Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2018) is shown below.

IBA conservation assessment
Year of assessment	State	Pressure	Response
2018	near favourable	medium	negligible
Whole site assessed?	State assessed by	Accuracy of information
yes	habitat	good

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Wetlands (inland)	good (> 90%)	moderate (70-90%)	near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	likely in long term (beyond 4 years)	some of area/population (10-49%)	moderate to rapid deterioration	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Little/none of site covered (<10%)	No management planning has taken place	Very little or no conservation action taking place	negligible
