Our fragile natural environments

The territory of the Chamonix Valley is located in an exceptional natural setting. Eternal snow, glaciers, mountain pastures, forests, high-altitude lakes and wetlands wherever you are, these landscapes are within your reach.
Very early on, local authorities became aware of the special nature of their environment and its fragility by carrying out numerous actions.Today, this competence has been taken over by the Community of Communes, which wishes to reconcile environmental protection, human activities and public awareness by carrying out actions to protect, manage and enhance natural areas with its partners.

Sensitive natural zones

More than 90% of the territory of the Chamonix Valley is covered by protective rules and regulations. Whether they are regulatory or not, these measures can lead to management plans or specific action programs.

- The Aiguilles Rouges Nature Reserve, 3279 hectares;
- The Vallon de Bérard Nature Reserve, 540 hectares;
- The Carlaveyron Nature Reserve, 598 hectares.

In Haute-Savoie, the State has delegated the management of Nature Reserves to ASTERS, Conservatoire des Espaces Naturels. A management plan has been drawn up for these three reserves, it sets the main objectives and the actions to be taken in order to protect the natural heritage by 2022. At the same time, the animation and awareness missions have been entrusted to the Community of Communes of the Chamonix Mont-Blanc Valley.
