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)|
|Was the whole site assessed?||State assessed by||Accuracy of information|
|State (condition of the trigger species' populations)|
|Scientific name||Common name||Reference population||Actual population||Units||% of population remaining||Result|
|Megapodius layardi||Vanuatu Scrubfowl||150||100||nests||67||unfavourable|
|Ardenna pacifica||Wedge-tailed Shearwater||10000||10000||nests||100||favourable|
|Pressure (threats to the trigger species and/or their habitats)|
|Threat level 1||Threat level 2||Timing||Scope||Severity||Result|
|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|
|Response (conservation actions taken for the trigger species and/or their habitats)|
|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|
