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 |
|---|---|---|---|---|
| White-winged Duck Asarcornis scutulata | CR | resident (2002) | present | A1 |
| Pale-capped Pigeon Columba punicea | VU | resident (2002) | present | A1 |
| Lesser Adjutant Leptoptilos javanicus | NT | resident (2002) | present | A1 |
| White-bellied Heron Ardea insignis | CR | resident (2004) | present | A1 |
| White-rumped Vulture Gyps bengalensis | CR | non-breeding (2002) | present | A1 |
| Slender-billed Vulture Gyps tenuirostris | CR | non-breeding (2002) | present | A1 |
| Rufous-necked Hornbill Aceros nipalensis | VU | resident (2002) | present | A1 |
| Yellow-vented Warbler Phylloscopus cantator | LC | resident (2002) | present | A2 |
