CSIRO's NESP Marine and Coastal Hub project outputs include hindcast and forecast habitat suitability maps for the endangered Maugean skate in Macquarie Harbour, Tasmania. The project used Close Kin Mark Recapture (CKMR) analysis to estimate spawning stock abundance and modelled habitat distribution using telemetry and biophysical data. Outputs include spatial maps (PNG), a final report (HTML), and DNA sequencing data.
Use Cases
- Modeling population trends based on Close Kin Mark Recapture (CKMR) analysis described in the project.
- Forecasting habitat suitability under different management scenarios based on dissolved oxygen, temperature, and depth variables.
- Identifying critical habitat areas for conservation planning using the generated potential habitat maps.
- Designing future spatial and temporal sampling strategies for the Maugean skate based on modelled distribution outputs.
Strengths
- Focuses on a species with one of the most restricted distributions of any extant elasmobranch, found only in two Tasmanian harbours.
- Provides independent population-assessment methods and hindcast/forecast habitat maps to support conservation decision-making.
- Project addresses a high conservation priority for a small population of ~3,000 individuals exposed to environmental pressures.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
