The site was identified as important in 1998 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (1998) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1998. The most recent assessment (2013) 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
Forest	moderate (70-90%)	moderate (70-90%)	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	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

Climate change and severe weather	likely in long term (beyond 4 years)	majority/most of area/population (50-90%)	moderate to rapid deterioration	medium
Energy production and mining	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Transportation and service corridors	happening now	some of area/population (10-49%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Most of site (50-90%) covered (including the most critical parts for important bird species)	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
