Data Zone
The site was identified as internationally important for bird conservation in 2001 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 |
|---|---|---|---|---|
| Black Partridge Melanoperdix niger | VU | resident (2000) | present | A1, A3 |
| Malay Crestless Fireback Lophura erythrophthalma | CR | resident (2000) | present | A1, A3 |
| White-winged Duck Asarcornis scutulata | CR | resident (2000) | present | A1 |
| Lesser Adjutant Leptoptilos javanicus | NT | resident (2000) | present | A1 |
| Storm's Stork Ciconia stormi | EN | resident (2000) | present | A1, A3 |
| Malay Blue-banded Kingfisher Alcedo peninsulae | NT | resident (2000) | present | A1, A3 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2012) is shown below.

| Threat | Timing | Scope | Severity | Result |
| Biological resource use | happening now | some of population/area (10–49%) | 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 |
| Energy production and mining | past (and unlikely to return) and no longer limiting | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | low |
| Human intrusions and disturbance | past (and unlikely to return) and no longer limiting | few individuals/small area (<10%) | no or slight decline (<1% over 3 generations) | low |

|---|---|---|---|
| Designation | Planning | Action | Result |
| Whole area (>90%) covered by appropriate conservation designation | A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species | Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity | high |
