The ecological continuity of protected natural areas

With the Grande Sassière Nature Reserve behind it, the Baillettaz Nature Reserve, together with the Vanoise National Park and the Italian Gran Paradiso, forms the largest protected area in Europe. In terms of environmental preservation, the proximity of these protected areas ensures the ecological continuity between different mountain massifs, which has resulted in the return of the alpine Ibex by natural recolonisation from the Gran Paradiso.
