Engiadina Val Müstair
The Swiss National Park was designated a biosphere reserve by UNESCO as early as 1979, until UNESCO carried out a comprehensive modernisation of the concept for biosphere reserves in 1995. The National Park no longer met UNESCO's new requirements, as it consists exclusively of a strictly protected core zone. This gave rise to the idea of establishing a maintenance and development zone in Val Müstair. With the Val Müstair joining the reserve, nothing stood in the way of the label being awarded again. On 2 June 2010, UNESCO provisionally awarded the label. Subsequently, the municipality of Scuol also agreed to the extension of the reserve on the north side. UNESCO then definitively awarded the label on 13 June 2017.
