Amphibians

There are six native species of amphibian in the UK: Rana temporaria common frog, Bufo bufo common toad, Epidalea calamita natterjack toad, Lissotriton vulgaris smooth newt, Lissotriton helveticus palmate newt and Triturus cristatus great crested newt.  Great crested newt (GCN) and natterjack toad are both European Protected Species, but, while natterjack toad is only encountered in a few places in the UK, great crested newts are relatively widely distributed across large areas of the UK, where their breeding ponds remain.  There are also populations of non-native and re-introduced species in some parts of Britain.

Populations of great crested newts within or near to development sites will require careful consideration during the development process and a development licence based on accurate and up to date survey may be required.  Richard Graves Associates provides the following services in relation to great crested newts:

  • Habitat Suitability Index (HSI surveys assess the suitability of ponds to support GCN)
  • Presence / absence surveys
  • Population surveys
  • Mitigation advice and design
  • Licencing
  • Receptor site selection and design
  • GCN masterplanning
  • Translocation
  • Monitoring.

Timing

Survey timing is crucial for GCN, as under current guidance: http://naturalengland.etraderstores.com/NaturalEnglandShop/UserFiles/Files/newt1.pdf population survey information must be obtained between mid-April and mid-May
