The site was identified as internationally important for bird conservation in 2011 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 2011. The most recent assessment (2008) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Energy production and mining	happe­ning now	some of popul­ation/area (10–49%)	moderate decline (10–30% over 3 gener­ations)	high
Pollution	happe­ning now	some of popul­ation/area (10–49%)	moderate decline (10–30% over 3 gener­ations)	high
Human intrusions and disturbance	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Agricultural expansion and intensification	happe­ning now	some of popul­ation/area (10–49%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Some of area covered (10–49%)	Not assessed	Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity	low

Year	Protected Area	Designation (management category)	% coverage of IBA
