I managed to get to the Mendips last week and took the family down Goatchurch where I was surprised to find roosting bats. Back in the day (some 30 years ago) when I used to cave on Mendip, there were too many novice trips in the cave for the bats to roost. Does anybody know what's happened? Has there been a big reduction in trips down goatchurch? Have the bats become used to cavers in goatchurch? Have the bats lost other roosting sites?
