Coral Reef Restoration Experiments on Magnetic Island 2018-2020

Magnetic Island, Queensland, Australia, was the site for macroalgae removal and coral larval seeding experiments from 2018 to 2020. The dataset includes fish survey data, photo quadrats, coral recruitment counts, and macroalgae measurements from 24 permanent 5x5m plots across two bays. Data was collected by the Australian Ocean Data Network as part of the NESP TWQ 4.3 project.

Use Cases

• Assessing the impact of macroalgae removal on fish communities based on stationary point count survey data.
• Analyzing coral recruitment success to settlement tiles under different experimental treatments.
• Monitoring changes in reef benthic composition over time based on 1650 photo quadrats.
• Evaluating the combined effect of algal removal and larval seeding on coral recruit morphology and size classes.

Strengths

• Experimental design includes 24 permanent plots with control, removal-only, seeding-only, and combined treatment groups.
• Data collection spans multiple methods: fish surveys, photo quadrats (1650 images), coral recruitment counts, and macroalgae biomass measurements.
• Temporal coverage includes a baseline survey and multiple monitoring events from 2018 to 2020.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the two specific bays studied on Magnetic Island.
