1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2006) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2006. The most recent assessment (2006) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Biological resource use	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Agricultural expansion and intensification	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Invasive and other problematic species and genes	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Human intrusions and disturbance	happening now	small area/few individuals (<10%)	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	The conservation measures needed for the site are being comprehensively and effectively implemented	high
