The landscape is organised into three “levels”, mainly determined by the average annual temperature which drops dramatically with as the altitude increases.

There are many natural habitats for flora which is both original (volcanic soils) and exceptional: diversity and number of rare and protected species represented.

Immense forests, beech groves or fir plantations have all been around a long time and have up until now preserved a rare and multi-colour flora. Among the more common species you will find the Austrian leopard’s bane, Scilla lily hyacinth, or even the emblematic Martagon lily. The highland forests are fragile and must not be intensively exploited.

Wetlands, flooded marshland or peat bogs formed during glaciations host an abundance of flora which is often specialised. Carnivorous plants like the Round-leaved sundew or Butterwort, but also strangely-shaped and slender plants such as Cottongrass, or Hedge-garlic adenostyle with enormous leaves.
