1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2018) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2018. The most recent assessment (1990) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Energy production and mining	happening now	majority/most of area/population (50-90%)	very rapid to severe deterioration	very high
Transportation and service corridors	happening now	majority/most of area/population (50-90%)	very rapid to severe deterioration	very high
Biological resource use	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Pollution	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Climate change and severe weather	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Agricultural expansion and intensification	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Residential and commercial development	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Natural system modifications	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
