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
Albert's Lyrebird Menura alberti	LC	resident	1980-2008	frequent	A1, A2, A3
Green Catbird Ailuroedus crassirostris	LC	resident	1980-2008	common	A2, A3
Regent Bowerbird Sericulus chrysocephalus	LC	resident	1980-2008	common	A2, A3
Australian Logrunner Orthonyx temminckii	LC	resident	1980-2008	common	A3
Paradise Riflebird Lophorina paradisea	LC	resident	1980-2008	common	A2, A3
Pale-yellow Robin Tregellasia capito	LC	resident	1980-2008	common	A2

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 (2020) is shown below.

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Natural system modifications	happening now	some of area/population (10-49%)	slow but significant deterioration	medium

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	Unknown	low

Year	Protected Area	Designation	% overlap with IBA
1986	Gondwana Rainforests of Australia	World Heritage Site (natural or mixed)	31
1992	Snows Gully	Nature Reserve	<1
1999	Nightcap	National Park	51
2003	Whian Whian	State Conservation Area	16
2012	Goonengerry	National Park	3
2014	Mount Jerusalem	National Park	33
