The Mont Blanc Environments

Alpine flora comprises all the plant species found in the Alps region.
Mountain vegetation changes gradually depending on altitude, sun exposure and the geographical situation of the massif. Five altitude zones (or bands) have been identified, each one of which supports different types of vegetation.
Foothill zone: pre-Alpine valleys and hills. The zone’s upper limit is at an altitude of 800m.
Montane zone: lower mountain zone, altitude between 800m and 1400m.
Subalpine zone: middle mountain and high altitude meadows, altitude between 1400m and 1800m.
Alpine zone: high mountain zone, at the snowline, altitude between 1800m and 3000m.
Nival zone: level covered in snow throughout most of the year that extends from the first perpetual snow level to above 3000m in altitude.

  • The alpine pasture

    At about 2000 metres, beyond the woodland’s upper limit, green meadows cover the mountain slopes and host a great variety of alpine species.

  • Alpine wetlands

    In the Alps, water meets the soil along glacial streams and ponds. In these environments, the soil is rich in moisture and even periodically flooded.

  • Talus slopes

    This natural environment is situated just below the limit of perennial snow. In these severe conditions, plants grow on loose detritus, sand and in thin soil often poor in nutrients.

  • Seasonal snow bank environment

    Is a small depression on the mountain slope where snow remains for more than nine months of the year.

  • Alnetum

    It’s vegetative association that often thrives on the sub-alpine plane, extends along crumbling slopes, humid north-facing detritic fans or along the banks of glacial streams.

  • Rhododendrum-vaccinetum

    It represents the gradual transition between the coniferous wood and the alpine pasture.
