The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2010).

Pressure (threats to the trigger species and/or their habitats)
Threat level 1	Threat level 2	Timing	Scope	Severity	Result
Energy production and mining	renewable energy	likely in short term (within 4 years)	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Human intrusions and disturbance	recreational activities	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Invasive and other problematic species and genes	invasive non-native/alien species/diseases - unspecified species	happening now	whole area/population (>90%)	slow but significant deterioration	high
Transportation and service corridors	shipping lanes	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Transportation and service corridors	shipping lanes	likely in short term (within 4 years)	majority/most of area/population (50-90%)	very rapid to severe deterioration	high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation	Management planning	Other conservation action	Result
Most of site (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
