Population Status and Trends. (i) Supported the review by PaCSWG of information concerning the global threat status (IUCN Red List Category of Extinction Risk) for all ACAP species to ensure consistency and strict adherence to the IUCN Categories and Criteria (published 2012), and to the Guidelines for using the IUCN Categories and Criteria (published 2017).
Population Status and Trends. 12.5.1 The WGs discussed BSWG4/STWG6 Doc 5 by BirdLife International, which identifies candidate BirdLife Important Bird Areas (IBAs) in the Atlantic sector of Antarctica (including the South Shetland and South Orkney Islands). The only ACAP species breeding in this area is the Southern Giant Petrel Macronectes giganteus, populations of which would only trigger IBA criteria if they exceed 1% of the global population (c. 485 pairs). However some IBAs triggered by other seabird species also contain breeding giant petrels. The IBA analysis, taking account of different levels of certainty over population data and also examining sensitivity to scale-dependent effects, identifies some 40 “confirmed” IBAs and 60 “potential” IBAs. Of the “confirmed” IBAs, Southern Giant Petrels breed at two, Avian Island (Antarctic Peninsula; 197 pairs) and Penguin Island (South Shetland Islands; 634 pairs). Of the “potential” IBAs, Southern Giant Petrels breed at ten. Overall, the IBAs identified include all six of the important breeding sites for ACAP Species holding >1% of the global population.
Population Status and Trends. 6.1. Global population status - update of IUCN Red List for ACAP species AC6 Doc 30 reports that no changes occurred to the threat status of ACAP species in the 2011 revision of the IUCN Red List, and thus since the previous report on this topic to AC5. However, a detailed re-evaluation of the status of the Black-footed Albatross was suspended because some key data had been unavailable by the deadline. The Working Groups note that the next revision of the IUCN Red List, in 2012, would be the major quadrennial review of all species. BirdLife International advised that it would wish to work closely with the ACAP Secretariat to undertake the re-evaluation of ACAP species, based on the data available in the ACAP database.
