British Great Crested Newt

The Great Crested Newt (Triturus cristatus) is also known as the Northern Crested Newt and Warty Newt. Great crested newts are widespread, but extremely local, in mainland Britain, however, they are not found in Ireland. The Great Crested Newt can also be found across northern Europe, from France in the west, to the Urals in the east.

The Great Crested Newt is one of only three amphibians which are protected by the Uk Biodiversity Action Plan. The Great Crested Newt is one of three newts found in the British Isles, along with the Smooth Newt and the Palmate Newt and is the biggest and least common of the three.

Great crested newts have dark grey-brown backs and flanks and are covered with darker coloured spots so that they appear almost black in colour.

Their undersides are either yellow or orange-coloured and are covered in large black blotches.

Male crested newts can be distinguished from females by the presence of a jagged crest that runs along their backs, dipping at the rear of the abdomen to a smoother-edged crest above and below the tail.

In the UK, great crested newts may grow up to 17 centimetres long (body and tail). Great crested newts are the largest species of newt found in Britain.

Great crested newts often return to the same breeding site. After a courtship display great crested newts mate and breed in ponds and pools. The female lays 200 - 300 eggs on aquatic plants. Once juveniles have emerged from ponds it can take up to 4 years to reach sexual maturity, during which time the juvenile newts are primarily terrestrial. It is possible for the Great crested newt to reach an age of 27 years.

Outside of the breeding season, adult and juvenile newts are found in suitable terrestrial habitat where they seek shelter under rocks, logs and other suitable refuge.

The Great crested newts diet consists primarily of invertebrates including insects, worms, water snails, larvae and sometimes tadpoles.

In the United Kingdom, habitat of the Great Crested Newt has diminished due to land development pressure from population growth and agricultural expansion; for example, it is considered eliminated from its prior range at the Portlethen Moss Nature Reserve in Scotland.

The Great Crested Newt is a protected species in other jurisdictions as well, notably in Germany, where a planned extension to an Autobahn in Hesse may come to naught as a result.
