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 (2009) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Shrubland	moderate (70-90%)	moderate (70-90%)	unfavourable

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