National Park of American Samoa - Ta'u


IBA Justification

The site was identified as important in 2012 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 List1 Season Year(s) Size IBA criteria
Samoan Fruit-dove Ptilinopus fasciatus LC resident 1986 min 2,000 individuals A2
Tahiti Petrel Pseudobulweria rostrata NT breeding 2002 1,000-2,499 breeding pairs A1, A4ii
Blue-crowned Lorikeet Vini australis LC resident 1986 min 5,200 individuals A2
Polynesian Wattled Honeyeater Foulehaio carunculatus LC resident 1986 min 47,500 individuals A2
Fiji Shrikebill Clytorhynchus vitiensis LC resident 1986 min 6,000 individuals A2
Polynesian Starling Aplonis tabuensis LC resident 1986 min 2,100 individuals A2
Samoan Starling Aplonis atrifusca LC resident 1986 min 10,000 individuals A2

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2012) may differ.


IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2012. The most recent assessment (2012) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2012 not assessed medium low
Whole site assessed? State assessed by Accuracy of information
yes population medium

State (condition of the trigger species' populations)
Species Reference Actual Units % remaining Result
Tahiti Petrel Pseudobulweria rostrata 1,750 1,750 breeding pairs 100 not assessed

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Climate change and severe weather likely in long term (beyond 4 years) whole area/population (>90%) slow but significant deterioration medium
Invasive and other problematic species and genes happening now whole area/population (>90%) no or imperceptible deterioration low
Biological resource use happening now small area/few individuals (<10%) no or imperceptible deterioration low
Pollution happening now some of area/population (10-49%) no or imperceptible deterioration low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas Management plan Other action Result
Most of site (50-90%) covered (including the most critical parts for important bird species) A management plan exists but it is out of date or not comprehensive Very little or no conservation action taking place low
