IUCN is the advisory body on nature to the World Heritage Committee.
As the official advisory body on nature under the World Heritage Convention, IUCN makes recommendations on sites aspiring to achieve World Heritage status and on necessary action to conserve listed sites facing threats. The World Heritage Committee has the final say.
IUCN's recommendations for 2016 are issued in two releases six and fours weeks before the World Heritage Committee meeting. The Committee's decisions will be published by UNESCO's World Heritage Centre in October.
IUCN evaluates all natural and 'mixed' sites nominated for World Heritage status, and contributes to evaluations of certain cultural landscapes.
Each year, IUCN prepares monitoring reports for about 60 sites listed for their natural values, in collaboration with UNESCO's World Heritage Centre
