The site was identified as important in 2010 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 (2010) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2010) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Residential and commercial development	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Human intrusions and disturbance	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Pollution	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Climate change and severe weather	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Agricultural expansion and intensification	likely in short term (within 4 years)	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Transportation and service corridors	likely in short term (within 4 years)	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
No known threats	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
Some of site covered (10-49%)	No management planning has taken place	Very little or no conservation action taking place	negligible
