"L'allée des Gardes", rows of large coniferous trees, refers to the forest rangers who manage this massif. Behind this alley, the forest is managed through natural regeneration (as opposed to planting seedlings and young plants from nurseries): the undergrowth is cleared, some beautiful preserved trees play the role of seed trees. The seeds grow into a shrub; gradually the "old" seed trees are eliminated to make way for the young shoots.
