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 |
|---|---|---|---|---|
| Copper Pheasant Syrmaticus soemmerringii | NT | resident (2003) | present | A3 |
| Mandarin Duck Aix galericulata | LC | breeding (2003) | present | A3 |
| Latham's Snipe Gallinago hardwickii | NT | breeding (2003) | present | A3 |
| Ashy Minivet Pericrocotus divaricatus | LC | breeding (2003) | present | A3 |
| Narcissus Flycatcher Ficedula narcissina | LC | breeding (2003) | present | A3 |
| Japanese Accentor Prunella rubida | 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.
