The site was identified as important in 2004 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:

Species	Red List1	Season	Year(s)	Size	IBA criteria
White-tailed Sea-eagle Haliaeetus albicilla	LC	winter	-	15 individuals	C1

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2004) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2013) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
White-tailed Sea-eagle Haliaeetus albicilla	15	0	individuals	0	very unfavourable

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Artificial/Aquatic & Marine	good (> 90%)	very poor (< 40%)	very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Human intrusions and disturbance	past (and unlikely to return) and no longer limiting	majority/most of area/population (50-90%)	no or imperceptible deterioration	low
Biological resource use	past (and unlikely to return) and no longer limiting	some of area/population (10-49%)	no or imperceptible deterioration	low
Residential and commercial development	likely in long term (beyond 4 years)	some of area/population (10-49%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>90%) covered by appropriate conservation designation	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	Very little or no conservation action taking place	medium

Year	Protected Area	Designation	% overlap with IBA
