The World Heritage List

The World Heritage List currently comprises 1223 properties of Outstanding Universal Value, including 271 sites inscribed for their natural values (231 natural and 40 mixed sites). As the Secretariat of the World Heritage Convention, the World Heritage Centre - hosted by UNESCO - keeps track of the��, including a description of why each site was inscribed on the List, maps of the inscribed property and surrounding buffer zone, as well as relevant documentation (nomination dossier, ������ϲʿ�������ֳ�ֱ�� evaluation, ������ϲʿ�������ֳ�ֱ�� advice, reports from governments, decisions from the World Heritage Committee).

Shapefiles of all natural World Heritage sites are available on the World Database on Protected Areas, using��, as well as on����or UNESCO’s��.

Why is natural World Heritage important?

World Heritage sites enjoy the highest level of international recognition through the 1972 World Heritage Convention, as places so valuable that their conservation transcends boundaries, cultures and generations. Our ability to secure the highest quality of protection to natural World Heritage sites is therefore a litmus test of the effectiveness of nature conservation more broadly.

Although there are relatively few natural World Heritage sites compared to other types of protected areas, they cover very large areas that represent the best of nature. The 266 sites currently inscribed on the World Heritage List for their natural values cover about 8% of the world’s total protected lands and seas.
