Pine forest

The uphill section is in forest that partly stems from reforestation in the 1930s. First, there are Scots pines, whose patchy canopy lets through enough light for a grassy undergrowth to develop. A little higher up, a tightly reforested area of Douglas firs has no understory: no plants can grow for lack of light. Higher still, the undergrowth thins out here and there, and chestnuts reappear. There is a huge tree stump to the right of the path, a vestige of an ancient chestnut grove belonging to Broussous.
