As the Advisory Body on natural World Heritage, IUCN is responsible for evaluating new sites nominated for inscription and for monitoring listed natural World Heritage sites. To ensure the highest quality of objective technical advice is provided, IUCN consults widely with experts who have relevant knowledge of the sites or the natural values they represent. The evaluation process is a rigorous, year-long process that involves field missions and desk reviews, as well as consultation at the international, regional and local level.
The IUCN World Heritage Panel is responsible for producing the official advice of IUCN on all nominations to the World Heritage List, taking account of all of the different inputs. The Panel can recommend inscribing or not inscribing a site, deferring a decision, or referring a nomination back to the country. The Panel also provides advice when necessary on particularly sensitive State of Conservation reports, which constitute the core of the World Heritage Convention’s reactive monitoring.
Recommendations are agreed on once all the information has been reviewed. The Panel proceeds whenever possible through consensus, although if this cannot be reached a vote is taken. IUCN’s World Heritage Panel follows a code of conduct to avoid potential conflict of interest, ensuring advice remains independent and science-based.
