Management Concern: Moderate    

Adequacy of Information: Low

Summary extracts from Outlook Report 2009

• Little is known of the status of the Halimeda banks that occur in the northern Great Barrier Reef but they are believed to be in very good condition.
• Trawling has the potential to cause habitat damage if not appropriately managed. Since the rezoning of the Great Barrier Reef Marine Park in 2004, trawling is allowed in 34 per cent of the Great Barrier Reef Region; however, it takes places in only about 6 per cent of this area each year.
• Halimeda is a calcareous green alga and is likely to be affected by ocean acidification.
