Digging for valuable ball clay makes ugly scars across the Devon countryside. But Nature soon makes good the damage, and interesting newcomers like the grass snake, water spider, and that entertaining character the water shrew are able to move in. In time the claypits become attractive to naturalists, fishermen, and the local inhabitants-perhaps the very people who opposed the ugliness in the first place. How does all this happen?
