  Slash-and-burn

  This technique consists of clearing weeds and shrubs using fire: the fire is utilised to get rid of broom, especially in places that a motorised shredder cannot access. Slash-and burn is carried out every 4 to 5 years in a zone chosen by the farmer. Over larger areas, it is supervised by the fire brigade. In the 19th century, 100,000 sheep migrated to summer pastures here (transhumance) and joined the plateau herds, leaving no room for broom. As soon as the meadows are no longer grazed, they are colonised by broom, then shrubs, then forest. These open spaces are due to human activity (clearing) to allow herds to graze on grass. Grazing prevents the spontaneous growth of shrubs and any generalised invasion of forest.
