Data Zone
The site was identified as internationally important for bird conservation in 2009 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 |
|---|---|---|---|---|
| Chestnut Rail Eulabeornis castaneoventris | LC | resident (2008) | frequent | A2 |
| Far Eastern Curlew Numenius madagascariensis | EN | non-breeding (1990–2007) | 77–407 birds | A4i |
| Sharp-tailed Sandpiper Calidris acuminata | VU | non-breeding (1990–2007) | 782–1,841 birds | A4i |
| Grey-tailed Tattler Tringa brevipes | LC | non-breeding (1990–2007) | 113–1,786 birds | A4i |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2019) is shown below.
