Great Crested Newt Survey Season Explained

Great crested newts are among the UK's most protected amphibians, and their presence can significantly affect development projects. If your proposed development is located near a pond or suitable terrestrial habitat, your Local Planning Authority may require a Great Crested Newt Survey before planning permission can be granted.

Understanding when surveys can be carried out is essential, as they are restricted to specific times of the year. Missing the survey season could delay your planning application by several months.

What Is a Great Crested Newt Survey?

A Great Crested Newt Survey is an ecological assessment used to determine whether great crested newts are present within or close to a proposed development site.

The survey helps establish whether a development could impact this protected species and whether mitigation measures or licensing may be required before work begins.

Great crested newts are protected under the Wildlife and Countryside Act 1981 (as amended) and the Conservation of Habitats and Species Regulations 2017. It is an offence to deliberately capture, injure, kill or disturb great crested newts, or damage or destroy their breeding sites or resting places.

For this reason, Local Planning Authorities often request survey evidence before determining planning applications.

When Is Great Crested Newt Survey Season?

The main survey season runs from mid-March to mid-June, when great crested newts return to ponds to breed.

This period provides ecologists with the best opportunity to determine whether newts are present and, if so, estimate the size of the population. While surveys can sometimes continue into late June under suitable weather conditions, the optimal survey window is generally between March and June.

The exact timing of surveys depends on several factors, including:

• Weather conditions

• Night-time temperatures

• Water temperature

• Rainfall

• The condition of the pond

Experienced ecologists will assess these factors before carrying out survey visits to ensure the results are reliable and compliant with current guidance.

Why Is Survey Timing So Important?

Unlike many ecological assessments, Great Crested Newt Surveys cannot usually be undertaken at any time of year. During autumn and winter, great crested newts spend much of their time on land, sheltering beneath logs, stones, vegetation and other natural features. As a result, they are extremely difficult to detect.

The breeding season provides the only reliable opportunity to survey ponds and establish whether great crested newts are using the site.

If this survey window is missed, developers may need to wait until the following spring before surveys can be completed, potentially delaying planning applications and construction programmes.

Why Might You Need a Great Crested Newt Survey?

Not every development requires a survey. However, a Great Crested Newt Survey may be recommended if:

• There are ponds within or close to the development site.

• Suitable terrestrial habitat surrounds the site.

• A Preliminary Ecological Appraisal (PEA) identifies potential habitat.

• The Local Planning Authority requests further ecological information.

• The development could impact breeding ponds or surrounding habitat.

Even if no pond is located directly on the site, nearby ponds within the surrounding landscape may still need to be considered.

How Are Great Crested Newt Surveys Carried Out?

The survey process usually begins with a Habitat Suitability Index (HSI) assessment, which evaluates whether nearby ponds are likely to support great crested newts. If suitable habitat is identified, additional presence or absence surveys may be required.

Survey methods can include:

• Torchlight surveys

• Bottle trapping

• Egg searches

• Netting

A combination of these methods is often used across multiple survey visits to maximise the likelihood of detecting great crested newts where they are present. The number of visits required depends on current survey guidance and the objectives of the assessment.

What Happens If Great Crested Newts Are Found?

Finding great crested newts does not necessarily mean a development cannot proceed.

Instead, the survey findings help inform the most appropriate way to protect the species while allowing development to continue where possible.

Depending on the project, this may include:

• Avoiding sensitive habitats.

• Adjusting the site layout.

• Creating replacement habitat.

• Installing exclusion fencing.

• Carrying out supervised vegetation clearance.

• Obtaining the appropriate mitigation licence where required.

By considering ecology early in the planning process, these measures can often be incorporated into the design with minimal disruption.

How Can You Avoid Planning Delays?

One of the biggest mistakes developers make is waiting until a planning application has been submitted before considering ecological surveys.

If great crested newt habitat is identified after submission, additional surveys may be requested, causing avoidable delays.

The best approach is to commission a Preliminary Ecological Appraisal (PEA) as early as possible. If further surveys are required, they can then be scheduled within the appropriate survey season, helping to keep your project on track.
