IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2016) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2016 good medium medium
Whole site assessed? State assessed by Accuracy of information
yes habitat good

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

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Energy production and mining happe­ning now some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation Planning Action Result
Most of area (50–90%) covered (including the most critical parts for important bird species) A compre­hensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity medium
