For seventeen year, Dartmoor National Park has been the theatre of a conflict between members of a small community, who have tried to live in a sustainable way in a wood they have bought, and the Dartmoor National Park Authority, which is the planning authority to whom local people have addressed complaints against the permanent settlement of the community. Hence it seems to be a classical environmental conflict which usually takes place in protected areas; the range of digital tools used for this media battle has made this case of the Steward Woodland Community an example in England. In order to raise money, new tools of communication and mobilisations have contributed to create new territory's contentious representations through the legal process and finally, it is the wider question of what should be the purposes of National Parks in England. Should they support sustainable initiatives or should they stick to the law and the rules already fixed? Once a precedent is pronounced, it could be difficult to go back.
