The site was identified as important in 2001 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:

Species	Red List1	Season	Year(s)	Size	IBA criteria
Philippine Duck Anas luzonica	VU	resident	1990-1999	present	A1
Mindoro Bleeding-heart Gallicolumba platenae	CR	resident	1990-1999	present	A1, A2
Spotted Imperial-pigeon Ducula carola	VU	resident	1950-1959	present	A1
Black-hooded Coucal Centropus steerii	CR	resident	1990-1999	present	A1, A2
Mindoro Hornbill Penelopides mindorensis	EN	resident	1990-1999	20 individuals	A1, A2
Scarlet-collared Flowerpecker Dicaeum retrocinctum	NT	resident	1990-1999	common	A1, A2

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2001) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2018) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	-	moderate (70-90%)	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happening now	majority/most of area/population (50-90%)	very rapid to severe deterioration	very high
Biological resource use	happening now	majority/most of area/population (50-90%)	very rapid to severe deterioration	very high
Agricultural expansion and intensification	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Other	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

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Some of site covered (10-49%)	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	low

Year	Protected Area	Designation	% overlap with IBA
