1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2010) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2019) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Transportation and service corridors	likely in short term (within 4 years)	whole area/population (>90%)	very rapid to severe deterioration	very high
Energy production and mining	happening now	majority/most of area/population (50-90%)	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
