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

State (condition of the trigger species' habitats)
Habitat Quantity (% remaining) Quality (% carrying capacity) Result
Marine Neritic good (>90%) good (>90%) good

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Biological resource use happe­ning now some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium
Pollution happe­ning now most of popul­ation/area (50–90%) 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
Some of area covered (10–49%) No management planning has taken place Very little or no conservation action taking place very low
