1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2000) may differ.
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2013) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2013 | unfavourable | very high | low |
| Whole site assessed? | State assessed by | Accuracy of information | |
| yes | habitat | unknown | |

|---|---|---|---|
| Habitat | Quantity (% remaining) | Quality (% carrying capacity) | Result |
| Marine Coastal/Supratidal | good (> 90%) | poor (40-69%) | unfavourable |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Biological resource use | happening now | whole area/population (>90%) | very rapid to severe deterioration | very high |
