I might have to write to the right reverend Prelate on that. As we look as implementing the recommendations of the Landscapes Review, and through the biodiversity duty that we are imposing on public bodies through the Environment Act, I think we will address that. I hope we are seeing the determination of this Government to tackle issues which simply did not exist when national parks were created 70 years ago. Climate change was not talked about then and biodiversity was stable or rising; those emergencies need to be reflected in the policies they take forward.
