Posidonia Seagrass Fragment Health and Abundance in Botany Bay

Beachcast fragments of Posidonia australis seagrass were collected at seven sites in Gamay (Botany Bay), Australia. The dataset captures fragment abundance, collection dates, environmental conditions, and shoot necrosis proportions to inform restoration efforts. It was published by the Australian Ocean Data Network and last updated in June 2026.

Use Cases

• Identify optimal collection sites for restoration material based on fragment abundance data.
• Model the influence of wind speed and direction on fragment availability for collection planning.
• Assess fragment health for restoration viability based on observed necrosis proportions.
• Correlate tidal height and swell conditions with the quantity of beachcast material.

Strengths

• Data covers seven distinct collection sites within Botany Bay.
• Includes measurements for multiple environmental variables: wind speed, wind direction, tidal height, swell height, and swell direction.
• Separate data sheets for fragment counts and shoot health observations.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
