4. Assessment Against World Heritage Criteria

The fundamental criterion for a place to be entered in the World Heritage List is that it should be “of outstanding universal value.” This concept of outstanding universal value has been teased apart in the Operational Guidelines for different categories of value to produce a total of 10 specific criteria: six criteria for cultural properties and four criteria for natural properties. The four natural heritage criteria are being used in developing this nomination. These are given in Paragraph 44 of the Operational Guidelines (Attachment 1).

Sites nominated should therefore:

(i) be outstanding examples representing major stages of earth's history, including the record of life, significant on-going geological processes in the development of land forms, or significant geomorphic or physiographic features (Geoevolutionary history); or

(ii) be outstanding examples representing significant on-going ecological and biological processes in the evolution and development of terrestrial, fresh water, coastal and marine ecosystems and communities of plants and animals (Biological evolution); or

(iii) contain superlative natural phenomena or areas of exceptional natural beauty and aesthetic importance (Superlative beauty); or

(iv) contain the most important and significant natural habitats for in-situ conservation of biological diversity, including those containing threatened species of outstanding universal value from the point of view of science or conservation (Biological diversity).

(The terms in bold are the shorthand references to the criteria that will be used through this Report.)

In addition, a nomination under any natural heritage criterion must meet conditions of integrity, the requirements of which are outlined in detail in the Operational Guidelines (see Attachment 1). To meet the conditions of integrity, a nominated area should include all the elements necessary to express its outstanding universal value, be an adequate size to ensure the complete representation of the features and processes which convey the property’s significance, and be free from adverse effects of development and/or neglect.

An area nominated under criterion (i) should contain all or most of the key interrelated and interdependent elements in their natural relationships. Examples given in the Operational Guidelines are: an "ice age" area should include the snow field, the glacier itself and samples of cutting patterns, deposition and colonization (e.g. striations, moraines, pioneer stages of plant succession, etc.); in the case of volcanoes, the magmatic series should be complete and all or most of the varieties of effusive rocks and types of eruptions be represented.

An area nominated under criterion (ii) should be of sufficient size and contain the necessary elements to demonstrate the key aspects of processes that are essential for the long-term conservation of the ecosystems and the biological diversity they contain. Examples given in the Operational Guidelines are: an area of tropical rain forest should include a certain amount of variation in elevation above sea-level, changes in topography and soil types, patch systems and naturally regenerating patches; similarly a coral reef should include, for example, seagrass, mangrove or other adjacent ecosystems that regulate nutrient and sediment inputs into the reef.

An area nominated under criterion (iii) should be of outstanding aesthetic value and include areas that are essential for maintaining the beauty of the site. The example given in the Operational Guidelines is: a site whose scenic values depend on a waterfall, should include adjacent catchment and downstream areas that are integrally linked to the maintenance of the aesthetic qualities of the site.

An area nominated under criterion (iv) should contain habitats for maintaining the most diverse fauna and flora characteristic of the biogeographic province and ecosystems under consideration. Examples given in the Operational Guidelines are: a tropical savannah should include a complete assemblage of co-evolved herbivores and plants; an island ecosystem should include habitats for maintaining endemic biota; a site containing wide-ranging species should be large enough to include the most critical habitats essential to ensure the survival of viable populations of those species; for an area containing migratory species, seasonal breeding and nesting sites, and migratory routes, wherever they are located, should be adequately protected; international conventions, e.g. the Convention of Wetlands of International Importance Especially as Waterfowl Habitat (Ramsar Convention), for ensuring the protection of habitats of migratory species of waterfowl, and other multi- and bilateral agreements could provide this assurance.
