Since 1979 the SNP is a designated UNESCO Biosphere Reserve.
Since 2010 the Biosphere Val Müstair and the SNP are established as a Biosphere Reserve Engiadina Val Müstair.
At the moment work is going on, in collaboration with the Val Müstair, to establish the Biosfera Engiadina Val Müstair where the SNP will form the core zone. Since 1.1.2016 the community of Scuol is the third co-operation partner. The definitive acceptance of the UNESCO is expected in 2017.
Informations about the actual development, the scope and projects of the management plan are here (in german).
