Data Zone
The site was identified as internationally important for bird conservation in 2003 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 |
|---|---|---|---|---|
| Spot-billed Pelican Pelecanus philippensis | NT | non-breeding (2002) | common | A1 |
| Whiskered Tern Chlidonias hybrida | LC | non-breeding (2002) | abundant | A4i |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2003. The most recent assessment (2009) is shown below.
| IBA conservation assessment | |||

| Year of assessment | State | Pressure | Response |

|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Biological resource use | happening now | most of population/area (50–90%) | moderate decline (10–30% over 3 generations) | high |
| Residential and commercial development | likely in long term (>4 years) | whole of population/area (>90%) | rapid decline (>30% over 3 generations) | high |
| Agricultural expansion and intensification | happening now | few individuals/small area (<10%) | no or slight decline (<1% over 3 generations) | low |
| Pollution | happening now | few individuals/small area (<10%) | no or slight decline (<1% over 3 generations) | low |
