The site was identified as important in 2007 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
Whooper Swan Cygnus cygnus	LC	winter	1990-1995	595 individuals	B1i, B3, C2, C6
Tundra Swan Cygnus columbianus	LC	winter	1990-1995	600 individuals	A4i, B1i, B2, C2, C6
Pink-footed Goose Anser brachyrhynchus	LC	winter	1990-1995	5,600 individuals	A4i, B1i, C3
Northern Pintail Anas acuta	LC	winter	1990-1995	1,010 individuals	B1i, C3
Ruff Calidris pugnax	LC	winter	2001-2006	128 individuals	C6

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2007) may differ.

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.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Ruff Calidris pugnax	34	128	individuals	100	favourable
A4iii Species group - waterbirds	24,345	4,267	individuals	18	very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
No known threats	happening now	small area/few individuals (<10%)	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	Not assessed	medium
