Data Zone
The site was identified as internationally important for bird conservation in 2007 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 |
|---|---|---|---|---|
| Shy Ground Dove Pampusana stairi | LC | breeding (2004) | common | A1, A2 |
| Many-coloured Fruit-dove Ptilinopus perousii | LC | breeding (2004) | common | A2 |
| Tongan Fruit-dove Ptilinopus porphyraceus | LC | breeding (2004) | common | A2 |
| Tropical Shearwater Puffinus bailloni | LC | breeding (2004) | 1,500 pairs | A4ii |
| Maroon Shining-parrot Prosopeia tabuensis | LC | breeding (2004) | present | A2 |
| Blue-crowned Lorikeet Vini australis | LC | breeding (1990) | uncommon | A2 |
| Polynesian Wattled Honeyeater Foulehaio carunculatus | LC | breeding (2004) | common | A2 |
| Tongan Whistler Pachycephala jacquinoti | NT | breeding (2004) | common | A1, A2 |

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2007) is shown below.

| Invasive and other problematic species and genes | likely in short term (<4 years) | most of population/area (50–90%) | rapid decline (>30% over 3 generations) | high |
| Biological resource use | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
