IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2012. The most recent assessment (2012) is shown below.

IBA conservation assessment
Year of assessment	State	Pressure	Response
2012	good	low	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
Pollution	happening now	some of population/area (10–49%)	no or slight decline (<1% over 3 generations)	low
Climate change and severe weather	likely in long term (>4 years)	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	Very little or no conservation action taking place	very low
