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
Whooper Swan Cygnus cygnus	LC	passage (1996)	101–500 birds	B1i, C2
Bean Goose Anser fabalis	LC	passage (1996)	500–2,000 birds	B1i, C3
Corncrake Crex crex	LC	breeding (1996)	6–10 pairs	B2, C6
Spotted Crake Porzana porzana	LC	breeding (1996)	51–100 pairs	B3, C2, C6
Common Crane Grus grus	LC	breeding (1996)	51–100 pairs	B1i, B2, C2, C6
Common Crane Grus grus	LC	passage (1996)	700–1,500 birds	B1i, C2

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2010) is shown below.

State (condition of the trigger species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Bean Goose Anser fabalis	400 / 800 (birds)	50	poor
Spotted Crake Porzana porzana	7 / 50 (pairs)	15	very poor

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Energy production and mining	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Pollution	happe­ning now	most of popul­ation/area (50–90%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Most of area (50–90%) covered (including the most critical parts for important bird species)	A management plan exists, but it is out of date or not compre­hensive	Some limited conservation initiatives are in place	low

Year	Protected Area	Designation (management category)	% coverage of IBA
1990	Torronsuon kansallispuisto	Kansallispuisto (II)	53

Habitat	% of IBA	Habitat detail
Wetlands (inland)	65	Standing freshwater; Raised bogs
Artificial/Terrestrial	35

Land use	% of IBA
