The site was identified as internationally important for bird conservation in 2020 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
Magellanic Plover Pluvianellus socialis	VU	breeding (2016–2020)	85–180 birds	A4, B1a, B3a, B3b
Two-banded Plover Charadrius falklandicus	LC	breeding (2016–2020)	800 birds	B3b
Hudsonian Godwit Limosa haemastica	VU	winter (2008)	4,500–10,500 birds	A4i
Hudsonian Godwit Limosa haemastica	VU	non-breeding (2016–2020)	750–20,000 birds	A4, B3a, B3b
Red Knot Calidris canutus	NT	winter (2008)	13,000 birds	A4i
Red Knot Calidris canutus	NT	non-breeding (2016–2020)	1,185–10,900 birds	A4, B1a, B3a, B3b
White-rumped Sandpiper Calidris fuscicollis	VU	non-breeding (2016–2020)	320–6,550 birds	B3b
A4iii Species group - waterbirds	n/a	winter (2008)	20,000-49,999 birds	A4iii

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2020. The most recent assessment (2015) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Marine Intertidal	-	moderate (70–90%)	moderate
Grassland	-	moderate (70–90%)	moderate

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	happe­ning now	most of popul­ation/area (50–90%)	slow decline (1–10% over 3 gener­ations)	high
Energy production and mining	likely in short term (<4 years)	some of popul­ation/area (10–49%)	moderate decline (10–30% over 3 gener­ations)	medium
Pollution	likely in short term (<4 years)	some of popul­ation/area (10–49%)	moderate decline (10–30% over 3 gener­ations)	medium
Invasive and other problematic species and genes	happe­ning now	few indivi­duals/small area (<10%)	moderate decline (10–30% over 3 gener­ations)	low

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	The conservation measures needed for the site are being compre­hensively and effectively implemented	high
