CONF 003 XI.(b).37
Amendments to the criteria for the inclusion of natural properties in the World Heritage List and guidelines for the evaluation of nominations by IUCN
In view of the difficulty of assessing nominations without an adequate inventory, the Committee decided to encourage States Parties to prepare such inventories. It was furthermore decided to ask IUCN to prepare a proposal for the next meeting of the Bureau relating to the methodology and cost of preparing an inventory on a global basis.
