JP007
Lakes Komuke and Shibunotsunai


IBA Justification

The site was identified as internationally important for bird conservation in 2004 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
Eurasian Wigeon Mareca penelope LC passage (2003) present A4i
Northern Pintail Anas acuta LC passage (2003) present A4i
Whimbrel Numenius phaeopus LC passage (2003) present A4i
Red-necked Stint Calidris ruficollis NT passage (2003) present A4i

IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2015) is shown below.

State (condition of the trigger species' habitats)
Habitat Quantity (% remaining) Quality (% carrying capacity) Result
Marine Coastal/Supratidal good (>90%) poor (40–69%) poor

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Climate change and severe weather happe­ning now most of popul­ation/area (50–90%) moderate decline (10–30% over 3 gener­ations) high
Invasive and other problematic species and genes happe­ning now most of popul­ation/area (50–90%) moderate decline (10–30% over 3 gener­ations) high
Pollution happe­ning now most of popul­ation/area (50–90%) moderate decline (10–30% over 3 gener­ations) high
Human intrusions and disturbance happe­ning now most of popul­ation/area (50–90%) slow decline (1–10% over 3 gener­ations) high
Transportation and service corridors happe­ning now some of popul­ation/area (10–49%) moderate decline (10–30% over 3 gener­ations) high
Agricultural expansion and intensification happe­ning now most of popul­ation/area (50–90%) no or slight decline (<1% over 3 gener­ations) low
Energy production and mining likely in short term (<4 years) few indivi­duals/small area (<10%) 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
Little/none of area covered (<10%) No management planning has taken place Some limited conservation initiatives are in place very low
