IUCN World Heritage Outlook

The first global assessment of natural World Heritage

The IUCN World Heritage Outlook is a new system assessing all 200+ natural World Heritage sites and is composed of a website and a report. Launched in 2014, it is the first global assessment of natural World Heritage and the first to recognize conservation success in the world’s most iconic places. Up to now, only about half of the listed sites have been regularly monitored through the UNESCO World Heritage Convention.





 The report is now also available in French and Spanish.

The IUCN World Heritage Outlook provides Conservation Outlook Assessments for all natural World Heritage sites. These assessments indicate whether a natural World Heritage site is likely to conserve its values over time, based on a desk-based assessment of:

  • The current state and trend of values
  • The threats affecting those values
  • The effectiveness of protection and management

Conservation Outlook Assessments also compile additional information on conservation issues, benefits and possible projects related to a site.

Backed by WCPA expertise, IUCN has developed this knowledge tool to fill the current knowledge gap on UNESCO natural World Heritage Sites and track their state of conservation.


  • Identify the most pressing conservation issues
  • Recognize well-managed sites
  • Show the benefits provided to people by these sites
  • Track the state of conservation of all natural World Heritage sites
