In response to an email re above and proposed GDF site, here is their response, dated 17th February 2025:
Yes, possible impact on natterjack toads is a concern.
As this is still at the area of search phase it is difficult to decide what any impacts might be, it very much depends if a firm proposal comes forward and what it might actually look like.
The Haverigg sand dunes as the critical area for natterjacks that looks like it might be affected by this is part of the Duddon Estuary SSSI and Morecambe Bay SAC which are the national and international level conservation designations, so if a firm proposal does come forward, there is likely to be a very large amount of environmental impact assessment work to be done before any decisions are made.
