Hunter Estuary


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
Chestnut Teal Anas castanea LC non-breeding 2001-2005 1,000-1,600 individuals A4i
Straw-necked Ibis Threskiornis spinicollis LC non-breeding 2005-2007 11,856 individuals A4i
Australasian Bittern Botaurus poiciloptilus VU resident 2002-2007 6 individuals A1
Red-necked Avocet Recurvirostra novaehollandiae LC non-breeding 2000-2006 104-4,960 individuals A4i
Far Eastern Curlew Numenius madagascariensis EN non-breeding 2000-2006 383-786 individuals A4i
Sharp-tailed Sandpiper Calidris acuminata VU non-breeding 2002-2007 1,800 individuals A4i
Latham's Snipe Gallinago hardwickii NT non-breeding 1997-2007 7-475 individuals A4i

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 (2019) is shown below.

Year of assessment State Pressure Response
2019 near favourable medium medium
Whole site assessed? State assessed by Accuracy of information
yes habitat -

State (condition of the trigger species' habitats)
Habitat Quantity (% remaining) Quality (% carrying capacity) Result
Marine Coastal/Supratidal moderate (70-90%) good (> 90%) near 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
Natural system modifications happening now some of area/population (10-49%) slow but significant deterioration medium
Transportation and service corridors likely in long term (beyond 4 years) small area/few individuals (<10%) moderate to rapid deterioration low
Invasive and other problematic species and genes happening now small area/few individuals (<10%) slow but significant 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 comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity medium
