Great Crested Newts – Have You Booked Your Survey?

  • 28 Feb 2019 by Editor

Great crested newts (GCNs) and their habitats are protected by European and British law.
Where GCNs are present, survey reports and mitigation plans are necessary to support planning applications and must be completed at the right time of year, ideally between mid-March until June.

To discuss your requirements or to book a survey, contact our experienced

Great Crested Newts

Do I Need a GCN Survey?

A survey must be undertaken if:

  • distribution and historical records suggest newts may be present.
  • a pond is located within 500 metres of the development.
  • the development site includes refuges (e.g. log piles or rubble), grassland, scrub, woodland or hedgerows.

GCNs may be present even if:

  • the site has been ploughed, soil stripped or had ponds filled in within the last 4 years.
  • the breeding pond was destroyed several years ago.
  • the pond is muddy, heavily shaded or vegetated.
  • the pond contains fish.
  • the pond is temporary.
