The site was identified as important in 2008 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2008) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2008. The most recent assessment (2022) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	poor (40-69%)	very poor (< 40%)	very 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%)	very rapid to severe deterioration	high
Climate change and severe weather	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Biological resource use	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Residential and commercial development	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Natural system modifications	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Transportation and service corridors	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Pollution	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Geological events	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
Little/none of site covered (<10%)	No management planning has taken place	Very little or no conservation action taking place	negligible
