The site was identified as important in 2001 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
Long-tailed Duck Clangula hyemalis	VU	passage	1988-1995	837,000 individuals	A4i, B1i, C3
Velvet Scoter Melanitta fusca	VU	passage	1992-1995	240,000 individuals	A4i, B1i, C3

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2001) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2015) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Long-tailed Duck Clangula hyemalis	68,000	8,000	individuals	12	very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Energy production and mining	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Human intrusions and disturbance	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Little/none of site covered (<10%)	No management planning has taken place	Very little or no conservation action taking place	negligible
