One thought on “” Thank you for the video, I shall build a hibernaculum near the bottom of my garden. I have seen slow worms and grass snakes here in the past, although sadly not for a year or two. The level of part of this area was raised many years ago using rubble and broken bricks. Now I know why I found a metre long discarded Grass snake skin here a few years ago! Comments are closed.
