Amphibolis Griffithii Seagrass Recovery Data from Light Reduction Experiment

Parks Australia provides data from a large-scale manipulative experiment examining the recovery of Amphibolis griffithii seagrass meadows after light reduction. The experiment mimicked dredging impacts using shade cloth to test different intensities, durations, and start times of light stress. The dataset was published via the Australian Marine Parks Science Atlas and was last updated in July 2026.

Use Cases

• Modeling seagrass recovery thresholds based on light reduction intensity and duration described in the experiment.
• Identifying potential indicators of recovery from light stress as recommended by the study.
• Assessing the impact of dredging operations on temperate Australian seagrass meadows based on the simulated scenarios.
• Comparing recovery rates of Amphibolis griffithii with other large seagrass species using the reported biomass loss and recovery time data.

Strengths

• The experiment was large-scale and manipulative, directly testing recovery from light stress.
• Specific recovery thresholds were identified, such as recovery after 3 months of stress with up to 72% leaf biomass loss.
• Five potential indicators of recovery were recommended, providing actionable insights for management.

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 data_gov_au, focusing on Australian Marine Parks.
