Status of sea birds

Management Concern: Moderate    

Adequacy of Information: Moderate

Summary extracts from Outlook Report 2009

  • Twenty-two species of seabird breed on the Great Barrier Reef with serious declines in some populations.
  • Recently, seabird numbers have declined seriously at the four most important seabird breeding sites in the Great Barrier Reef, with no evidence that the birds have moved to other breeding sites in the Great Barrier Reef.  One suggested cause of the declines is poor breeding success linked to changes in the distribution of pelagic fish, the main food source for many species.  These fish distributions may be changing because of warmer sea temperatures linked to climate change.
  • Increasing coastal development is resulting in the loss of both coastal habitats that support the Great Barrier Reef and connectivity between habitats.
  • Much of the research activity on the Great Barrier Reef is confined to areas surrounding the six island research stations. With ongoing management, any impacts of research are likely to be small and localised in the immediate area of study.
