"Ÿou cross the green alder (green alder shrubland) mixed with the rhododendron moors. There are two types of green alder: one linked to the colonisation of abandoned pasture lands, the other to avalanche paths. In the second case, in the manner of Jean de la Fontaine’s reed, the alder ""bends but dœs not break"" as the avalanche passes. It is also an outstanding habitat for the black grouse (Tetrao tetrix), providing shelter and cover, particularly for rearing chicks."
