| Summary | We use coral cover as a proxy for coral reef biodiversity, which in turn is a proxy for the overall health of biodiversity of the Great Barrier Reef system. |

| Commons Renewability | Renewable (1) |
|---|
| Explanation | But takes decades to renew because coral reefs are slow-growing |
|---|

| Commons Accessibility | Somewhat accessible (2) |
|---|
| Explanation | Boats are required to get to the reef. Some areas near shore are more accessible than offshore reefs. |
|---|
| Commons Heterogeneity | High (3) |
|---|
| Explanation | Corals cluster together in reefs, in a patchwork of reef and non-reef areas. |

| Commons Spatial Extent | 345000 |

| Explanation | Coral makes up 7% but is found across north-south and inshore-offshore components of the GBRMP. |

| Technical Substitute | No |
|---|
| Explanation | Can get artificial reef structures, but can't substitute coral |
