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
Natural system modifications	happening now	whole area/population (>90%)	slow but significant deterioration	high
Invasive and other problematic species and genes	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high

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
1961	Waychinicup	National Park	15
1961	Bald Island	Nature Reserve	3
1964	Cheyne Road	Nature Reserve	1
1966	Two Peoples Bay	Nature Reserve	16
1979	Mount Manypeaks	Nature Reserve	5
1980	Arpenteur	Nature Reserve	<1
