The site was identified as internationally important for bird conservation in 2013 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 2013. The most recent assessment (2013) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Pollution	happe­ning now	most of popul­ation/area (50–90%)	moderate decline (10–30% over 3 gener­ations)	high

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Little/none of area covered (<10%)	No management planning has taken place	Not assessed	very low

Habitat	% of IBA	Habitat detail
Artificial/Terrestrial	major (>10)
Shrubland	major (>10)
Grassland	minor (<10)
Wetlands (inland)	minor (<10)

Land use	% of IBA
rangeland/pastureland	major (>10)
agriculture	major (>10)
tourism/recreation	minor (<10)
