Nominations

World Heritage status is one of the highest international recognitions on the planet. As such, every site inscribed on the UNESCO World Heritage List is carefully selected following a rigorous process.

IUCN evaluates all candidate sites nominated to the World Heritage List for their natural values, including sites known as 'mixed' that have both natural and cultural values.

The evaluation of nominations is over a year-long process involving IUCN's large network of experts. To ensure the credibility of the World Heritage List, it assesses the global significance, management, and integrity of the nominated sites. 

IUCN's evaluations combine field missions, desk reviews and voluntary input by experts with knowledge of the sites or the natural values they represent. All the information collected is reviewed by IUCN's World Heritage Panel to form IUCN's recommendations to the World Heritage Committee.

Thematic studies and gap analyses

Mobilising its wide network of experts, Members and partners, IUCN regularly conducts and updates thematic analyses to help States Parties and interested stakeholders assess the potential for nominating candidate sites to the World Heritage List. 

Thematic studies and gap analyses do not constitute IUCN's recommendations to the World Heritage Committee. Rather they offer guidance on enhancing the role of the World Heritage Convention in protecting globally significant natural areas on the World Heritage List.
