The massif contains a very rich variety of biodiversity as a result of the huge height range and different habitats found between the valleys and the highest summits.
Mild temperatures occur at altitudes between 600 and 1,000 metres (2,000 and 3,300 ft), whereas arctic conditions occur from 2,500 metres (8,200 ft) up to the highest point at 4,808 metres (15,774 ft).

Whilst the Mont Blanc massif does not contain any species that are endemic to it, there are many rare and legally protected species found within its four major habitat zones.
These are the: montane forests, sub-alpine, alpine and nival zones.
The major habitats are coniferous forests, moors, rock and talus slopes, plus glacial moraines.
The biological richness is further influenced by the different aspects of the faces, by the geology, and by the influence of man on the lower and middle slopes where forest clearance has created open grassland.
The native forest habitats are essential for the survival of many species, with the key conifer species including larch, pine, stone pine and red pine.
