The Agreement on the Conservation of Albatrosses and Petrels

We strive, through our 13 Parties, to conserve albatrosses and petrels by coordinating international activities to mitigate threats to their populations.  In 2019 ACAP’s Advisory Committee declared that a conservation crisis continues to be faced by its 31 listed species, with thousands of albatrosses, petrels and shearwaters dying every year as a result of fisheries operations.  To increase awareness of this crisis ACAP inaugurated a World Albatross Day to be held annually on 19 June from 2020, the date the Agreement was signed in 2001.

The Fourteenth Meeting of ACAP’s Advisory Committee (AC14) will be held in Lima, Peru, from 12 to 16 August 2024.

Giganteus Island

Giganteus Island, part of the Rookery Islands in Mac.Robertson Land, East Antarctica is one of the only four known breeding localities for Southern Giant Petrels Macronectes giganteus along the coast of continental Antarctica (i.e away from the Antarctic Peninsula).  The number of occupied nests on the island decreased rapidly from the late 1950s/early 1960s when there were perhaps 15-25 breeding pairs (maximum count 13 eggs in 1962).  There appears to have been an initial marked decrease on Giganteus Island followed by a long period of relative stability: only three occupied nests were recorded in 2007.   The reasons for the historical decrease are uncertain.

The Rookery Islands

The Rookery Islands comprise a group of c. 75 small islands and rocks in Holme Bay, some 10 kilometres west of the Australia’s Antarctic station of Mawson. They are an Antarctic Specially Protected Area (ASPA No. 102) as proclaimed by the Antarctic Treaty System.  Giganteus Island has been designated as a restricted zone within the ASPA to afford a high level of protection to its Southern Giant Petrel population.  Permits to enter the Giganteus Island Restricted Zone during the breeding period (1October to 30 April) may only be issued for the purpose of conducting censuses of the giant petrels.

Inter alia the management plan for the Rookery Islands aims to:

minimise human disturbance to Southern Giant Petrels on Giganteus Island;

allow Giganteus Island to be used as a reference area for future comparative studies with other breeding populations of Southern Giant Petrels; and

preserve Giganteus Island, as a highly-restricted area by limiting human visitation during the Southern Giant Petrel breeding season.

The management plan further states that “where practicable, at least one research visit should be conducted to census [sic] the Southern Giant Petrels at Giganteus Island and other seabird populations in each five year period, to enable assessment of breeding populations.”

Southern Giant Petrels on the Antarctic Continent away from the Antarctic Peninsula comprise less than 1% of the species’ global breeding population.

The last visit made to Giganteus was in December 2008: three pairs and one single giant petrel were sighted.  If possible, the Australian Antarctic Division will try to get a team onto the island in the coming season.
