IBA Justification

The site was identified as internationally important for bird conservation in 2007 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
Little Tern Sternula albifrons LC breeding (2000) 309 pairs A4i, B1i, B2, C2
Little Tern Sternula albifrons LC breeding (2006) 369 pairs A4i, B1i, B2, C2

IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2007) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2007 good very high medium
Whole site assessed? State assessed by Accuracy of information
yes population good

State (condition of the trigger species' populations)
Species Actual vs Reference (units) % remaining Result
Little Tern Sternula albifrons 369 / 250 (pairs) 100 good

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Human intrusions and disturbance happe­ning now whole of popul­ation/area (>90%) rapid decline (>30% over 3 gener­ations) very high
Natural system modifications likely in short term (<4 years) few indivi­duals/small area (<10%) slow decline (1–10% over 3 gener­ations) low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation Planning Action Result
Whole area (>90%) covered by appropriate conservation designation No management plan exists, but the management planning process has begun The conservation measures needed for the site are being compre­hensively and effectively implemented medium
