IBA Justification

The site was identified as internationally important for bird conservation in 2000 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 List	Season (year/s of estimate)	Size	IBA criteria
Red-breasted Merganser Mergus serrator	LC	non-breeding (-)	2,000 birds	A4i, B1i, C3
Tufted Duck Aythya fuligula	LC	non-breeding (1991)	10,022 birds	B1i, C3
A4iii Species group - waterbirds	n/a	non-breeding (-)	min 20,000 birds	A4iii, C4
