1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2001) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2019) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Pollution	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Energy production and mining	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Biological resource use	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Transportation and service corridors	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Agricultural expansion and intensification	likely in short term (within 4 years)	majority/most of area/population (50-90%)	no or imperceptible deterioration	low
Residential and commercial development	happening now	some of area/population (10-49%)	no or imperceptible deterioration	low
Human intrusions and disturbance	happening now	majority/most of area/population (50-90%)	no or imperceptible deterioration	low

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
