Great Crested Newt Fact File

Scientific Name: Triturus cristatus
Conservation Status: Protected (Habitats Directive, UK Biodiversity Action Plan Priority Species)

The Great Crested Newt, often called the “warty newt,” is one of the UK’s most charismatic amphibians. Recognizable by its dramatic crest and striking coloration, this species can be a fascinating addition to your garden pond’s ecosystem.

Habitat

Great Crested Newts thrive in unpolluted, still freshwater habitats such as ponds, marshes, and ditches. They prefer ponds with abundant aquatic vegetation, which provides shelter and breeding grounds. If you have a garden pond, planting native aquatic plants and creating gentle, sloping edges can make it more suitable for these newts. Surrounding areas, like wildflower borders, woodpiles, and hedgerows, offer essential terrestrial shelter for foraging and hibernation.

For help finding the right native aquatic plants, visit Aqua Eden. We offer a wide selection of plants ideal for creating a newt-friendly environment.

Lifecycle

The lifecycle begins in early spring (March-May), when adults return to ponds to breed. Females lay eggs individually, wrapping each in leaves or aquatic plants. Larvae hatch in 2-4 weeks and develop into juveniles (known as efts) by late summer, leaving the water by autumn. Adults spend most of their lives on land, returning to water only to breed.

Size and Lifespan

Adults typically measure 12-17 cm in length, with males slightly larger than females. In the wild, Great Crested Newts can live up to 14 years, though 6-10 years is more common.

Conservation Status

This species faces threats from habitat loss, pollution, and invasive species. It is legally protected under UK and European law, making it illegal to capture, harm, or disturb them or their habitats.

When to See

Great Crested Newts are most visible during their breeding season (March to June). Look for them in your pond during twilight or night, when they’re most active.

How to Identify

Males boast a jagged, sail-like crest during breeding season and a vibrant orange belly speckled with black spots. Females are less vivid but share the belly pattern. Both sexes have warty, dark brown to black skin, providing excellent camouflage on land.

How to Adapt Your Garden Pond

To attract and protect Great Crested Newts, consider the following:

• Plant native aquatic vegetation such as water forget-me-not and ranunculus aquatica to provide shelter and egg-laying sites.
• Avoid using fish in your pond, as they can prey on newt larvae.
• Create a variety of depths with shallow areas for warmth and deeper zones for overwintering.
• Provide nearby shelter like log piles, rockeries, and dense vegetation for foraging and hibernation.
• Keep your pond chemical-free to maintain a healthy environment for newts and other wildlife.
