The alpine moor is home to several species of sub-shrubs. Adapted to the snow-capped slopes, the hardy ferruginous rhododendron bursts with light from the beginning of summer. More fragile in appearance, the foliage of blueberries and cranberries is a tender green, before turning red in autumn. Their blue berries are enjoyed by a variety of fauna, from the fox to the black grouse. Hiding in the heart of this moor is the discreet alpine clubmoss, similar to ferns but with very primitive features.
