The site was identified as important in 2008 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 (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 (2018) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	-	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Residential and commercial development	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
Biological resource use	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Natural system modifications	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Invasive and other problematic species and genes	happening now	whole area/population (>90%)	slow but significant deterioration	high
Agricultural expansion and intensification	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

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 plan exists but the management planning process has begun	Very little or no conservation action taking place	negligible

Habitat1	Habitat detail	% of IBA
Forest	Lowland forest - mixed swamp, Mangrove forest (tropical)	major (>10)
Marine Intertidal		major (>10)
Marine Coastal/Supratidal		minor (<10)

1. IUCN Habitat classification.

Land use	% of IBA
agriculture	minor (<10)
fisheries/aquaculture	minor (<10)
other	minor (<10)
