From the 13th to the mid-19th century, Mont Ventoux was intensely deforested for the benefit of Toulon's shipbuilding, charcoal making, and sheep grazing. In the recent period of the massif's history, man has thus become an active agent in the modification of the relief of the mountain by jeopardizing the stability of the topography of its northern slope and accelerating its erosion through intensive deforestation. The reforestation of the Ventoux massif began in 1858 with the massive planting of truffle oaks and local varieties (beech, pine) but also exotic species such as Austrian black pines and especially Atlas cedars.
