Spatially Explicit Current and Future Threats to Australian Seagrass Habitats

A mapped compilation of nation-wide threats to Australian seagrass habitats based on current pressures and projected climate change for 2070. The dataset is a single ArcGIS polygon shapefile composed of 10 x 10 km coastal grid cells, compiled by the Australian Ocean Data Network. It was last updated on 2026-07-13.

Use Cases

• Model cumulative risk to seagrass meadows based on multiple current threat layers.
• Project habitat vulnerability based on modelled sea surface temperature increase for 2070.
• Assess threats to other coastal habitats based on the compiled threat layers.
• Prioritize conservation areas by analyzing spatial overlap of threats like port infrastructure and agricultural runoff.

Strengths

• Covers multiple threat categories, including 7 listed current pressures and 3 modelled future climate pressures.
• Provides spatially explicit data at a 10 x 10 km grid cell resolution for the Australian coastline.
• Includes future projections for key climate variables (sea surface temperature, rainfall, sea level rise) for the year 2070.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last update date is in the future (2026-07-13).
