Do you need a GCN survey or eDNA test in Sussex?
Sussex includes a diverse range of habitats, from chalk downland ponds and clay lowlands to wooded estates, river valleys, and coastal farmland. These landscapes can provide suitable breeding and terrestrial habitat for Great Crested Newts, meaning planning authorities often require ecological evidence where development may impact ponds or associated habitats.
A GCN assessment helps determine habitat suitability, assesses potential risks, and confirms whether eDNA testing or traditional survey methods are required. Early engagement reduces uncertainty and helps prevent delays linked to seasonal survey constraints.
You may require a Great Crested Newt (GCN) or eDNA survey in Sussex if your project involves:
Development near chalk or clay-lined ponds on the South Downs or Weald
Residential extensions or infill sites in villages around Lewes or Haywards Heath
Farm diversification or agricultural works near historic field ponds in West Sussex
Infrastructure or drainage works close to river valleys such as the Arun or Ouse
Landscaping proposals affecting estate ponds or wet woodland margins
Sites identified as having GCN potential during planning screening or ecological appraisal
Confirming survey needs early is particularly important in Sussex due to varied geology and habitat connectivity.
We carry out Great Crested Newt (GCN) surveys across East Sussex and West Sussex, including Brighton and Hove, Crawley, Horsham, Chichester, Lewes, Eastbourne, Worthing, and surrounding rural areas.
Why Planning Officers in Sussex Request GCN Assessments
In Sussex, 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 Sussex
What is eDNA testing for Great Crested Newts?
eDNA (environmental DNA) testing involves collecting water samples from ponds or waterbodies and analysing them in a laboratory for traces of great crested newt DNA. This method provides evidence of newt presence or likely absence without the need for repeated traditional survey visits.
Why might I need eDNA testing in Sussex?
If your site contains, or is near, a pond or suitable newt habitat, local planning authorities often require evidence of great crested newts before approving development. eDNA testing provides a quick and effective way to satisfy this requirement.
When can eDNA samples be taken?
Samples must be collected during the approved survey window, typically from mid-April to the end of June, when newts are most active and their DNA is detectable in water. Surveys outside this window may not provide valid results.
How reliable is eDNA testing compared with traditional surveys?
eDNA testing is highly effective at detecting great crested newts when they are present. In some cases, it can be more sensitive than traditional survey methods. However, a negative result may still require follow-up if there are multiple ponds nearby or other risk factors.
What happens if the eDNA test is positive?
A positive result confirms that great crested newts are present. Further surveys, such as presence/absence or population assessments, may be required to plan mitigation measures and obtain any necessary wildlife licences before development can proceed.
How does eDNA testing help my planning application in Sussex?
Conducting eDNA testing early helps to avoid seasonal delays and ensures that planning applications are supported by robust ecological evidence. This can reduce the risk of planning conditions, delays, or additional surveys being required by local authorities.
