Data Zone
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 |
|---|---|---|---|---|
| Japanese Cormorant Phalacrocorax capillatus | LC | breeding (2003) | present | A4i |
| Slaty-backed Gull Larus schistisagus | LC | breeding (2003) | present | A4i |
| Blakiston's Eagle-owl Bubo blakistoni | EN | resident (2003) | present | A1, A3 |
| Steller's Sea-eagle Haliaeetus pelagicus | VU | winter (2003) | present | A1 |
| Middendorff's Grasshopper-warbler Helopsaltes ochotensis | LC | breeding (2003) | present | A3 |
| Kamchatka Leaf-warbler Phylloscopus examinandus | LC | breeding (2003) | present | A3 |
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.
