Sheer cliffs of Avon Gorge have goat population

Stopped to take a phone call and saw amateurs taking instruction in climbing sheer rock sides and way above was this goat helping to keep the foliage in check. There are several plants here that are found only here and there is no other way they can be allowed to thrive. (My gardener daughter says they do grow some of the plants and keep seeds at Kew Gardens!)
