The site was identified as internationally important for bird conservation 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 List	Season (year/s of estimate)	Size	IBA criteria
Rufous Scrub-bird Atrichornis rufescens	EN	resident (1980–2008)	uncommon	A1, A2, A3
Green Catbird Ailuroedus crassirostris	LC	resident (1980–2008)	frequent	A2, A3
Regent Bowerbird Sericulus chrysocephalus	LC	resident (1980–2008)	uncommon	A2, A3
Australian Logrunner Orthonyx temminckii	LC	resident (1980–2008)	uncommon	A3
Paradise Riflebird Lophorina paradisea	LC	resident (1980–2008)	uncommon	A2, A3
Flame Robin Petroica phoenicea	LC	breeding (1980–2008)	frequent	A1
Pale-yellow Robin Tregellasia capito	LC	resident (1980–2008)	uncommon	A2

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%)	good

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	happe­ning now	whole of popul­ation/area (>90%)	moderate decline (10–30% over 3 gener­ations)	very high

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>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	Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity	high

Year	Protected Area	Designation (management category)	% coverage of IBA
1986	Gondwana Rainforests of Australia	World Heritage Site (natural or mixed) (UA)	31
1986	Paddys Brush	Flora Reserve (Ia)	<1
1999	Mount Royal	National Park (II)	5
1999	Mount Allyn	Flora Reserve (Ia)	2

2003	Barrington Tops	State Conservation Area (II)	7
2007	Mount Royal	Conservation Area (VI)	<1
2010	Barrington Tops	National Park (Ib)	58

Habitat	% of IBA	Habitat detail
Forest	major (>10)	Eucalypt tall open forests; Rainforest & vine thickets
Savanna	major (>10)	Eucalypt open woodlands
Grassland	minor (<10)	Tussock grasslands
Wetlands (inland)	minor (<10)	Montane bogs, swamps & mires
