The Passy Nature Reserve sums up the mountain history of Haute-Savoie:
- the natural environments: the young cliffs of Fiz dominating the rolling hills of old Pormenaz, the formidable thrust of the Alps opposing their siliceous and limestone nature. From this mineralogical contrast was born the diversity of environments (lawns, moors, wetlands) and alpine species (ibex, eagles, etc.)
- fauna: chamois, ibex, eagle, marmot, grouse, rock ptarmigan, bearded vulture...
- the flora: 530 species have been listed including the Saint-Bruno lily, the martagon lily or even the moss campion...
- flies and biodiversity: syrphids, a kind of fly, are excellent indicators for scientists. The clearing operations in Pormenaz make it possible to assess biodiversity.
