  Title: List of national parks of England and Wales
  Passage: Within England and Wales there are thirteen areas known as national parks, each administered by its own national park authority, a special purpose local authority, the role of which as set out in the Environment Act 1995 is: "to conserve and enhance the natural beauty, wildlife and cultural heritage of the National Parks."  and "to promote opportunities for the understanding and enjoyment of the special qualities of the National Parks by the public."  The national park authority for each park addresses these aims in partnership with other organisations, such as the National Trust.  In cases where there may be conflict between the two purposes of designation, the first must take precedence under the Sandford Principle.  The national park authorities also have a duty to foster the economic and social wellbeing of communities in pursuit of these purposes.
