In the 19th century, Mont Aigoual was almost totally bare of trees. Intensive use of the forest and the pressure of transhumant grazing together with the harsh local climate caused devastating floods. The rich vegetation of the grazing grounds was replaced by heather pastures and many gullies. In the valleys huddling at the foot of Mont Aigoual, terrible floods pushing tons of stones downstream carried off roads and pastureland. In response, a reforestation programme was launched in the second half of the 19th century, which created the forest you see today. Nowadays, the forested Aigoual massif protects the valleys while at the same time providing a space for economic production, biodiversity and leisure.
