Female GCN lay eggs individually on leaves of submerged vegetation, which she then carefully folds up into a package. After about 3 weeks the larvae hatch out and spend the next 2 to 3 months developing into juveniles, whilst feeding on a wide variety of pond life including small crustaceans and other newt larvae.
Great crested newt pond scoping survey in Lower Peover, Cheshire
UES were commissioned in June 2011 to conduct a great crested newt pond scoping survey to assess potential presence of great crested newts within 250m of the development footprint.
Development works within 250m of a great crested newt pond are often subject to a Natural England European Protected Species Licence (EPSL). It is stressed by Natural England to try and redesign a project to remove any potential impacts on great crested newt populations and associated habitats in order to remove the need for licensing.
The field methods used to survey ponds are:
1. Bottle trapping
2. Egg search
3. Torch surveys
Natural England recommend using at least three of the methods outlined above when conducting a pond survey. Smooth newts and great crested newt eggs and larvae were found in ponds within 250m of the development.
UES proposed that by designing the project timings and working methods to avoid impacts, any potential impacts on local great crested newt populations and habitats could be effectively removed, or reduced to a negligible level thereby removing the need for protected species licensing.
