                          Macquarie Island hosts the other two species of albatrosses.  All of these populations are very small and are critical for maintaining the genetic diversity necessary to ensure the viability of these species.  Although these populations are likely to be genetically distinct (based on data from other populations which have been studied), no data currently exist regarding the genetic distinctiveness of these populations.

                          Criteria (d).  Whether the habitat is necessary to maintain genetic diversity and long-term evolutionary development
                          If these island habitats were lost, it is unlikely that the species which use them would persist.  Albatrosses are extremely site-faithful and the populations currently breeding on these islands are unlikely to breed elsewhere.

                          Criteria (e).  Whether the habitat is necessary for use as corridors to allow the species to move freely between sites used to meet essential life cycle requirements.
                          N/A.

                          Criteria (f).  Whether the habitat is necessary to ensure the long-term future of the species or ecological community through reintroduction or re-colonisation.
                          Shy albatrosses occupy most of the land area of the islands on which they breed.

                          Wandering and Grey-headed Albatrosses do not breed on all parts of Macquarie Island, but the entire island is critical to providing isolation for each population and protection from the impact of disturbance.  Some of these populations are also recovering from past declines and hence expanding, hence the whole island is considered critical to their survival and future growth.

                          Macquarie Island is also subject to feral animal control, with an intensive control campaign focussed on the eradiation of feral cats from the island.

                          Criteria (g).  Any other way in which habitat may be critical to the survival of a listed threatened species or a listed threatened ecological community.
                          N/A.

Thalassarche chrysostoma (Grey-headed Albatross) – Macquarie Island

Listed Critical Habitat:  Thalassarche chrysostoma (Grey-headed Albatross) – Macquarie Island

Date Effective:           01 July 2002
Location and extent:      Macquarie Island:  About 13,000 ha, comprising all islands and rocks above mean high water level, lying within the area bounded by parallels 54°27' S and 54°49' S latitude and meridian.

Reasons for listing:      Criteria (a). Whether the habitat is used during periods of stress.  Examples of period of stress: Flood, drought or fire.
                          N/A

                          Criteria (b).  Whether the habitat is used to meet essential life cycle requirements.  Examples: Foraging, breeding, nesting, roosting, social behaviour patterns or seed dispersal processes.
                          All albatrosses spend more than 95% of their time traversing the world's oceans in search of prey, and usually only return to land to breed.  For southern hemisphere species, nesting
