura alpestris) is a non-native amphibian species in the UK, introduced through the pet trade and accidental releases. Native to central and southern Europe, this newt has established small populations in parts of the UK. It inhabits ponds, lakes, and other freshwater habitats, particularly those with aquatic vegetation, where it feeds on invertebrates. While its ecological impact in the UK is not fully understood, it may compete with native amphibians for resources and has the potential to spread pathogens like chytrid fungus.
