1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2011) may differ.

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
Transportation and service corridors	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Human intrusions and disturbance	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Invasive and other problematic species and genes	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Pollution	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Some of site covered (10-49%)	Not assessed	Not assessed	negligible
