Paragraph 88

“Integrity is a measure of the wholeness and intactness of the natural and/or cultural heritage and its attributes. Examining the conditions of integrity, therefore requires assessing the extent to which the property:

a) includes all elements necessary to express its Outstanding Universal Value;

b) is of adequate size to ensure the complete representation of the features and processes which convey the property’s significance;

c) suffers from adverse effects of development and/or neglect.

This should be presented in a statement of integrity.”

Paragraph 89

“For properties nominated under criteria (i) to (vi), the physical fabric of the property and/or its significant features should be in good condition, and the impact of deterioration processes controlled. A significant proportion of the elements necessary to convey the totality of the value conveyed by the property should be included. Relationships and dynamic functions present in cultural landscapes, historic towns or other living properties essential to their distinctive character should also be maintained.”

Paragraph 90

“For all properties nominated under criteria (vii) - (x), bio-physical processes and landform features should be relatively intact. However, it is recognized that no area is totally pristine and that all natural areas are in a dynamic state, and to some extent involve contact with people. Biological diversity and cultural diversity can be closely linked and interdependent and human activities, including those of traditional societies, local communities and indigenous peoples, often occur in natural areas. These activities may be consistent with the Outstanding Universal Value of the area where they are ecologically sustainable.”

Paragraph 101

“For properties nominated under criteria (vii) - (x), boundaries should reflect the spatial requirements of habitats, species, processes or phenomena that provide the basis for their inscription on the World Heritage List. The boundaries should include sufficient areas immediately adjacent to the area of Outstanding Universal Value in order to protect the property's heritage values from direct effect of human encroachments and impacts of resource use outside of the nominated area.”

Paragraph 102

“The boundaries of the nominated property may coincide with one or more existing or proposed protected areas, such as national parks or nature reserves, biosphere reserves or protected cultural or historic districts or other areas and territories. While such established areas for protection may contain several management zones, only some of those zones may satisfy requirements for inscription.”

Paragraph 164

“If a State Party wishes to request a minor modification to the boundaries of a property already on the World Heritage List, it must be prepared in compliance with the format of Annex 11 and must be received by 1 February by the Committee through the Secretariat, which will seek the evaluation of the relevant Advisory Bodies on whether this can be considered a minor modification or not. The Secretariat shall then submit the Advisory Bodies’ evaluation to the World Heritage Committee. The Committee may approve such a modification, or it may consider that the modification to the boundary is sufficiently significant as to constitute a significant boundary modification of the property, in which case the procedure for new nominations will apply.”

Paragraph 122

"122. The Preliminary Assessment is a mandatory desk-based process for all sites that may be nominated to the World Heritage List and is undertaken following a request by the relevant State(s) Party(ies). Information included in the Preliminary Assessment request should build on the information provided in the Tentative List and also on any Upstream Process advice and/or Preparatory Assistance and its outcome must be provided at least one year before a full nomination dossier can be submitted by the State(s) Party(ies).

In particular:

a) The Preliminary Assessment provides States Parties with an opportunity for enhanced dialogue with the Advisory Bodies, and it will help to establish the feasibility of a potential nomination and avoid the use of resources in the preparation of nominations that may be unlikely to succeed. 

b) The Preliminary Assessment provides guidance on the potential of a site to justify Outstanding Universal Value, including integrity and/or authenticity, and, if information is provided, on the requirements for protection and management. The decision to prepare a full nomination dossier, regardless of the outcome of the Preliminary Assessment, will rest with the concerned State(s) Party(ies).

c) States Parties shall submit their Preliminary Assessment request to the World Heritage Centre according to the timetable set in paragraph 168, and using the standard format provided in Annex 3. The request shall be submitted in English or French, in paper and electronic formats (Word and/or PDF format) and in the required number of printed copies (same as for nomination dossiers): 2 identical copies for cultural and natural sites, and 3 identical copies for mixed sites and cultural landscapes.

d) On receipt of Preliminary Assessment requests from States Parties, the Secretariat will acknowledge receipt, check for completeness (in compliance with Annex 3) and register them. The Secretariat will forward, according to the timetable set in paragraph 168, complete Preliminary Assessment requests to the relevant Advisory Body(ies) for desk review. If necessary, the Advisory Body(ies) will request any additional information from the State(s) Party(ies), which should be submitted to the Secretariat. From the commencement of the Preliminary Assessment, the Advisory Body(ies) will initiate a dialogue with the concerned State(s) Party(ies) to establish a point of contact and agree on the process of exchange. States Parties are encouraged to appoint a technical focal point to ensure that dialogue is effective throughout the process, and to ensure that the conclusions of the Preliminary Assessment are communicated to the relevant stakeholders.

e) The Preliminary Assessment will be undertaken by ICOMOS and IUCN on a joint basis whenever relevant, and will be an independent desk review, which will include consultation with expert reviewers.  No mission to the site will be undertaken (see Annex 6). Based on available information, the conclusions of the assessment will include an indication of whether the site may have potential to justify Outstanding Universal Value. If so, specific guidance and advice, in the form of recommendations, will be provided to assist the State(s) Party(ies) in the development of the nomination dossier. The Preliminary Assessment Report by the Advisory Bodies shall be provided to the State(s) Party(ies) via the Secretariat in one of the two working languages of the Convention. 

f) The Preliminary Assessment Report by the Advisory Bodies is relevant for up to 5 years. A new Preliminary Assessment is required if a nomination is not submitted by 1 February on the fifth year following the transmission of the Report to the concerned State(s) Party(ies). 

g) A State Party may withdraw a Preliminary Assessment request it has submitted, at any time.  In such circumstances, any further consideration of a possible nomination will need to be subject to a new request for a Preliminary Assessment.

h) At each session of the World Heritage Committee, the Secretariat will provide a list of Preliminary Assessments requests received and those undertaken, but will not indicate the guidance given by the Advisory Bodies to the concerned State(s) Party(ies) in a completed Preliminary Assessment. However, once a nomination is submitted, the related Preliminary Assessment Report shall be annexed to it.

i) Both Upstream Process and Preliminary Assessment imply guidance at an early stage, prior to the preparation of a nomination, however they are different mechanisms. The Upstream Process is not mandatory. The Preliminary Assessment is a mandatory phase possibly allowing access to the preparation of a nomination dossier. Within an Upstream Process a visit to the site may be possible, while the Preliminary Assessment is carried out exclusively on the basis of a desk review.  The Upstream Process may provide general advice, in relation to revision of a Tentative List, while the Preliminary Assessment is undertaken on a single site (whether serial or not) already included on a State Party’s Tentative List. While in general the costs of Upstream Process requests are borne by the requesting State(s) Party(ies), the costs of Preliminary Assessments, being part of the nomination process, are included in the related evaluation process (see also Paragraph 168bis). In terms of sequence, Upstream Process advice should precede the Preliminary Assessment."
