Great Crested Newt Survey: Protected Species Surveys

What is a Great Crested Newt Survey?

A Great Crested Newt Survey is a protected species survey method which can be undertaken to detect the presence or absence of Great Crested Newts on or close to a development site. Some traditional survey methods for detecting whether newts are present include torching and pitfall traps and bottle trapping. EDNA Surveys are a newer survey method which involves the analysis of water samples to determine whether there is environmental DNA from Great Crested Newts present in an environment, such as a pond or other body of water.

When and Why are Great Crested Newt Surveys Required?

Great Crested Newts are European a protected species, it is therefore, an offence to intentionally harm or destroy this type of species, or its habitat. Surveys for great crested newts are usually required for planning applications for projects which may affect great crested newt populations. Planning applications would then be assessed by local planning authorities.

This type of survey should always be carried out by a qualified and experienced Ecologist with a Natural England Great Crested Newt Licence.

A survey for great crested newts should be undertaken if there are suggestions that great crested newts will be impacted by the planned development. This species is likely to be present in areas where there is a freshwater pond or other aquatic habitats within 250 meters of the development site, or if the site includes woodland, hedgerows, refuges, scrub, or grassland, and a survey will therefore be required.

If newts are unlikely to be present within an area, or if the planned development would have no impact on the GCN population, a survey may not be needed.

Great Crested Newt Survey Methodology

There are different types of great crested new surveys, including traditional methods and the newer EDNA surveys. An EDNA survey will detect the presence of great crested newts within a body of water; however, if great crested newts are detected, a full survey using traditional methods will be required to determine population sizes.

Traditional great crested newt survey methods include:

  • Pitfall traps
  • Netting
  • Bottle trapping
  • Funnel trapping
  • Egg searches in aquatic vegetation

In order to prove the absence of great crested newts on a site, four survey visits will be required. If the species are found to be present on the site, six surveys will be needed to show the number of newts present.

Survey work is limited to specific times of the year. Surveys should be undertaken during breeding season from mid March to mid June. EDNA surveys can take place from mid April to mid June. If surveys are carried out outside of the recommended timings, the results may not be accurate and will not be accepted by Natural England for a planning application.

Great Crested Newt District Licensing Scheme

Many planning authorities now offer district-wide licensing schemes which allows developers to make a conservation payment to cover the restoration or creation of ponds in locations away from the development site. This scheme is an easier and more efficient method of applying for a a great crested newt mitigation license and means that developers are not required to  carry out their own great crested newt surveys or mitigation work. In some cases eDNA surveys will be required to determine GCN presence/ absence and confirm eligibility for the scheme.

How Can Collington Winter Assist?

Collington Winter are an experienced team of Ecologists, providing great crested newt surveys to developers on all types of projects. We offer both traditional surveys as well as GCN EDNA surveys.

Laboratory turnaround on eDNA samples is typically 10 working days, but can be expedited under a FastTrack scheme where necessary.

If great crested newts are discovered on a proposed development site, we can also assist by carrying out mitigation and compensation methods.

Our Ecology Director, Olivia Collington, holds a Natural England Great Crested Newt licence, and has worked with protected species across the UK, undertaking field surveys and writing scientific, reports for submission at planning.

We adopt a pragmatic approach to all sites, working with clients to find solutions and develop relationships. With current offices located in Greater Manchester and Dumfries, the team are well served to work nationwide. Over the years, we have built strong relationships with key stakeholders across the UK.

Please get in touch with our Ecology Director Olivia Collington ( for more information on GCN surveys and mitigation. We also provide ecological appraisal and assessment services.
