Lehua Islet


IBA Justification

The site was identified as important in 2009 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
Red-tailed Tropicbird Phaethon rubricauda LC breeding 2002 200 nests A4ii
Black-footed Albatross Phoebastria nigripes NT breeding 2005 16 nests A1

IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2009) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2009 not assessed high low
Whole site assessed? State assessed by Accuracy of information
yes unset medium

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Invasive and other problematic species and genes happening now whole area/population (>90%) slow but significant deterioration high
Human intrusions and disturbance happening now small area/few individuals (<10%) no or imperceptible deterioration low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas Management plan Other action Result
Whole area of site (>90%) covered by appropriate conservation designation Unknown Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity low
