Found widely in northern Europe, the population of this species is thought to have declined dramatically throughout its range. Great crested newts are protected under the Wildlife and Countryside Act 1981 (as amended), The Conservation (Natural Habitats &c.) Regulations 1994 (as amended) and the Countryside and Rights of Way Act 2000.
Declines have been attributed to habitat loss (ponds and terrestrial) resulting from agricultural intensification, development and drainage; habitat fragmentation, again resulting from agriculture and development; a reduction in suitable breeding sites following successional change; and the introduction of fish and wildfowl into once suitable habitat.
Surveying involves undertaking an initial ecological assessment of the site and ponds within the surrounding habitat to establish the likely presence of great crested newts.
If the habitat is considered suitable then a detailed great crested newt survey can be carried out by our licenced ecologists.
