Great crested newt adults are easily distinguished from the two other native newt species, the smooth and palmate newts, found in Britain today. The great crested newt is the UK’s largest newt, reaching a maximum adult overall length of about 170mm, although size varies between populations. Mature female length ranges from 90-170mm, typically reaching 110-130mm….
Great crested newts go into a period of dormancy between October and March with the females laying around 250 eggs between March and July wrapping each egg in a folded leaf underwater. It is estimated that there are about 75,000 populations in the UK, with a continuing decline of less than 5% between 1994 and…
Our quality assurance and experience make us the partner of choice for ecologists needing accurate and timely results. Our eDNA analysis adheres to Natural England’s protocol, so you can trust in our results. Why is proficiency testing important? Proficiency testing is an essential part of laboratory quality procedure, designed to provide evidence of the robustness…
Natural England’s March 2016 EPS mitigation licensing newsletter makes reference to great crested newt eDNA and degradation control but not everyone holds a degree in molecular biology. So what is the degradation control? And why is it important labs do this correctly when testing for newts? Degradation controls As specified in Appendix 2 of the…
If you haven’t heard, eDNA testing is the latest, highly effective method for detecting the presence of great crested newts in ponds, which ultimately can save developers and ecologists precious time and money. Just taking some of the highlights from DEFRA’s detailed methodological studies, where newt occupancy was assessed on four occasions at 35 sites, newts…
