Anson Bay, Daly and Reynolds River Floodplains


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
Magpie Goose Anseranas semipalmata LC resident 1984-1991 50,000-332,000 individuals A4i
Wandering Whistling-duck Dendrocygna arcuata LC non-breeding 1990-2000 40,000 individuals A4i
Pied Heron Egretta picata LC resident 1990-2000 2,500 individuals A4i
Bush Thick-knee Burhinus grallarius LC resident 1998-2008 uncommon A1
Great Knot Calidris tenuirostris EN non-breeding 1990-2002 5,000 individuals A4i
Varied Lorikeet Psitteuteles versicolor LC resident 1998-2008 uncommon A3
Rainbow Pitta Pitta iris LC resident 1998-2008 frequent A2, A3
Silver-crowned Friarbird Philemon argenticeps LC resident 1998-2008 uncommon A3
Bar-breasted Honeyeater Ramsayornis fasciatus LC resident 1998-2008 uncommon A3
White-gaped Honeyeater Stomiopera unicolor LC resident 1998-2008 common A3
Australian Yellow White-eye Zosterops luteus LC resident 1998-2008 uncommon 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 (2016) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2016 near favourable high low
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
Wetlands (inland) good (> 90%) moderate (70-90%) near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Agricultural expansion and intensification happening now some of area/population (10-49%) moderate to rapid deterioration high
Energy production and mining likely in long term (beyond 4 years) whole area/population (>90%) moderate to rapid deterioration high
Invasive and other problematic species and genes happening now majority/most of area/population (50-90%) slow but significant deterioration high
Climate change and severe weather likely in long term (beyond 4 years) some of area/population (10-49%) moderate to rapid deterioration medium
Pollution happening now some of area/population (10-49%) slow but significant deterioration medium
Human intrusions and disturbance happening now small area/few individuals (<10%) slow but significant deterioration low
Residential and commercial development happening now small area/few individuals (<10%) no or imperceptible deterioration low
Transportation and service corridors happening now small area/few individuals (<10%) no or imperceptible deterioration low
Natural system modifications happening now majority/most of area/population (50-90%) 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 plan exists but the management planning process has begun Some limited conservation initiatives are in place low
