Amendments to the criteria for the inclusion of natural properties in the World Heritage List and guidelines for the evaluation of nominations by IUCN
The Committee considered the complex issues concerning sites occupied by migratory species on a seasonal basis and decided to add to paragraph 11 on integrity in the "Operational Guidelines" a new sub-paragraph (v) as follows:
"In cases of migratory species, integrity will require critical areas necessary for the survival of the species to be included in the nomination. States which are parties to the Convention are requested to seek the co-operation of other States which contain seasonable sites for populations of World Heritage species so as to ensure that these species are protected throughout their full life cycle. Agreements of this nature should be noted in the nomination".
