Good to know they are still up and running after all these years Herptastic, thanks for that. As a further update I contacted the Berwick upon Tweed Wildlife Group and they feel it is unlikely to have been a sand lizard (though not impossible) and there are common lizards in the area so it could have been a green version of that species. Apparently the Holy Island (Lindisfarne) Warden is responsible for the sand dunes along the Northumberland coast so they are kindly going to pick his brains to see if any have ever been recorded. In Spring I shall return to the spot and patiently wait and endeavour to get a photo and that should resolve the issue. I'll keep you all posted.
