Since people seem to have been so interested in moles I've done a spot of digging... I spoke to Karin Attwood who has just posted here was de facto site manager at Rollright before I became involved. She is a board member of the Rollright Trust at present. As a result of talking to her I now know that the Rollright Trust did not hire anyone to kill any moles and has never had a policy of doing so. This is what Karin emailed me recently.

"The contract and payment for the mole treatment was awarded by EH. Therefore I have no idea how much was paid for the futile efforts to cut down on mole numbers. EH did not renew the contract and the Rollright Trust had, and continue to have no interest in doing so either. This was not Rollright Trust policy and the Trust did not hire the contractor. The moles are still there in abundance. The reinforced groundwork repairs (at some considerable expense) to the main walk areas seems to have deterred the moles from digging up the pathways, leading to safe level areas for visitors with physical or visual impairments, who continue to experience difficulty navigating the areas that have the moles are still active."

Don't blame the Rollright Trust for something it did not do. It did not and does not kill moles.
