Highest Coral Cover in 36 years on the Great Barrier Reef

The northern and central Great Barrier Reef have recorded their highest amount of coral cover since the Australian Institute of Marine Science (AIMS) began monitoring 36 years ago. Published today, AIMS’ Annual Summary Report on Coral Reef Condition for 2021/22 shows another year of increased coral cover across much of the Reef.

In the 87 representative reefs surveyed between August 2021 and May 2022 under the AIMS Long-Term Monitoring Program (LTMP), average hard coral cover in the region north of Cooktown increased to 36% (from 27% in 2021) and to 33% in the central Great Barrier Reef (from 26% in 2021). However, average coral cover in the southern region (from Proserpine to Gladstone) decreased from 38% in 2021 to 34%.
