The site was identified as important in - because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment (most recent) | State (condition) | Pressure (threat) | Response (action) |
| 2014 | unfavourable | high | negligible |

| Biological resource use | hunting & collecting terrestrial animals - intentional use (species being assessed is the target) | happening now | whole area/population (>90%) | slow but significant deterioration | high |
| Biological resource use | logging & wood harvesting - intentional use: subsistence/small scale | happening now | some of area/population (10-49%) | slow but significant deterioration | medium |

|---|---|---|---|
| Protected-area designation | Management planning | Other conservation action | Result |
| Little/none of site covered (<10%) | No management planning has taken place | Very little or no conservation action taking place | negligible |
