Grand Sud Marin


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
White-winged Petrel Pterodroma leucoptera VU breeding 2004-2007 5,000-18,000 breeding pairs A1, A4ii
Tahiti Petrel Pseudobulweria rostrata NT breeding 2012 50-249 breeding pairs A1

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 favourable high negligible
Whole site assessed? State assessed by Accuracy of information
yes habitat poor

State (condition of the trigger species' habitats)
Habitat Quantity (% remaining) Quality (% carrying capacity) Result
Marine Neritic good (> 90%) good (> 90%) favourable

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Biological resource use happening now some of area/population (10-49%) slow but significant deterioration medium
Pollution happening now majority/most of area/population (50-90%) no or imperceptible deterioration low
Climate change and severe weather likely in long term (beyond 4 years) whole area/population (>90%) no or imperceptible deterioration low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas Management plan Other action Result
Little/none of site covered (<10%) No management planning has taken place Very little or no conservation action taking place negligible
