Many natural parks protect this particular nature and various committees have undertaken to propose the Dolomites as a UNESCO World Heritage site, a successful attempt on 26 June 2009, when in Seville the twenty-one members of the World The Heritage Committee unanimously decided to include almost all the Dolomites in the list of natural heritage. The nomination was initially advanced in 2004 by the Ministry of Cultural Heritage, but was rejected by UNESCO in May 2006. Subsequently the UNESCO Working Group of the Ministry for the Environment and the protection of the Territory and the sea, coordinated by Prof. Pier Luigi Petrillo, has resubmitted the two application dossiers, initiating, at the same, an intensive negotiation with the 165 Member States of the Convention and the 37 member States of the Committee. At the conclusion of the two-and-a-half year negotiations, the independent evaluation Authority for naturalistic applications, the IUCN, has delivered a favourable opinion on the application. Finally, in Seville, in June 2009, the team coordinated by Prof. Petrillo led the last final negotiations obtaining the recognition of UNESCO that "certifies" the uniqueness, in the world, of the Dolomites.
