Motu de l'ouest et du sud de Rangiroa


IBA Justification

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
Polynesian Ground Dove Pampusana erythroptera CR resident (-) 10–12 birds A1, A2
Atoll Fruit-dove Ptilinopus coralensis NT resident (-) common A1, A2
Bristle-thighed Curlew Numenius tahitiensis NT non-breeding (-) min 100 birds A1, A4i
Gygis alba NR breeding (-) 1,000 pairs A4i
Blue Lorikeet Vini peruviana VU resident (2006) 1,249 birds A1, A2
Tuamotu Reed-warbler Acrocephalus atyphus LC resident (-) rare A2

IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2012) is shown below.

State (condition of the trigger species' populations)
Species Actual vs Reference (units) % remaining Result
Polynesian Ground Dove Pampusana erythroptera 11 / 11 (birds) 100 not assessed
Bristle-thighed Curlew Numenius tahitiensis 100 / 100 (birds) 100 not assessed
Gygis alba 1,000 / 1,000 (pairs) 100 not assessed
Blue Lorikeet Vini peruviana 1,249 / 1,249 (birds) 100 not assessed

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Invasive and other problematic species and genes happe­ning now most of popul­ation/area (50–90%) slow decline (1–10% over 3 gener­ations) high
Climate change and severe weather likely in long term (>4 years) whole of popul­ation/area (>90%) slow decline (1–10% over 3 gener­ations) medium
Biological resource use happe­ning now few indivi­duals/small area (<10%) no or slight decline (<1% over 3 gener­ations) low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation Planning Action Result
Little/none of area covered (<10%) No management planning has taken place Some limited conservation initiatives are in place very low
