Data Zone
The site was identified as internationally important for bird conservation in 2004 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.
Populations meeting IBA criteria ('trigger species') at the site:| Species | Red List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| Common Tern Sterna hirundo | LC | breeding (2001) | 250 pairs | C6 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2013) is shown below.
| IBA conservation assessment | |||

| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Invasive and other problematic species and genes | happening now | whole of population/area (>90%) | rapid decline (>30% over 3 generations) | very high |
| Natural system modifications | happening now | most of population/area (50–90%) | rapid decline (>30% over 3 generations) | very high |
| Human intrusions and disturbance | happening now | most of population/area (50–90%) | slow decline (1–10% over 3 generations) | high |

|---|---|---|---|
| Designation | Planning | Action | Result |
| Whole area (>90%) covered by appropriate conservation designation | No management plan exists, but the management planning process has begun | Very little or no conservation action taking place | low |
