FI042
Sundominlahti Bay and Söderfjärden


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
Whooper Swan Cygnus cygnus LC passage (1996) 1,000 birds A4i, B1i, C2
Greylag Goose Anser anser LC passage (1996) 290 birds B1i, C3
Bean Goose Anser fabalis LC passage (1996) 1,500 birds B1i, C3
Common Crane Grus grus LC passage (1996) 2,800 birds A4i, B1i, C2
Little Gull Hydrocoloeus minutus LC breeding (1996) 40 pairs B2

IBA Conservation

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.

IBA conservation assessment
Year of assessment State Pressure Response
2010 poor high low
Whole site assessed? State assessed by Accuracy of information
yes population medium

State (condition of the trigger species' populations)
Species Actual vs Reference (units) % remaining Result
Whooper Swan Cygnus cygnus 750 / 1,000 (birds) 75 moderate
Greylag Goose Anser anser 4,000 / 2,000 (birds) 100 good
Bean Goose Anser fabalis 800 / 1,500 (birds) 54 poor
Common Crane Grus grus 6,500 / 3,000 (birds) 100 good

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Pollution happe­ning now some of popul­ation/area (10–49%) moderate decline (10–30% over 3 gener­ations) high
Human intrusions and disturbance happe­ning now most of popul­ation/area (50–90%) no or slight decline (<1% over 3 gener­ations) low
Natural system modifications happe­ning now some of popul­ation/area (10–49%) 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(50–90%) covered (including the most critical parts for important bird species) A management plan exists, but it is out of date or not compre­hensive Very little or no conservation action taking place low
