The original National Parks cover 9% of the land area of England and Wales and provide pleasure for millions of people (Fig. 1). A recent survey by the countryside agencies estimated that in 1994 a minimum of 76 million recreational visitor days were made to the Parks as a whole. This is equivalent to ≈ 1.5 visitor-days for each person living in England and Wales. The survey confirmed that the main reasons why people chose to visit the Parks, rather than going somewhere else, was primarily the scenery and landscape, followed by peace and quiet; these aspects are part of the distinctive appeal of National Parks and two of the qualities for which they were established (Fig. 2). However, the underlying geology, which contributes to the special appeal and natural beauty of these areas, also draws another kind of user. National Parks are not just natural assets in terms of landscape but are also regarded as valuable sources of minerals for industrial and other uses. The same minerals that have created the beauty of the unique landscapes of National Parks are used for building roads, for the construction industry and in chemical processes, and their extraction has been a major contributor to the trend of ‘deteriorating environmental quality’ and ‘permanent damage to the landscape’ found by the 1991 National Parks Review Panel (the Edwards Panel).
