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 |
|---|---|---|---|---|
| Mrs Hume's Pheasant Syrmaticus humiae | VU | resident (2004) | present | A3 |
| Scaly-sided Merganser Mergus squamatus | EN | winter (2003) | present | A1 |
| Red-crested Pochard Netta rufina | LC | non-breeding (2003) | min 10,000 birds | A4i |
| Gadwall Mareca strepera | LC | non-breeding (2003) | present | A4i |
| Indian Spot-billed Duck Anas poecilorhyncha | LC | resident (2008) | present | A4i |
| Eurasian Coot Fulica atra | LC | non-breeding (2003) | min 10,000 birds | A4i |
| Yunnan Nuthatch Sitta yunnanensis | LC | resident (2000) | present | A2, A3 |
| Giant Nuthatch Sitta magna | EN | resident (2003) | present | A1, A3 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2008) is shown below.
