Terrestrial biodiversity and the World Heritage List : identifying broad gaps and potential candidate sites for inclusion in the natural World Heritage network

The World Heritage List includes 156 properties explicitly recognized for their outstanding biodiversity values, which together represent the worlds major ecosystems. However, some areas with outstanding biodiversity values are still not part of this network of biodiversity World Heritage sites. To address this issue, IUCN and UNEP-WCMC have developed this global thematic study, with a focus on the terrestrial realm.
