Riparian forest

The track runs through a wood of alder, beech, aspen and oak, the remnant of the natural forest growing at the water's edge, called riparian forest. This type of forest is in decline everywhere, destroyed by urbanisation and by containment of the mountain streams. Yet it is an essential zone for the fixation of river banks and for purifying the water. Since it offers specific natural habitats, it also plays a major role in maintaining biodiversity.
