Australian Ocean Data Network hosts data from a pilot management program to maximize Tasmania's Sea Urchin resource. The research aimed to determine the potential for reducing urchin density to encourage seaweed return and improve urchin roe quality and quantity. Data was collected at Hope Island, including an initial survey before the main study.
Use Cases
- Modeling the relationship between urchin density and seaweed recovery based on controlled clearing experiments.
- Analyzing changes in urchin roe quality and quantity following density manipulations.
- Assessing the ecological impact of overgrazing in subtidal barrens areas.
Strengths
- Data originates from a structured experimental program with controlled density manipulations.
- Includes results from an initial survey collected before the main study commenced.
- Associated files are available in multiple formats including XLS and PDF.
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 Tasmanian study sites.
