The site was identified as internationally important for bird conservation in 2019 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:

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2019. The most recent assessment (2016) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happe­ning now	whole of popul­ation/area (>90%)	rapid decline (>30% over 3 gener­ations)	very high
Natural system modifications	happe­ning now	whole of popul­ation/area (>90%)	rapid decline (>30% over 3 gener­ations)	very high
Transportation and service corridors	happe­ning now	whole of popul­ation/area (>90%)	moderate decline (10–30% over 3 gener­ations)	very high
Residential and commercial development	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Energy production and mining	likely in long term (>4 years)	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Some of area covered (10–49%)	A management plan exists, but it is out of date or not compre­hensive	Some limited conservation initiatives are in place	low
