Cattle and sheep were eradicated from Campbell Island by 1984 and 1992 respectively7. Introduced brown rats Rattus norvegicus have been successfully removed from Campbell Island, although their effect on the colony was never studied7. All islands are nature reserves and part of a World Heritage Site designated in 1998. Conservation Actions Proposed
Census a sample of Antipodes Island colonies every five years, and re-photograph photopoints from 1978 and 1995 expeditions. Census Proclamation Island (Bounty Islands) every five years. Compare aerial and ground surveys of the Bounty Islands to ascertain the viability of using the former method for monitoring colonies7. Conduct detailed studies to determine foraging ranges, commercial fisheries competition, and oceanographic or climatic changes3.
