1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2004) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2016) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Cerulean Flycatcher Eutrichomyias rowleyi	23	34	individuals	100	favourable
Sangihe White-eye Zosterops nehrkorni	1	0	individuals	0	very unfavourable

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Artificial/Terrestrial	poor (40-69%)	moderate (70-90%)	very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Geological events	happening now	majority/most of area/population (50-90%)	very rapid to severe deterioration	very high
Biological resource use	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
Agricultural expansion and intensification	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Human intrusions and disturbance	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Natural system modifications	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
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
Little/none of site covered (<10%)	No management plan exists but the management planning process has begun	Some limited conservation initiatives are in place	low
