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 (2012) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2012 good medium very low
Whole site assessed? State assessed by Accuracy of information
yes population poor

State (condition of the trigger species' populations)
Species Actual vs Reference (units) % remaining Result
Black Noddy Anous minutus 7,500 / 6,000 (pairs) 100 good

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Climate change and severe weather likely in long term (>4 years) whole of popul­ation/area (>90%) slow decline (1–10% over 3 gener­ations) medium
Invasive and other problematic species and genes happe­ning now whole of popul­ation/area (>90%) no or slight decline (<1% over 3 gener­ations) low
Biological resource use happe­ning now some of popul­ation/area (10–49%) no or slight decline (<1% over 3 gener­ations) low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation Planning Action Result
Little/none of area covered (<10%) No management planning has taken place Some limited conservation initiatives are in place very low
