Who can be making these tunnels
Hello. Hope someone can make a suggestion. I live in a fairly rural location with a large size garden. Several areas around the garden (around a compost bin, under an apple tree and near an old foundation for a shed) have become riddled with shallow tunnels. So much so that walking around the garden has become a hazard as the ground tends to give way underfoot when I least expect it.
At first I had assumed it was moles but I don't get the typical mole hills anywhere so I'm beginning to doubt what it would be. Does anyone have any suggestions what could be digging this underground 'city'. I have seen once a weasel apparently trying to catch something in one of these areas.
