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
Regent Honeyeater Anthochaera phrygia	CR	breeding	1995-2008	2-12 individuals	A1
Diamond Firetail Stagonopleura guttata	VU	resident	2005-2008	frequent	A1

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

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.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	poor (40-69%)	moderate (70-90%)	very unfavourable
Shrubland	poor (40-69%)	moderate (70-90%)	very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	happening now	whole area/population (>90%)	moderate to rapid deterioration	very high
Agricultural expansion and intensification	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Human intrusions and disturbance	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	past (and unlikely to return) and no longer limiting	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
Little/none of site covered (<10%)	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	Very little or no conservation action taking place	low

Habitat1	Habitat detail	% of IBA
Artificial/Terrestrial	Improved grassland & pasture	major (>10)
Forest	Callitris forests & woodlands, Casuarina forests & woodlands, Eucalypt woodlands	major (>10)
Shrubland	Mallee shrublands & woodlands	minor (<10)

1. IUCN Habitat classification.

Land use	% of IBA
rangeland/pastureland	major (>10)
forestry	minor (<10)
nature conservation and research	minor (<10)

The IBA is owned by a handful of large private land-owners (50,608ha), with an additional 13,376ha in State Forest (Durikai SF, McIntyre SF).
