Ashmore Reef

Current view: Data table and detailed info

IBA Justification

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
Lesser Frigatebird Fregata ariel	LC	resident (2001–2006)	2,300 birds	A4ii
Brown Booby Sula leucogaster	LC	resident (2001–2006)	4,800 birds	A4ii
Grey-tailed Tattler Tringa brevipes	LC	non-breeding (1998–2006)	85–1,706 birds	A4i

IBA Conservation

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.

IBA conservation assessment
Year of assessment	State	Pressure	Response
2008	not assessed	high	not assessed
Whole site assessed?	State assessed by	Accuracy of information
yes	unset	good

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	most of population/area (50–90%)	slow decline (1–10% over 3 generations)	high
Human intrusions and disturbance	happening now	most of population/area (50–90%)	slow decline (1–10% over 3 generations)	high
Climate change and severe weather	likely in long term (>4 years)	whole of population/area (>90%)	slow decline (1–10% over 3 generations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
