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	1980-2008	uncommon	A1
Yellow-faced Honeyeater Caligavis chrysops	LC	passage	2006	200,000 individuals	A4ii
Pilotbird Pycnoptilus floccosus	VU	breeding	1980-2008	common	A2
Rockwarbler Origma solitaria	LC	breeding	1980-2008	common	A2, A3
Flame Robin Petroica phoenicea	LC	breeding	1980-2008	uncommon	A1
Diamond Firetail Stagonopleura guttata	VU	breeding	1998-2008	uncommon	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	good (> 90%)	good (> 90%)	favourable
Rocky areas (eg. inland cliffs, mountain peaks)	good (> 90%)	good (> 90%)	favourable
Shrubland	good (> 90%)	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Invasive and other problematic species and genes	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Natural system modifications	likely in short term (within 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Geological events	likely in long term (beyond 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Residential and commercial development	likely in short term (within 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low
Transportation and service corridors	likely in short term (within 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low
Pollution	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Energy production and mining	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
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	Some limited conservation initiatives are in place	not assessed

Year	Protected Area	Designation	% overlap with IBA
2000	Greater Blue Mountains Area	World Heritage Site (natural or mixed)	100
2006	Gardens of Stone	National Park	1
2010	Kanangra-Boyd	National Park	7
2011	Nattai	National Park	5
2015	Wollemi	National Park	47
2015	Blue Mountains	National Park	25
2015	Yengo	National Park	14
