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 |
|---|---|---|---|---|
| Spotted Imperial-pigeon Ducula carola | VU | resident (1992) | present | A1 |
| Flame-breasted Fruit-dove Ramphiculus marchei | VU | resident (1992) | present | A1, A2 |
| Furtive Flycatcher Ficedula disposita | LC | resident (1992) | present | A2 |
| Green-faced Parrotfinch Erythrura viridifacies | VU | resident (1992) | present | A1, A2 |
| White-cheeked Bullfinch Pyrrhula leucogenis | LC | resident (1992) | present | A2 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2018) is shown below.
| IBA conservation assessment | |||

| Year of assessment | State | Pressure | Response |
| 2018 | very poor | very high | low |

| Forest | - | poor (40–69%) | very poor |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Energy production and mining | happening now | most of population/area (50–90%) | rapid decline (>30% over 3 generations) | very high |
| Agricultural expansion and intensification | happening now | most of population/area (50–90%) | moderate decline (10–30% over 3 generations) | high |
| Transportation and service corridors | happening now | some of population/area (10–49%) | rapid decline (>30% over 3 generations) | high |
| Invasive and other problematic species and genes | likely in short term (<4 years) | most of population/area (50–90%) | moderate decline (10–30% over 3 generations) | high |
| Biological resource use | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Response (conservation actions taken for the trigger species and/or their habitats) | |||
|---|---|---|---|
| Designation | Planning | Action | Result |
| Some of area covered (10–49%) | A management plan exists, but it is out of date or not comprehensive | Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity | low |
