The site was identified as internationally important for bird conservation in 2007 because it was regularly supporting significant populations of the species listed below, meeting IBA criteria.

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

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Arctic Loon Gavia arctica	LC	breeding (1995)	5 breeding pairs	C6

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2007) is shown below.

Pressure (threats to the key species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	likely in short term (within 4 years)	few individ­uals/small area (<10%)	moderate deteri­oration (10–30% in 3 gener­ations)	low

Response (conservation actions taken for the key species and/or their habitats)
Designation	Planning	Action	Result
Some of site covered (10–49%)	No manage­ment planning has taken place	Very little or no conservation action taking place	very low

Year	Protected Area	Designation (management category)	% coverage of IBA
1975	Loch Stack and River Laxford	Site of Special Scientific Interest (UK) (IV)	33

Habitat	% of IBA	Habitat detail
