Engiadina Val Müstair Biosphere Reserve

The Engiadina Val Müstair Biosphere covers an area of around 450 km² in the alpine regions of the canton of Graubünden. The reserve consists of the Swiss National Park, which serves as the central protected area, and the valleys north and south of the Ofen Pass. The valleys form the buffer zone, where protection measures are located, and the transition zones with settlements and economic activities. The highest biosphere in the Alps is one of the most species-rich areas in Switzerland and Europe in terms of plant and animal species.
