Introduction An ecological character description (ECD) for the Edithvale-Seaford Wetlands was published in 2012 (DSE 2012) but drafted prior to 2008 and did not follow the National Framework and Guidance for Describing the Ecological Character of Australia’s Ramsar Wetlands (Department of the Environment, Water, Heritage and the Arts 2008). The ECD identifies critical ecosystem services does but not identify critical components and processes and does not contain any Limits of Acceptable Change (LAC) for critical components, processes and services (CPS). The benchmark description of the site, however, is thorough and reflects conditions at the time of listing. This addendum includes out the following amendments to the ECD. • There has been a review of the Criteria for Identifying Wetlands of International Importance (Ramsar criteria) met by the site. • A translation has been made of the identified ecosystem services in the ECD to critical CPS following the requirements of the national framework (Department of the Environment, Water, Heritage and the Arts 2008). • LAC have been developed for the critical CPS. • A list of threats to the Ramsar site has been added. 2. Ramsar criteria 2.1 Changes resulting from a review of the Ramsar criteria This review, based on a more rigorous application of the Ramsar guidance, indicates that the Edithvale- Seaford Wetlands Ramsar Site met three of the current nine criteria at the time of listing in 2001 (criteria 2, 4 and 6) but not criteria 1 and 3 as claimed in DSE (2012) . A check of recent additions of species as threatened under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) has resulted in an additional species being identified as contributing to Criterion 2 being met. Criterion 4 was not considered to have been met in DSE (2012). However, there is evidence that the site met, and continues to meet, this criterion as it supports wetland-dependent species during the critical lifecycle stages of migration and breeding. The changes are summarised in Table 1. Table 1. Summary of changes to the criteria met by the Edithvale-Seaford Wetlands compared with DSE (2012). Criteria met Comments Ramsar listing criteria At listing Currently Changes since DSE (2012) The curlew sandpiper was listed as Criterion 2: A wetland should be critically endangered under the EPBC Act considered internationally important if it in 2015 and was not identified as meeting supports vulnerable, endangered, or Yes Yes this criterion in DSE (2012).

Criterion 1: A wetland should be considered internationally important if it contains a representative, rare, or unique No No example of a natural or near-natural wetland type found within the appropriate biogeographic region. More rigorous application of the Ramsar guidance indicates these criteria were not Criterion 3: A wetland should be met at listing considered internationally important if it supports populations of plant and/or animal No No species important for maintaining the biological diversity of a particular biogeographic region. 2.2 Justification for the site not meeting Ramsar criteria 1 and 3 Criterion 1 A wetland should be considered internationally important if it contains a representative, rare, or unique example of a natural or near-natural wetland type found within the appropriate biogeographic region. The appropriate bioregion for the site is the South East Coast (Victoria) drainage division which includes all of the coastline of Victoria and a small portion of the southern NSW and South Australian coasts (Department of the Environment, Water, Heritage and the Arts 2008). There is no comprehensive wetland inventory for this bioregion. As such the application of the terms “representative” and “rare” are difficult. In terms of “representative”, advice from the Convention (Ramsar 2009) is that contracting parties should select the “best examples” of each wetland type within
