The Cornettes de Bises massif and the Dent d’Oche are classified as a National Heritage Site for their picturesque character and the quality of their landscape. Natura 2000 areas such as the Mont de Grange and the Delta de la Dranse nature reserve bear witness to the area’s remarkable natural wealth.

The Natura 2000 network

The Natura 2000 network brings together natural sites in the European Union that are of great heritage value in terms of the flora and fauna they contain. Leman Mountains Explore brings together two sites in this European biodiversity network: the Cornettes de Bise massif and Mont de Grange.

The approach adopted by the Natura 2000 network encourages collective collaboration with a view to the balanced and sustainable management of areas, taking into account both the economic and social dimensions. All the classified natural sites in the area demonstrate the mosaic of natural environments and the ecological interest of the region.

Our classified natural areas

The Dranse Delta reserve

There is no shortage of measures in place to protect the region’s natural assets: ZNIEFF (Zone Naturelle d’Intérêt Ecologique, Faunistique et Floristique), Biotope Protection Orders, listed sites, ENS (Espaces Naturels Sensibles), RAMSAR sites (Convention on Wetlands of International Importance), Natura 2000 zones and nature reserves.

The Dranse Delta reserve is one of the region’s major assets. Located on a migration route, it is home to almost 800 species. Managed by Asters, the Conservatoire d’Espaces Naturels de Haute-Savoie, the reserve is open to visitors all year round. Events, visits and exhibitions are organised at the Maison de la Dranse in Publier.

Le Mont de Grange

Mont de Grange, a summit shared by three communes (Abondance, La Chapelle d’Abondance and Châtel), is the highest point in Leman Mountains Explore. Its limestone marl and schist reliefs are softer than the limestone of the Cornettes. The massif is home to a diverse range of wildlife, including chamois, mouflons, deer, eagles and even rock partridges and ptarmigan.

With its lake ecosystems, migratory bird corridors, diverse forests, wetlands and snow-covered valleys, this region is packed with breathtaking scenery. The diversity of its flora and fauna testifies to the incomparable richness of its habitats.
