The site was identified as important in 2009 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

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 (2008) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
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
Not assessed	Not assessed	Not assessed	not assessed

Year	Protected Area	Designation	% overlap with IBA
2005	Lachlan Island	Nature Reserve	<1
2007	Maria Island	National Park	100

Habitat1	Habitat detail	% of IBA
Forest	Eucalypt open forests, Eucalypt tall open forests, Eucalypt woodlands	100
Shrubland	Heath	minor (<10)
Wetlands (inland)	Salt marshes	minor (<10)

1. IUCN Habitat classification.

Land use	% of IBA
nature conservation and research	major (>10)
tourism/recreation	minor (<10)
