Great Crested Newts (Triturus cristatus) are the largest native species of newt found in Britain, growing up to 17cm long and living for as long as 27 years.

During breeding season, females lay up to 300 eggs, each individually wrapped in its own leaf.

In addition to the large crest on breeding males, Great Crested Newts can be identified by their size, their warty skin, and the yellow stripes on their toes!

Types of Survey

Habitat Suitability Index (HSI) – Waterbodies are assessed for their suitability as habitat for Great Crested Newt.  This is done by assessing ten attributes including shading, presence of fish and coverage of aquatic plants.

Environmental DNA (eDNA) – In order to assess presence or likely absence of Great Crested Newt in a waterbody, water samples are taken and sent to an accredited laboratory to check for the presence of Great Crested Newt DNA.

Trapping – Bottle traps are set up at night, and collected early the following morning. Any animals caught in the traps are counted and released back into their habitat.

Torch surveys – High powered torches are used to search for Great Crested Newt.

Egg Searching – Eggs are searched for in the vegetation to confirm whether Great Crested Newt is breeding in a waterbody.

Netting – A specialist net can be used to capture Great Crested Newt individuals.
