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 |
|---|---|---|---|---|
| Bar-headed Goose Anser indicus | LC | non-breeding (2002) | present | A4i |
| Greylag Goose Anser anser | LC | non-breeding (2002) | present | A4i |
| Baer's Pochard Aythya baeri | CR | winter (2002) | present | A1 |
| Greater Adjutant Leptoptilos dubius | NT | breeding (2002) | present | A1 |
