Barrow Island


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
Pied Oystercatcher Haematopus longirostris LC non-breeding 2003-2004 112-362 individuals A4i
Red-necked Stint Calidris ruficollis NT non-breeding 2003-2004 822-7,611 individuals A4i
Grey-tailed Tattler Tringa brevipes LC non-breeding 2003-2004 429-2,634 individuals A4i
Fairy Tern Sternula nereis VU non-breeding 2003-2004 41-1,060 individuals A1, A4i
Spinifexbird Poodytes carteri LC resident 1978-2004 17,800-24,600 individuals A3

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2009) may differ.


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 (2018) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2018 favourable medium high
Whole site assessed? State assessed by Accuracy of information
yes habitat medium

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

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Residential and commercial development likely in long term (beyond 4 years) some of area/population (10-49%) moderate to rapid deterioration medium
Energy production and mining happening now small area/few individuals (<10%) slow but significant deterioration low
Invasive and other problematic species and genes happening now small area/few individuals (<10%) no or imperceptible deterioration low
Human intrusions and disturbance happening now small area/few individuals (<10%) no or imperceptible deterioration low
Natural system modifications 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 A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species The conservation measures needed for the site are being comprehensively and effectively implemented high
