Formatted abstract
Long-term monitoring data show that hard coral cover on the Great Barrier Reef (GBR) has reduced by [70 %over the past century. Although authorities and many marine scientists were in denial for many years, it is now widely accepted that this reduction is largely attributable to the chronic state of eutrophication that exists throughout most of the GBR. Some reefs in the far northern GBR where the annual mean chlorophyll a (Chl a) is in the lower range of the proposed Eutrophication Threshold Concentration for Chl a (~0.2–0.3 mg m-3) show little or no evidence of degradation over the past century. However, the available evidence suggests that coral diseases and the crown-ofthorns starfish will proliferate in such waters and hence the mandated eutrophication Trigger values for Chl a (~0.4–0.45 mg m-3) will need to be decreased to ~0.2 mg m-3 for sustaining coral reef communities.
