John K - I don't know about records of dormice, but my OH saw what he swore was a dormouse peeking out of a collapsed laburnum in a garden somewhere in Forest Hill several years ago. Pure anecdote, no evidence, I'm afraid. I wish I'd been there to see it as had the pleasure of rescuing one which had tumbled out of part of a barn wall which was being demolished many years ago in France. I handled it as briefly as possible as it was shaking with fright so I just put it in a safe dark place, and when I went to check on it after half an hour or so, it had gone. Hopefully, not into the belly of the resident whip snake.
