The great crested newt is legally protected and the subject of major conservation programmes that also benefit other wildlife.
Great crested newts face welfare threats from pond drainage and filling which destroys breeding habitat. Road mortality during spring and autumn migration between ponds and terrestrial habitat is significant. Development that fragments terrestrial habitat isolates populations. Pesticide use in agricultural areas around ponds reduces aquatic invertebrate prey. Climate-driven drought can desiccate small ponds during breeding season.
