1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2016) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2016. The most recent assessment (2018) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Energy production and mining	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Natural system modifications	likely in short term (within 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	likely in long term (beyond 4 years)	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
Whole area of site (>90%) covered by appropriate conservation designation	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	high
