ONF agents' protest sign. Starting from Mulhouse, Perpignan, Strasbourg and Valence, forest rangers from the ONF, the French National Forestry Office, began a long march of more than 300 km on 25 October 2018, lasting around 40 days. They were about 2000 to take turns along the route to say NO to the industrialisation of the French forest and to shout loud and clear that the forest is not a wood factory.
