The Dartmoor Preservation Association (DPA), was founded in 1883. It is a charity which provides an independent viewpoint on the current issues affecting Dartmoor and performs conservation work on archaeological sites. It opposes military training in the Dartmoor National Park, and seeks to preserve and increase public access to the Moor. Under the chairmanship of Lady Sylvia Sayer the DPA won the battle to halt a massive reservoir in the Swincombe Valley. More recently the author John Bainbridge worked as chief executive and led the campaign which saved Shaugh Moor and the Blackabrook Valley from china clay mining and waste tipping.
In recent years Bainbridge has been highly critical of the dumbing-down and more pro-establishment stance of the DPA.
