Data Zone
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'):| Species | Current IUCN Red List Category | Season | Year(s) | Population estimate at site | IBA criteria met |
|---|---|---|---|---|---|
| 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 | VU | resident | 1990-1999 | common | A1, A2 |
The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2001).
