Why a Mont-Blanc Atlas

Numerous scientific studies, of all disciplines, are conducted in the massif, including those of the CREA Mont-Blanc in alpine ecology. The ambitions of the Mont-Blanc Atlas are to restore this scientific diversity and to show the functioning of life and its evolution, in the form of indicators or synthetic analyses.
