I am grateful to my right hon. Friend. We are currently reviewing the position on national parks and the designations that we make around the country. I have asked for the Chilterns AONB to have a stronger designation in order to give it protection. Does he agree that we should see whether the chalk streams in our country could get a higher designation for protection? Does he agree that this would be a golden opportunity to lift that level of protection, particularly for this rare habitat and environment?
