Keep your eDNA happy in the sun

Why should I test for Great Crested Newts?
Great Crested Newts are protected by UK law and it’s illegal to disturb, obstruct or destroy GCN habitats. Newts can be hard to spot but our eDNA surveys allow you to detect them. Order your kit today before the season ends 30th June.
If your project involves any of the below, a GCN survey will likely be required:
- Work within 500 metres of standing water bodies, like ponds or ditches
- Projects within 1km of recorded GCN locations
- Development of sites with aquatic breeding or terrestrial resting habitats for GCN

GCN Reporting
Our Portal allows you to easily control which kits are included in a report. Kits returned together and assigned to the same Portal 'project', will be reported together.
Before our courier arrives for collection, please check that each project has the correct kits assigned to it and that all kits to be reported together are being returned together. Once your used kits have been collected, you cannot re-assign kits to different projects as this change will not be recognised in your reporting. Example report available here.
