Do you need a GCN survey or eDNA test in Somerset?
Somerset’s landscape of lowland farmland, wet grasslands, estate ponds, and river corridors provides excellent habitat for Great Crested Newts. Planning authorities often request surveys where developments may affect ponds or connected terrestrial habitats, including wet pastures and hedgerow networks.
A GCN assessment identifies suitable habitat, evaluates potential project risks, and determines whether eDNA testing or full presence/absence surveys are required. Early advice avoids seasonal delays and ensures compliance.
You may require a Great Crested Newt (GCN) or eDNA survey in Somerset if your project involves:
Development near farm ponds or balancing ponds around Taunton, Yeovil, or Bridgwater
Residential or commercial schemes impacting wet pasture or hedgerow networks
Landscaping affecting estate lakes, parkland ponds, or floodplain features
Brownfield or infill projects with retained waterbodies
Sites flagged as moderate or high GCN potential in ecological records
Construction scheduled during the April–June survey season
Early site screening ensures surveys are proportionate.
We deliver Great Crested Newt (GCN) surveys across Somerset, including Taunton, Yeovil, Bridgwater, Wells, Frome, and surrounding villages.

Why Planning Officers in Somerset Request GCN Assessments
In Somerset, local planning authorities may request Great Crested Newt (GCN) survey evidence where suitable habitats—such as ponds, wet ditches, watercourse margins, and surrounding terrestrial areas—are present, to ensure development proposals comply with wildlife legislation and national planning policy. Without timely and proportionate survey work, planning applications can face delays due to validation queries, additional planning conditions, or seasonal restrictions linked to key GCN activity periods. Such delays can disrupt project timelines and may lead to avoidable redesigns, emphasizing the importance of early, targeted GCN assessments.

FAQ - GCN Surveys in Somerset
What is eDNA testing for Great Crested Newts?
Environmental DNA (eDNA) testing involves collecting water samples from ponds, lakes, or other waterbodies and analysing them in a laboratory for traces of great crested newts. It allows ecologists to determine their presence or likely absence without repeated field visits.
Why might eDNA testing be needed in Somerset?
If your site contains, or is near, ponds, wetlands, or other suitable habitats, Somerset’s planning authorities often require evidence of great crested newts before approving development. eDNA testing provides a fast and non-invasive way to meet these requirements.
When is the best time to take eDNA samples?
The survey window is typically mid-April to the end of June, when newts are active and DNA is most detectable in water. Conducting sampling outside this period may result in unreliable results and affect planning submissions.
How reliable is eDNA testing compared to traditional surveys?
eDNA testing is highly sensitive and can detect even small populations of newts. While very effective, further surveys may sometimes be needed if multiple ponds are nearby or the site has high-quality habitat.
What happens if the eDNA test is positive?
A positive result confirms that great crested newts are present. Additional surveys, such as presence/absence or population assessments, may then be required to design mitigation measures and obtain any necessary wildlife licences before development proceeds.
How does eDNA testing support planning applications in Somerset?
Completing eDNA surveys early helps avoid seasonal delays and provides robust ecological evidence for planning authorities. This can reduce the likelihood of extra surveys, planning conditions, or changes being imposed by Somerset County Council or local district councils.
