This group were in one of my compost bins a few years ago. I see them regularly in the garden and saw my first of the year last week, one of last year's new brood. There was also a grass snake sharing the compost bin with the slow worms that year but it was much too fast to catch with the camera whereas the slow worms lived up to their name.
I found a grass snake today when I was clearing debris from around my garage. I scooped up a spade full of debris and deposited it in the barrow and was surprised to see a foot long young snake looking a bit disorientated in the middle of the barrow. I had been keeping an eye open for more slow worms but the grass snake was a bit of a shock. Thankfully it was unharmed and I relocated it to some nearby vegetation.
