On the 28th of April 1978, UNESCO declared Montseny a biosphere reserve on
the request of the managing body of the park and the Spanish
Committee for the MAB (Home and Biosphere) Programme. This
category has allowed Montseny to figure in different international
forums, and to carry out trials of a territorial management
model which extends beyond its administrative limits. In 1987,
the Catalan government declared the area a natural park.
