How we engage

Natural World Heritage sites are recognised as the planet’s most important protected areas, providing life-supporting benefits to millions of people worldwide. And yet, they are under increasing pressure from climate change, infrastructure development, mining, poaching and other threats.

IUCN is the official advisory body on nature under the World Heritage Convention. IUCN evaluates sites nominated for the World Heritage List and monitors the state of conservation of listed sites. IUCN aims to improve the management of World Heritage sites and enhance the role of the World Heritage Convention in nature conservation and sustainable development.
